Nowadays CPU’s are running faster and faster. Nevertheless which most people don’t realise, they are also running hotter and hotter. Introducing the Zalman CNPS7000A-ACu CPU Cooler, designed to fit Socket 478, Socket 462 and Socket 754.

Most people, who own a Pre-Packaged standard machine (bought from Dell or others) may think that it’s absurd to replace a “certified” Intel or AMD Heat Sink Fan. The truth is that most CPU’s run rather hot and thus causing irreversible damage. Zalman is a company who’s had plenty of experience in making CPU coolers, and is regarded highly in the Computer Market today. Its past history stems back to Socket 370 CPU coolers (Pentium 3) and definitely knows its stuff. For its recent products it’s changed the installation method, so it is now easier to attach this beast to your beloved electronic investment.

The Zalman CNPS7000A-ACu Includes:

Common Parts
1) FHS Assembly (CNPS7000A-Cu)
2) Four (4) Bolts – For fastening the clip
3) Thermal Grease
4) Adjustable Fan Speed Controller (FAN MATE 1)
5) Installation Manual – in English and Korean

Parts for Intel Pentium 4 (Socket 478)
6) Two (2) Clip Supports for Socket 478

Parts for AMD Athlon/Duron/Athlon XP (Socket 462)
7) Clip Support for Socket 462 – Type A (Blue)
Clip Support for Socket 462 – Type B (White)
9) Four (4) Bolts – For fastening the clip support
10) One (1) Sheet of Washers

Parts for AMD Athlon 64 (Socket 754)
11) Two (2) Nipples
12) One (1) Back plate
13) Use the larger washers from part #10

We installed it on a Pentium 4 system which is a breeze, when compared to the other socket installations. Utilizing the existing attachment mechanism, aluminium bars are inserted into, followed by the cooler which simply with screws, screws on. Make sure you apply the thermal grease beforehand on the CPU, included in the packet. The total weight of this beast is a respectable 445grams, which is just under the Intel specified max weight of 500grams.

One installation problem we encounted (which wasn’t on Zalman’s end) was that the standard Intel Heat Sink when used for a while actually sticks to your CPU. Once you pull the CPU fan off, it pulls out the CPU attached with it, off its seat! By fluke, it wasn’t damaged, and it easily came off by twisting it. Intel should really consider replacing that black thermal stuff! More information on this horror is here: http://forums.devhardware.com/showthread.php?threadid=11520&s=

The CPU Cooler consists basically of a slab of metal (which is numerous bolted fins together) and a Huge Fan. The heat sink metal is an alloy of copper and aluminium which aids cooling significantly. The heat sink is rounded, due to its unusual shape and structure. The massive fan (or some may call propeller!) sits in grooved into the Heat Sink and thrashers around air to cool down your CPU. The dimensions of the CNPS7000A-ACu CPU are 109mm (L) x 109mm (W) x 62(H), with a total dissipation area of 3170cm squared.

Temperature during Normal Operation:
Intel HSF: 45 Degrees Celsius
Zalman CNPS7000A-ACu: 39 Degrees Celsius

Temperature during Max Payne 2 (a CPU intensive application):
Intel HSF: 55 Degrees Celsius
Zalman CNPS7000A-ACu: 48 Degrees Celsius

The performance of the cooler is significantly better than the stock standard Intel HSF and keeps the temperature down while your computer is on, and keeps it sane through the most CPU intensive applications you can think of.

Overall the Zalman CNPS7000A-ACu is an essential purchase for anybody who respects their CPU and wants to keep their most critical component cool. The quality of the cooler is superb, and it looks cool too! The only problem with the product is that the thermal grease is a little small, but even though we tested it with the included thermal grease the results were still respectable. The only downside to the product is that they don’t specify that if you are replacing your HSF, your going to be in for a wild ride. Mind you, its Intel’s fault they use that metal carbon substance.

This product retails around $90 AU

Zalman CNPS7000A-ACu

Remember that old GeForce 3 Graphics Card laying around with the buzzing heat sink fan? Or perhaps you decided to extend the life of and want to protect you’re newly purchased Graphic Card Investment? Introducing the Zalman ZM80C-HP + OP1 (Option Pack 1), is the latest and greatest cooler from Zalman, and is designed to cool your graphics card without excessive noise. This product alone is literally silent, but with the optional pack (which is a fan and mounting kit) just raises the bar from whisper quiet.

The Zalman ZM80C-HP is packaged in a moulded, hard plastic pack. It includes:

• The Two Heat Sink Plates with Patented Design.


• One pair Aluminium blocks which attach to the top and underside of the Graphic-card Chipset. There is also included a larger pair of blocks, for chipsets with a larger GPU.


• A bag with all the necessary screws, support braces, grommets, a thermal grease tube and gold coloured end caps.


• In addition another bag, containing all bits you may loose from the first pack, as well as another thermal grease tube.


• The unique but critical Zalman Gold-Plated Copper Heat-Pipe.


• A screwdriver.


• And a case sticker or appliqué.

Once all the components are laid out on a solid, static-free area, you soon realise that it is one big cooler! Not only does it look impressive, but it serves a beneficial role in cooling Graphics Cards which nowadays, heat is the biggest hardware killer.

Basically the Aluminium heat blocks transfer the heat off the Graphics Processing Unit (GPU) and lead them to the Cooling Plates. The special, gold plated copper pipe contains gas which effectively allows the radiating heat to distribute between the front and back cooling plates allowing even heat dispersion. It seems that the cooling plates are a little too far to cool the RAM, but a further investment may leap you into getting individual RAM Heat Sinks, although this seems unnecessary. The total heat dispersion area for this cooler is a stunning 1200cm2. In total the heat sink weighs 325 grams.

For our test, I fitted an old GeForce 3 card with the product. It seems overkill but the fan was a weird shape and couldn’t be replaced by conventional methods. The assembly of the Zalman ZM80C-HP onto the card is a little tricky, as it requires holding certain parts of the Heat Sink whilst screwing in the Aluminium heat transfer blocks. Installation is not difficult per se, but if followed correctly, and accompanied by a helping hand, it’s defiantly worth the effort. I was surprised to see that they didn’t include a small spatular, but a simple overhead sheet can be turned into a professional Thermal Grease applicator. It also seems the Thermal Grease tube says to “Avoid contact with skin and eyes” but if you’re like me, make sure you regularly clean your hands to avoid coating your entire Graphic Card with the stuff.

OP1 or the Option Pack (purchased separately), basically is a thin 80mm fan with accessories that attaches to the upper outer edge of the Cooling Plate. This enables greater cooling (namely active cooling), at the expense of some noise. The Molex splitter included lets you choose between Silent Mode – 1400 RPM (5V) and Standard Mode – 2800RPM (12V). Either one you choose, the standard mode is still a little louder than whisper quiet. The fan overhangs the cooler but doesn’t oscillate, and aids in the cooling of your PCI Cards positioned below. Installation takes approximately 15mins max.

Temperature was recorded after running Age of Mythology, with all settings turned on high. AOM was used to be a median between hard core graphics, and not so intensive graphics.

The temperature after 5 minutes @ ambient temperature of 30 Degrees Celsius:

Original Heat Sink Fan: 43 Degrees Celsius

ZM80C-HP = 35 Degrees Celsius
ZM80C-HP + OP1 Silent Mode = 29 Degrees Celsius
ZM80C-HP + OP1 Standard Mode = 23 Degrees Celsius

(Note: these temperatures were acquired on a GeForce 3 chipset; a faster chipset generates more heat and so forth so newer cards will have a higher temperature.

Overclocking wasn’t tested, due to the fine variables and the fact that Zalman doesn’t condone Overclocking. (Which in turn D-GAME doesn’t recommend it either). Generally speaking, the Cooler would defiantly be able to take, and allow greater core clock speeds to be pushed and achieved due to its fantastic head dispersion method.

Overall, I must say that when the product arrived, I was surprised to see the quality and practicality offered from the ZM80C-HP + OP1. Zalman really thought about what was required and was very clever to include optional bits and pieces, as well as plenty of Thermal Grease. On the other hand the ZM80C-HP + OP1 weighs a considerable amount, which makes carrying the computer if unsecured properly, a little hazardous. Also the removal of the standard Graphic Card’s Heat Sink fan invalidates the warranty, which for a new card, is a huge risk to take.

So finally I conclude that the ZM80C-HP + OP1 is value for money and if installed correctly, will enhance and improve your day to day computing experience.

This product retails around $60 AU without OP1.

The AeroMaxx with TMD fan is not just another cooler, it’s like a gadget off McGuyver. There is no center hub mounted motor. The motor has been designed and placed “around” the fan, pretty cool huh? What this does is allow for more airflow through the fan, directly onto your cpu (cooling area). Looking at the fan, the overall general appearance is not much different that other cpu coolers, but take a closer look.

Underneath the center of the fan, you will see the copper insert of the actual cooler, no fan hub or motor to block air flow. Installation is straightforward, and simple. Just like other coolers, be careful to take your time and be gentle. And use some heatsink compound, but not too much.

Performance

To get the performance data, I ran my pc at idle, and under full load for a specified amount of time. Using both stock cooler and the AeroMaxx.

Test machine:

• 
  
  P-4 2.53


• 512 Mushkin ddr pc-2700


• Asus P4PE


• 100 gig WD HD


• 120 gig WD HD


• 16x Sony DVD


• 12x Plextor CDR-RW

Testing results

• Running my cpu with stock cooler at idle for an hour, room temp@74f, my cpu temp stays stable at 107f. After an hour of constant online gaming, (Medal of Honor), cpu temps would peak and stay @ 119f.


• With the AeroMaxx cooler, idle cpu temps were 105f. After an hour of online gameplay, cpu temps would peak and stay @115f. Give or take a degree or two for motherboard monitor accuracy.

All temps were taken using Motherboard Monitor 5.2.1 (I know I need to update mine).

Conclusions

• Beautifully designed/looking cooler with a great new fan design, to improve airflow and cooling performance.


• Copper insert.


• Quiet.

This cooler is one to remember. The fan design is something other cooler makers need to take note of. The efficiency and low noise level makes this a true winner. Easy to install, comes with small syringe of thermal grease. Heatsink edges are VERY sharp, be careful. I would recommend this cooler to anyone looking for a mid priced high performance cooler.

Thanks to Coolerguys.com for the test unit.

AeroMaxx CPU Cooler

A big thanks goes out to Scott of HighSpeedPC for not only supplying this kit, but giving me the extra equipment needed to test it to the best of my ability.  It an honor to work with such a courteous man.  Here’s to you.       

Watercooling despite the anxiety and fear of mixing water and electronics has become more and more mainstream. What started with homebuilt systems consisting of an eclectic collection of odds and ends have been transformed to an industry where the products are professionally manufactured. Companies have started pushing out kits that not only provide all the necessary pieces to assemble a quality watercooled setup but have made it easy to implement, allowing even the inexperienced to tackle what has once been the realm of the experienced. Innovatek, although quite new to the field, has made an exceptionally crafted kit that is not only easy to assemble, but performs well to boot.

An Introduction to Watercooling
When compared to regular air cooling, watercooling seems downright dangerous mainly because of the water and the numerous parts that are needed in a proper setup. In a typical air cooling setup there are two main variables: fan operation and heatsink mounting. A typical watercooling setup has many more variables ranging from fittings to the pump. The more complicated something is, the greater chance that something is likely to go wrong. That said an improperly installed watercooling setup can destroy your computer. Knowing the risks beforehand can help lower the probability of catastrophic disasters from occurring, but will not prevent them.

Knowing that watercooling is more of a risk, why? There are two main reasons: cooling capacity and noise. Water has a much higher thermal capacity then air and can more efficiently remove heat, meaning that your processor and any other chip in the cooling loop will run cooler. Whether this leads to a higher overclock, or just greater stability, it is just the luck of the draw. Watercooling promises nothing but lower temperatures in a well designed setup. An air cooled setup depends on a fan to help force air to pickup heat, the greater the flow, the greater then performance; unfortunately comes a greater noise level. Because of this higher thermal capacity, coupled with the use of larger fans, watercooling is characteristically quieter as well while offering lower temperatures.

There are three main parts that makeup a typical setup: the waterblock, pump and radiator. The waterblock is the heart of the system; it is the piece that attaches to the processor. There are many variations that try to increase turbulent flow and surface area to better cool the processor. Water flows into the block via one or more inlets and out one or more outlets picking up heat as the water rushes by. This water is than directed into a radiator or heatercore to be cooled, a coil of tubes with fins bonded together to maximize surface area, which is often assisted by a fan analogous to the fins in a heatsink. The pump is rather self explanatory, keeping the circulation of water going through the system. Of course, there are more elements, but these are just the basics.

What You Get
The entire kit arrives in a stylish box adorned with the Innovatek logo on all sides. Inside, all the pieces were well packed into molded foam, ensuring everything will arrive in perfect condition to your door step. My Innovatek kit includes:

1 x InnovaCool Rev 3 Waterblock
1 x Ehiem 1048 Pump (including 2 x ½ Fittings, 1 x Thread Adapter)
1 x Maxxxpert Mono Radiator
1 x Innovatek Inline Reservoir
1 x YSTech 120mm Fan
1 x 120mm Fan Guard
1 x 3 Pin to Molex Fan Adapter (7V)
1 x Artic Silver III Syringe
1 x Spare 8mm Compression Fitting
4 x 8mm Elbows
8 x Zip Ties
8 x Black Fan Screws
6 Feet Stock Vinyl Tubing + 6 Feet 5/16 Tygon

Although there are no instructions included with the kit, there is an excellent one at HighSpeedPC’s website that details installation step by step.

Innovatek P4 Kit

A big thanks goes out to ThermalRight and Zalman for providing samples.

With Intel and overclockers pushing the Northwood core to speeds in excess of three gigahertz and beyond, cooling solutions have never been so prevalent. The Intel stock heatsink is a great performer in its own right, but better heatsinks are needed by overclockers to push the limits of their processors. Here we have three high end Pentium 4 coolers ranging Alpha using their traditional forged pin design, ThermalRight with an offshoot of the popular Athlon-based AX7, and Zalman with a revision to their paradigm bending flower design.

Alpha PAL8942T

Material: Copper/Aluminum Hybrid
Size: 78.5mmx90×42 (LxWxH)
Weight: 534g
Bundle: Heatsink, fan shroud, mounting hardware

Alpha has always been associated with high performance coolers. This heatsink is a hybrid, like many others on the market today. The common misconception used to rationalize these designs is aluminum dissipates heat more quickly while copper can absorb it more quickly. The real reason behind this design is to maximize the efficiency of the heatsink based on weight. Copper does have a higher conductivity than aluminum by volume, but aluminum has a higher conductivity by mass. Using a hybrid of these metals gives the best trade off between conductivity and weight. The base is made from a solid piece of copper which has been machined to be quite smooth and flat, despite the presence of machining swirls. Using their forging technique the aluminum pins are, for all intents and purposes, a part of the copper base allowing for the best heat transfer possible. These hexagonal pins are anodized black, meaning that aluminum oxide has been “grown” on the surface of the aluminum creating a very hard coating. Anodizing does not hurt performance except when used on the mating surface with the processor because of its extremely porous and crystalline structure; that’s why it can accept dies readily. The Alpha comes with an aluminum shroud to direct air flow as well as raise the fan above the heatsink about five millimeters to reduce the dead-spot underneath the fan rotor. 

The worst aspect of the Alpha is the mounting system. Instead of using the standard retention mechanism, the heatsink must be installed via the four mounting holes around the socket, necessitating the removal of the retention mechanism and motherboard. Each of the four holes requires one standoff, two washers and one nut. Once they are installed, the heatsink needs to be screwed into the standoffs. To maintain even pressure on the processor, the screws have to be tightened little by little (in the same fashion as installing a tire) until the screws have bottomed out. The shroud simply drops onto the heatsink and the fan is screwed into the heatsink base. Alpha does not bundle a fan, thus allowing end users to customize the heatsink to their needs. Installation really is not a hassle if only done once, but is quite a pain of done many times. Often times the standoffs will release from the motherboard when removing the heatsink causing me to go on an hour hunt for tiny, clear washers; for a semipermanant solution, a drop of superglue would do the trick.

Pentium 4 Cooler Roundup

Thanks out to PCMods for providing this sample.

Lighted fans seem to be the current craze with the slew of reviews coming out. A complaint of my and others have been that many are not of the highest quality and available in sizes other than the standard 80mm. Typically, these fans are made of clear plastic with LEDs embedded in the rotor or along with casing. The PCMods light fan diverges from the status quo by modifying a top quality fan addressing many of the qualms I have, but also introducing some others.

The PCMods lighted fan is built around the exceptional Panaflo 120mm H1A made by Panasonic. Like all fans made by Panasonic (except for 40mm models), this fan features their Hydro-Wave Bearing, basically a sleeve bearing that uses a film of oil to reduce friction, thus allowing the fan to have a high cubic feet per minute (CFM) to decibel rating. This fan moves a healthy 103.8 CFM at 41.5 decibels, which could seem quite loud. But, the larger size of the fan produces a lower pitched sound, making it seem quieter than the whine of a smaller fan rated at the same sound levels.

Because the Panaflo is not made from a clear plastic, PCMods had to modify the fan to accept the LEDs. Fortunately or unfortunately, this review lends itself to more pictures than words, so this review will follow accordingly. To do this, they permanently bonded a plastic disk to the back of the fan rotor with three fiber optic like strands radiating from it. These strands then are inserted into holes that have been drilled into the fan blades at three different positions to create three rings of light when the fan is powered on. Looking at the front of the fan, one can clearly see the strands poking through the blades. Clearly, any modification of the fan blades or rotors disturbs the balance of the fan and will cause it to shake. Time can only tell what effects this modification has on the life of the fan. The effects of this modification will be discussed later.

The heart of this fan is the PCB mounted diagonally across the backside on two large spacers. Not only do the spacers add about 40mm to the depth of the fan, making it 78mm thick overall, the placement of the PCB limits the fan usefulness to just being an exhaust fan. But nevertheless, the PCB is well made with an actual power plug rather than soldering the wires directly on. The LEDs are also socketed, meaning that they can be easily replaced with different colors to create color swirls and other patterns. Both the fan and the PCB have their own male Molex connectors connected to the provided “Y” adaptor.

With the fan powered on, the LEDs do put on quite a show. Here the effects of the fiber optic placement come into play, creating three rings of distinct color. Because of the socketed LEDs, I was able to swap place two green LEDs along with the red LEDs PCMods provided. But, the provided LEDs where so strong that they completely drowned out the green. Because of the way the fan is made, it is not possible to make the three rings different colors.

Now, we already touched upon what modifying the fan would potentially do. First of all, throwing off the balance causes a decreased life span because of increased friction. Second, it causes the fan to shake and vibrate. This it does do, but not to the extent I though it would. However, if you place the fan on a hard surface, expect it to move. Be sure to purchase some rubber washers too. Third, the PCB might create more noise because it in the flow path of the fan. Fortunately, this was non existent.

Final Score and Last Comments

Like many products, this fan falls into a market niche. If you are into lighted fans and want the larger fans sizes, PCMods offers lighted fans of all sizes as well as a kit to do the modification yourself, this product would fit the bill quite nicely. Although the implementation introduces some problems of its own (vibration and mounting) the good qualities negate them. Not does the lighted fan use a top quality Panaflo fan, the workmanship is top notch, and the inclusion of socketed LEDs makes this product much more versatile.

PCMods Lighted Fan Review

Just a Fan…or not.

When is a fan not just a fan?  This is a question for the case mod junkies out there, who are constantly looking for new and exciting ways to dress up an otherwise drab computer case.  With the internal temperatures of a computer case being such a concern, adding additional cooling fans is not only a trick mod, but a necessity.  For the average user, a simple black 80mm case fan would do the trick, but for the guy with a Plexiglas side panel and multiple exhaust fans, simple is not an option.  The OC Systems 80mm Clear Case Fan with Blue LEDs is an inexpensive way to add some instant coolness-factor to your case, with very little effort or risk.  Remove the existing case fan, drop in this 80mm replacement, plug in the power leads, then sit back and revel in the glowing blue lights.  And we all know how cool blue lights are, as opposed to the other colored lights out there.  Something about blue LEDs just makes them cool.

So how exactly do you review a fan?  Honestly, there is not a lot to say other than covering the specs, and giving you an idea of what this fan has to offer over a standard 80mm fan.  The specs of the fan are fairly standard: 80mm, 2500 RPM, pushing 32.5 CFM.  The fan features a 3-wire cable for monitoring fan rotation if desired.  As indicated in the name of the fan, the construction is of a clear plastic, with two blue LEDs mounted in the center hub.  Under low light conditions, the fan blades glow a cool blue when the fan is in operation.

We installed the fan in two different cases, testing out various mounting options and lighting effects for the LEDs.  Our first test placement was the Antec 1080 Plus, with the fan installed in the front intake position.    The LEDs lit up the front grill of the case well under lowlight conditions, and with the tool-free design of the 1080 Plus, this was a 10-second case mod.  Perfect for a guy like me who is short on time, but still likes cool toys.  Our second, and overall better placement, was in the new Color Cases Stealth X.  This case features a Plexi side window, with a central 80mm fan location in the window.  With a window mod, the inside of the case gets a nice blue glow in lowlight conditions, while the clear construction of the fan complements the window in bright lighting.

I’m going to dispense with the standard ratings on this review, since there is not a huge amount of data to compare.  It is a fan, and it blows a fair amount of air.  The fan is also very quiet, which is a good thing.  The clear construction is slick, and the blue LEDs are a very nice addition to any case out there.  Even if you don’t have a window kit installed, the fan can still add a little coolness to your case, as illustrated by our Antec 1080’s front grill.  These things are selling for as low as $5 each, which is not that much more than a standard 80mm case fan, so they pretty much a bargain, too.  Just be sure to factor in shipping and handling costs when ordering online, since it adds to the final cost of an item.  Overall, this is a quick, painless case mod I would even recommend for my grandma.

OC Systems Clear 80mm Blue LED Fan

In the world of computers, this statement holds true for all of us. So what can be done about it? Well, first of all, you can research different methods of cooling your pc. Whether it be a cpu cooler, hard drive cooler, or add an extra case fan.
In this article, I am reviewing a couple of case fans, not your ordinary fans at all.
The units I will review are the “Plus” and “Turbo” models they offer.
The idea and units themselves are rather simple, blowing cool air where it is most needed, at the hotspots of the inside of your pc, the video card and he processor.
The models of these units vary according to the fan…

• “The 2COOLPC-PLUS has a server quality, double ball bearing fan that pushes about 50 CFM with a .3 amp power draw and a life expectancy of 64,000 hours MTBF (About 7 Years). “
• “2COOLPC-TURBO 60 CFM POWER!Made with a 60 CFM 92×92x25 mm Double ball bearing fan.
  2900 RPM.39 Amp Power Draw. 55,000 Hour life expectancy
  (Has Y Style Molex Power Connection)”
