Case Fans and CPU Fan/Heatsink
Hi, I'm building a new computer and I need a little help choosing case fans and CPU fan/heatsink. The case fans are 80x80x25. I will be running an AMD Athlon XP 2800+. Quiet is a major priority. Thanks in advance for the help.

From what i have read on these forums you just dont get quiet AMD computers. If quiet is that important you may need to go with Intel.

For case fans I suggest Sunon 80mm ball-bearing, they are relatively quite and move a lot of air. Plus, they're $5 apiece. I don't know about a HSF, what's out there now that can handle a 2800+?

The Sunon's that AWD suggested are good, plus you might check out the Vantec Stealth fans and fans by Panaflo. All are good and about as quiet as you can get while still moving enough air. I don't know about the HS fan though either.

Hi ,
Currently, there is nothing listed on AMDs Thermal Solutions Page for a 2800+. Follow the links to sites for the 2700+ and you'll probably find one. TwoRails |

I don't really understand how such falsehoods get spread like this... It is one of those things that is simply not true. Every box I've built for myself or for others have been virtually whisper quite. Plain and simple. Any box, AMD or Intel, can be noisey if you want to stick in a 1/2 dozen 7000 RPM fans into it. And there is no need to, yet people like to do such things. TwoRails |

I have a XP 1600 that runs in the low 40'sC in a Chieftec case with a Enermax 340W power supply which has two fans. Case has 1 input and two exhaust 80mm ball bearing fans and CPU has a Alpha Pal 8045 with 80mm whisper fan. It's setting under desk (not enclosed) and I can barely hear it. Loudest fan it it is the chipset fan on video card that is noticeable with case side off.
In short, TwoRails is correct. Get quality ball bearing fans. Go with 80mm when possible and stay away from 6000 and 7000 RPM fans. Faster equal noise. Chas

Just for the record i am not a WinTel advocate or AMD, i was only passing on the views of most of ? the posts on this site. I am in the proccess of getting all parts for my first build which will be AMD.

Thanks, Cricket, for the scolding -- It's what I deserve for trying to knock out a few posts before going to bed after having a few too many cold one!!   (Hope you didn't overlook my prior post with a link to AMD's Thermal Solution site.)TwoRails, the Hungover

You're probably thinking of Thermal Protection differences between the two. Intel chips handle TP better than AMD, and until the XP, AMD didn't have much protection at all. Even with the XP, TP is more a function of the motherboard than the chip itself, where Intel's protection is more of a function of the chip. That is far different than the noise levels required to keep a chip (CPU) cool. A CPU that burns 70 Watts of energy will put out the roughly the same amount of heat energy, regardless whether it's Intel or AMD -- therefore, their cooling requirements will be the same, which means the noise levels will be roughly the same. I say "roughly" because of minor differences, like the size of the chip's heat spreader and the like. If things like the heat spreader were identical, then the heat given off at 70W would also be identical. And good luck with your new build, Dangermouse1 !! TwoRails |

juppy already mentioned Vantec Stealth and Panaflo fans (which is what I would have suggested). The last two AMD systems I put together used all copper heatsinks with high RPM fans and they're pretty noisy. The two AMD system's before that I used aluminum Cooler Master heatsinks that weren't too noisy, but I forget which models I used. I've been building mostly INTEL PC's lately and haven't been keeping up with the heatsinks available for AMD CPU's so I don't know which ones are good if you want a quiet PC. Thought you could suggest some good ones. Cricket

Hi Kurt871,
The above mentioned case fans are all good units, as well as other brands, like Antec. The key to quite is basically CFM (Cubic Feet per Minuted of air flow) versus RPM. This is to say that a 80mm fan pulling 38 CFM at 3000 RPM will be much quiter than a 60mm fan pulling the same 38 CFM at 7000 RPM. Manufacturers will give the noise level (db) of their fans. So, a higly effiecent, well designed fan will also be much quiter than a poorly designed unit with the same CFM and RPM specs. You may not even need to buy additional case fans because many case already ship with one or two fans, like Antec cases (my personal favorite). I've had my 1800+ running in three different Antec cases and it runs very consistent at 40°C. The fan arrangement that came with the cases are: 1) one front fan, 2) one rear fan, and 3) currently two rear fans in my "Performance Series" case -- yet they all cool the same. I haven't run the 2800+ Yet, but I'd have to say / guess that it's no different than prior AMD chips in that the "stock" or "factory" HS/Fan combo will not only do a good job of cooling, but do it quitely as well. This is to say that virtually all my builds have been with the stock fan and have been very quite. Yes, I've experimented with what I call "fancy" and expensive fans, but the 1 or 2° of extra cooling have Not been worth the extra money or extra noise. I returned them all and put the stock unit back on. I typically pick a CoolerMaster HS/Fan unit when buying the chip as an OEM unit, or use whatever is shipped with the Retail unit. HTH TwoRails Edit: PS: one thing I usually do if buying OEM is to buy a HS/Fan combo for the next size or two up of the CPU. While this won't help with a 2800+, it sure works for prior CPUs. For example, the combo on my 1800+ right now is actually rated for a 1.4 T-Bird which is also good for about at 2100+ or 2200+. Last edited by TwoRails; 12-07-2002 at 12:49 PM. |

Hi Cricket
It was meant in a good way And I certainly didn't mind.TwoRails PS: Gee..... I guess I still didn't mention any distince model number.... My stock is out in the work shed to get numbers off of, and I'm still sitting 'round in my shorts trying to wake up from last night

wow, i didnt mean to start an AMD/Intel war here
BTW, thanks for all the help, guys. Ive decided to downgrade to a 2600+, and go with 1 Panaflo 80mm intake in the front, 2 Panaflo 80mm exhale vents in the back, a Thermalright SLK-800 paired with another Panaflo. Hows that sound? thanks again.Kurt |

"Hows that sound?"
LOL !! Nice pun The case cooling should be more than good. I tried finding details on that HS (I know it's a good one, but I wanted details), but it's hard to do. It's not on AMD recommended list, and each review I read (only a handfull), it was tested on only a 1800+. I found one site that said it was rated for a 2100+. I could not find anything that sez that HS will run on a 2600+ or higher.... Anybody got anything on this?? TwoRails |

haha, lol. didnt even realize that. ill look into the heatsink thing. my other consideration was a Thermaltake Volcano 9. Ive heard it cools well, too.

I'm still looking for a HS/fan combo that specifically states it's for the 2600+ or higher, but no luck yet....
I did discover that at www.newegg.com, they now have a "PIB" version of the 2600+: IE it's the Retail version with an approved HS/fan combo, but there's no mention of make or model... TwoRails |

A ' roar ' is the only description for my recent ASUS/Athlon build.
Foam insulation has helped. You can get self adhesive 2mm foam at WallMart craft Dept, Michaels and other craft shops. Both sticky back and none sticky back are in the same pile so be aware. Weird colors, the black always seems to be sold out, but who's looking inside. Its called Darice Foamies. 33 cents for a 9x12" sheet. You'll need about 8 for a large case. I'm also going to investigate some lower revving fans when I get a chance. Chris. |

HI Parangles,
What kind of cooling setup did you use? TwoRails |

Two Rails I would have sworn I replied to this, but I don't see it .
Definately having a very bad day today. Anyway ...... I bought the board and the Chip online and then went into a local shop and asked for a case fan and chip fan . From reading this thread it seems there are quieter, slower running fans. My setup is standard I guess- case fan at the bottom pulling in, fan on CPUs heat sink, and power supply blowing out the back. You'd think the mobo manufacturers could set it up to have the board monitor and control the fans speeds based on the usage and how hot it was at any moment. Cheers, Chris. |

Hi Parangles,
I hear ya about missing posts. I've had many posts that, well, weren't !?!? That cooling setup you have should work just fine, and quietly. Sounds like they gave you some high RPM jobbies. If I had some extra fans I think I'd sent 'em to ya! Actually, "they" are making good in-roads on "smart" fans and the like. Most power supplies are thermal controlled instead of just being 'on' all the time (and they are often the noisiest fan in the system). They're kinda spooky, though... I've often had to hold up a proverbial match to my PS fan just to make sure the dang thing is working - while my rear fan, right above the CPU and runnning at a constant 2960 RPM, blows very cool air. At least on hot summer days, the PS fan will kick up a few revs so I can feel it with my hand.TwoRails

Nice link, wolfie... I think.... What the heck is a .m3u file and how do you play them??? I keep geting an "out of memory" error from Windows Media Player. I even rebooted and still can't play 'em...

My suggestion, if your case only has the small holes drilled in it for the intake and exhause fans, cut it out completely and put a fan grill on it. That will reduce your noise significantly. I still need to do it, once I get my butt down to Home Depot and get me a dremel.
