New rig overheats
Howdy all,
As the title sugests, my new rig overheats. It's a complete custom build, all parts are new. I checked for component compatibility and everything is groovy. The temps I reach at Idle are: CPU 50 C MoBo 40 C RAM 50 C (give or take) A little history: The problem manifests as an overall system instability (lock-ups, a few rare blue screens). As I didn't suspect it was a heating issue, I changed the power supply (thought I might be short a few Watts considering my first PS was an ULTRA 550W modular). That wasn't it. Then I thought It was the MoBo so I traded in my old EVGA 680i SLI MoBo for the ASUS Stryker Extreme. That wasn't it. Of course by that time I ran several memory tests, switched up my RAM in every x4 or x2 configuration possible. That wasn't it. I also checked my H.D.D., formated, tried without a RAID 0, tried reseting my RAID config. That wasn't it. Then I figured... Processor? RMA the processor for a new one. That wasn't it. I'm pretty shure my cooling is ok. Zalman 9500 CPU fan is well rated and liked by the community. I have 1 120mm case fan pushing air in at the front of my case and one at the back pushing air out. The ULTRA aluminus is very spacious and I uncluthered the wires as to facilitate airflow Fellas, I am desperate, help me please, I am all out of Ideas |

What CPU are you using? And what powersupply did you put in as a replacement?

how well is the cpu cooler seated on the processor is there an excess of cooling paste? A very thin layer is all that you need

Power supply: PC POWER AND COOLING silencer 750 Quad
Processor: Intel Core 2 Duo E6700 Oh and just to rule out the basics, yes I did apply a sufficient amount of heatsink compound. I also thought my fan Zalman might be defective so I ran some tests with the Intel Fan that came with the processor and I had the same problem. As for cooling, I know the Vantec stealths aren't the most powerfull fans on the market but it still shouldn't explain these temperatures... Here are the fan's tech specs anyways: Model: SF12025L Fan Size: 120x120x25mm 4.72x4.72x0.98" Voltage: 12 V Current: 0.08 Amp Airflow: 53 CFM Power: 0.96 W Noise: 28 dBA Speed: 1500 RPM Bearing: 2 Ball Bearings |

The socket 775 heatsinks are really hard to install correctly. Take the motherboard out of the case and follow these instructions: Intel 775 Stock HSF Install Guide
Don't be afraid to bend the board. Make sure you're using a bb sized amount of arctic silver. Depending on the temperature in the room and the cooling fans on your case, that processor should idle in the 30s. |

I spread a thin layer on both my heatsink and processor. I was out of the original paste that came with the fan so I ordered up the "super special" heatsink paste from Zalman (supposed to be 50 times better than regular paste... it might also cure cancer). Anyways, the bottle cap has a brush so applying in a thin layer was easy.
As for the seating arrangements, it's all snug. Screws are in tight. I did a jiggle test and it passed with flying colors. Oh and yes I upgraded my MoBo BIOS so that's also groovy. Honestly, I think I might be cursed. |

Download CoreTemp to double check the cpu temperature. My experience is that ASUS mis-reads the C2D temperatures by quite a bit. Sorry I forgot about that earlier :-)

Just how much thermal compound did you put on the CPU and heatsink? You only need a very thin layer...it's purpose is to fill in the microscopic gaps in both surfaces. You still need metal-to-metal contact between the CPU and the heatsink so that thermal transfer can occur. If you put too much thermal compound it acts like an insulator and your get higher temps.

Zalman 9500 doesn't have prongs. It's all screws. You screw a base in and then screw the fan on top. MoBo was out of the case as I installed. And i'm certain it's mounted properly.

How big an issue is a scratch on the heatsink? I noticed a tiny one... And when I say scratch, it's tiny and barely noticable...

it depends. Usually not too big. What temp reading does coreTemp give you? And, out of curiosity, what program are you using to get temperature readings right now?
