This is my first quad core build(specs below). I was having issues with vista installed very very slowly. I installed prime95(32-bit) and after 15 minutes or so i get hardware errors and random cores stop testing, the last time i tested i had speedfan running, and it reports that my cpu is getting up to 89Celsius. (nothing is overclocked). Is this too hot, and why does the test keep failing?

Intel i7 920 2.66
intel ssd drive 80gb
ASUS P6T Deluxe V2
6gb of ram 1600 (3x channel)
1 (XFX ati 4890)

1st thing when i saw the temp "O_O YEAH THATS TOO HOT. O_O" It should be below 70 for the safe zone. my processor (AMD 5600+) runs at about 28-34C all the time and gaming 38-49C depending.

couple questions, are you using an aftermarket cooler? whatever cooler you are using my guess is that the heat sink isn't mounted right or you've got too much thermal paste.

You need to buy some thermal paste and reinstall your heatsink. i7 runs hot and the stock heatsink wont keep it under 75c, but anything over 80c is ridiculous.

Somehow in the bios the smart fan technology got turned off so when the temp would rise the fan would not spin any faster, after i turned that on the temp dropped. I also cleaned all the factory thermal paste off the processor and heatsink and now its been running a prime 95 torture test for almost 12 hours with no problems (all cores running at 100%) 72Celsius.

Also does quality/brand of thermal paste really make that much difference? Im thinking about buying the coolermaster v8, any comments?

You need quality thermal paste for many reasons, just get Arctic Cooling MX-2/3, OCZ Freeze, or Tuniq TX-2.

Also get the Xigmatek Dark Knight, it will perform better than the V8 for less money.

My Dark Knight lets it get up to 82c in Prime95. Then again I am clocked to 3.5GHz with 1.325V.
