"Normal" temps?

post #1 of 8
Thread Starter 
I recently built a new system:

Asus M5A99X EVO R2.0 motherboard
AMD FX-8350 CPU
32GB Corsair Vengeance DDR3-1600 RAM
EVGA GTX-550Ti GPU
Corsair H80i CPU cooler with 2 120mm fans
Corsair TX 750 PSU
NZXT Tempest 410 case with 4 120mm fans

I'm curious as to what my cpu temps SHOULD be. At idle, it hovers around 35c and running prime95 will push the temps up to 60c within a couple of minutes. Even with the H80i fans running at full speed! My old AMD Phenom II 955BE with a CoolerMaster TX3 cooler ran at nearly the same temps.

Shouldn't this H80i be better than the TX3 air cooler? I am currently running the 8350 at stock clock speeds and voltages.

Thanks for any opinions or suggestions.

60C for a cpu is just a touch high. For the 8350 that is to be expected. They run really hot. Your old processor only used 125W. The 8350 uses 220W. An increase in temperature is to be expected. There isn't anything wrong with running the processor at that temp. I ran my 8120 at 60-65 around the clock for Folding and its still running great.

Wrong. The FX-8350 is a 125W processor. Only the 9370 and 9590 processors are 220W

General concensus so far is that it will start to throttle at 70c. It IS infact a hot chip and while your temps seem to be a little on the high side, I dont think it's out of the ordinary (although I do not have much experience with this particular chip. You also have to consider ambient temperatures when using a watercooler. That makes a big difference.

Things you can do to lower temps? You can re-apply the thermal paste. Make sure you use something good like Arctic Silver 5. You can try to lower ambient temperatures in the room. Make sure you have plenty of cooling across the motherboard. Lowering overall motherboard temperatures can even help bring down processor temps. As a last resort you can try lapping the processor and cpu block of the cooler. This is a method of progressive sanding to reduce the convex/concave nature of the two surfaces to give better contact between them.

You're thinking of the 9350 at 5ghz which is pretty much a 8350 at 5ghz

My bad. Although the rest of what I said still holds true. Shouldn't have to worry about 60C

OK......I was under the impression I should have gotten lower temps using a closed-loop water cooler vs air cooling. I tend to add 5 degrees for ambient temp (a couple of days ago, with the windows open, it was like 60 outside, my PC ran a good 5c cooler). And I did do some light sanding to the heatsink, using 400 grit, before I installed it and used AS5 AND followed all of the directions I could find posted by AMD and Arctic.

I'm just trying to make sure I'm doing everything possible correctly to get the most out of this build. This is my 4th rig I've built and I learn something new every time. I have to admit, this IS the most powerful (theoretically) PC I have built yet. I know, I know......a better GPU and a SSD is in the future. Due to money restraints, THIS system HAS to last for a few years.

Thanks

400 grit? You should use higher grit sandpaper! You should be starting out at 400 grit and make your way up 600, 800, 1200, and even 2000 for the best results.

Yeah, I was just guessing there......it was a very fine grit of sandpaper. I might very well have been 800 or higher.
