AMD FX-8370 + Be Quiet! Pure Rock. Temps exceeding 60 degrees celcius in 2 minutes stress testing. Is this normal?

I am having a problem with my CPU temperatures despite installing the new Be Quiet! Pure Rock cooler to replace the Stock AMD Cooler. I have an AMD FX-8370 Processor at Stock Speed.

I installed the Be Quiet! Pure Rock Cooler but with the stock thermal paste that was already attached. I remove the old one from the cpu with the thermal removing alcohol. But my temperatures are shooting up to 64 degrees celcius in only 2 minutes of stress testing before I quickly stop the process!!! Is this normal?!

Idle temps lowest is 33 degrees celcius. But when I do a full 100% stress test in just 2-3 minutes the temps would exceed over 60 degrees. I was wondering whether this is normal.

i have installed the same cooler for my mums PC that has an AMD FX-6300 CPU but her temps are low. Highest 44 degrees even after hours of stress testing while lowest 20 degrees.

But on my dads FX-8370 CPU highest so far is 64 degrees celcius before I quickly stop the process. While lowest is 33 degrees celcius. I am wondering whether these are normal results?

Or do I need an even more powerful cooler than that? My motherboard is ASROCK 970M Pro3. And my case is Aerocool X-Strike GT! Many thanks...

If the cooler is anything like the Hyper 212+ I had, mounting a second fan on the other side of the cooler should greatly help.

You should also make sure the cooler is mounted squarely over the CPU.

One of the biggest things is to make sure the case has good air flow. If air flow is restricted then the system is just recycling heated air and it won't keep cool well. The 8370 is 125 TDP and the cooler is 150 TDP rated, so it should do fine on the CPU. The applied thermal paste that comes on it should be ample, but I generally don't use it for any aftermarket coolers I've installed. I clean off the pre-applied thermal paste and then put on my own.

Are you making sure your not over doing or not applying enough thermal paste? Also making sure the heatsink is secure.

Sounds fine to me.

Well the Be Quiet! Pure Rock is meant to be 1 degree lower than the Hyper 212+/Evo. I never applied any thermal paste. Basically the heatsink came with a plastic lid from the back. Upon removing that cover there was already white thermal paste attached to the metal heatsink. So I didn't remove it or reapply any thermal paste.

I used the exact same cooler for my mums AMD FX-6300 Processor where max temps are 44 degrees at full stress testing even after hours of it being under full load and lowest idle temp 20 degrees. But using the same cooler for the FX-8370 causes the temps to go over 60+ degrees in only 2 minutes before I quickly stop the process! So I am sure the temps would go even higher if I leave the process on.

So I am confused whether these temps should be ok. Because I know safest max temp is 62 degrees for the FX-8370. Yet I was reading in many forums including PCPartPicker where a guy recommended it to me as he managed to overclock his FX 8350 to 4.5 GHz and still keep it cool. Yet I can't see my temps cool even with stock 4.0 GHz speed. So I don't understand what's going on.

However, one possibility I am suspecting is that during the installation the heatsink was moving several times. So I am wondering that maybe it scraped off the thermal paste a bit during the installation process. But that shouldn't really be responsible for causing this. I am still wondering whether this cooler is sufficient for the FX-8370 or whether I need watercooling. :S

@BLaZiNg_SPEED: You shouldn't NEED water cooling for any CPU unless you're doing extreme overclocking. While I wouldn't be worried unless the temp gets over 70C, I would suggest buying some good thermal paste and replacing what was on there and see what happens.

That 62C figure is just when the material of CPU will start to degrade over a certain random standard the manufacturer has placed. This basically means that it will decrease the life expectancy a little more than it working under that temp and the manufacturer feels that the amount of degradation at this temp is a jump big enough to take notice of, compared to previous values. Basically meaning that it needs to operate at or over those temps for prolonged periods of time for something to actually happen. I think this CPU will start to throttle down at 90C and even if it shots down, will most probably survive to live way more. You should only worry if you get 70C+ for prolonged periods of time. Your CPU won't die or suffer permanently by a spike of 62C+.

Anyways if you have the info and the parts, and yet sources still tell you that you should have other temps, then like others have suggested make sure you installed it correctly and that you're applying the right amount of paste.

Heatsinks come with garbage thermal paste. Buy some Arctic Silver 5, apply it and your temps will improve.
