Prime95 CPU Temps seem high?

I am running an i5 3570k, and I downloaded the CPUID Hardware monitor and Prime95. I clicked the blend test for prime 95 and the CPU tempts are running at 60 degrees Celsius. This seems quite high doesn't it?

No overclocking at all yet.

noctua nh-d14 cooler
intel i5 3570k

Also: My bios also said my CPU temp was at ~30 degrees Celsius while idle at the bios screen.

30 is normal for the BIOS screen.

60 is also quite normal for IB. IB is known to run hotter due to their IHC not using a fluxless solder and instead using a TIM paste.

How long did you run the test for? If it was for 5 minutes i'd be worried - if it was for 1 hour - it should be good.

Also you should download the Intel Burn Test. Try that out and test your temperatures.

For intelburntest, under the standard test, I ran it 5 times, and core temps, according to Hwinfo(i got a diff sensor), shot up immediately to ~62 celsius and stayed there

For high, it shot up to ~ 64C and stayed there

for very high, it shot up to ~66C and stayed there

For all of these I am referring to the "CPU Package" temp

Those are fine, after all IB runs a bit hotter than SB. BTW Intel Burn In Test pushes your processor above Prime95, this is no where near real world usage so it is nothing to worry about.

It just seems like my temps shoot up immediately (for burn test) to the 60s. It's not really a slow buildup. Even prime95 seems to shoot pretty quickly up to ~60C.

This is because you are jumping from a 1-2% load to a 100% load!

All those tests stress the maximum? Even prime95 blend test?

IBT is basically the absolute maximum (for CPU), yes.

60c is very very nice indeed. 65c is ok and 70c-72c is the upper part of acceptable for a 100% stress test.

IBT is 100% test at normal, high, and very high? Or it just @ the maximum setting

100% is all of them, just different degrees of stress. Maximum is the absolute maximum, obviously.

There is no need to worry, your system is FINE.

So there's no need to run more tests? like overnight tests/etc? I plan on overclocking sooner or later. Also, Thanks for entertaining my paranoia fellas. :D

Run those test ONCE you have overclocked!

No, the only reason to run tests for that long is stability, and at stock, that's not a problem.
