Unusually High CPU Temps

Matt Clatworthy · Apr 10, 2013

Hello,

I just built this PC:

Intel 3930k
Sabertooth X79 Mobo
32GB Vengence 1600Mhz
Corsair H100i Cooler

And I'm running everything at stock speeds, except I loaded the RAM XMP profile so it runs at 1600 Mhz

and when I am rendering something, within 15 seconds, Core Temp says the processor is at 78 deg C

I am ideling at about 38-42 C

Anyone know why this would happen?

I tightened down the CPU block very tight, so I know that is snug on the processor....

Matt Clatworthy :

did you apply thermal paste between the heat sink and the CPU?

Matt Clatworthy · Apr 10, 2013

The H100i had thermal paste pre-applied

Hi,

How did you set your FAN rpm's?

Matt Clatworthy · Apr 10, 2013

I have them linked to CorsairLink.... and they are going at max speed when its hitting these speeds

I guess my only option is to get new thermal paste and re-set the block... ugh

Do that

What is your Ambient (room) temperature? Idle temperatures are of little concern, but Load temperatures are extremely important. Please run Prime95 Small FFT's for 10 minutes, then post you Core temperatures and Ambient temperature.

Did you clean the processor IHS with isoprypol alcohol and a lint-free cloth?

CompuTronix :

Ambient Temp is about 20 C

I ran the Small FFT test.... and within 20 seconds it was at 78 C without any chance of stopping to rise, so I stopped the test....

About 3 days ago I could run Prime95 for 30 minutes and it stayed at 60-62 C .... but I don't know what could of changed....

I tried overclocking the CPU about 2 days ago... but decided to return to default (I reset the cosmos)

Thats another thing that was odd.... when I opened the CPU box, the cpu looked like it had fingerprints on it (the box was sealed though)

So I cleaned it with alcohol and a lint-free cloth...

Tap the radiator and pump a few times with the handle end of a screwdriver (while the computer is running, so the pump is working), not too hard. Sometimes air can be in the system which can cause reduced cooler - just like when you have an air lock in your cars cooling system.

Also running it with the case on its side for a few minutes, then running it standing up can help clear any air bubbles.

Try removing the H100i and wiping it and the IHS clean, apply thermal paste, and reseat everything.

Thanks, I'll try this when i get home from work
