Why is my i7 860 running so hot?

post #1 of 4
Thread Starter 
Alright, so after I completed my new PC I gave the old one to my GF.
The old PC has an i7 860 with the stock air cooler from Intel.

Now after setting up the PC at her home I did notice that the temps are way too high. I do not know for how long the temps have been so high:
Idle: around 60°C
Load: all cores at 97-99°C

I am not sure what is causing it. I do know that my old motherboard used to automatically overclock the cpu which caused my a lot of BSOD in the past. Took me some time to figure out that the motherboard was the bad guy here and turned off auto overclocking in the BIOS. Had no more BSOD from then on. However I could imagine that this overclocking may have damaged the CPU by raising electromigration.

At the moment my best guess is that the CPU cooler somehow has reduced or even no contact surface with the CPU anymore.

Have you experienced something like this in the past? What could be the reason?

I would make sure that the cooler is seated properly. I hate the post design on those stock Intel coolers, it's kindof easy not to get one all the way into the motherboard, leaving a gap across part of the CPU. When you pull it, also check the spread of the thermal paste, make sure it's even.

After opening the case and realizing that the cooler was full of dust, I removed it, cleaned it and put a new intel stock cooler that I had laying around. After this the processor ran cool again smile.gif

Thanks for your help

We need to keep our systems clean. It doesn't take much dust to effect cooling ability.
