3930k thermal stability issues

post #1 of 4
Thread Starter 
When I first built my rig I could keep the temps stable under 60C at full load. Now about 5 months later When ever I put any real load on it the core temps skyrocket to 68C within about a half hour. So do I just need to replace the Paste or is there something else that I am missing? Additionally Intel states that the Tmax for the case is 66.8C but what is it for the cores?

I believe it's 98 C. Common practice is don't let it get above 80 C.

Dust is the most likely culprit. Then, i would say thermal paste. Sometimes after heating-cooling-heating-cooling-heating-cooling the heatsink needs to be re-seated.

Also, the temperature and relative humidity of your house can have a minor impact as well.

Ambient temps have a huge impact on load temps. 5 months ago, it was January/December, which is Winter. It's May, its much warmer now. Make sense to me that temps will go up, 5-10C isn't uncommon. Just think about the actual ambient temp difference in Kansas between January and May. I used to live in Wichita so I'm definitely aware of the temperature changes between Winter and Summer. Summer can be pretty damn hot and humid and winters can be blistering cold. I'd say a 8c increase in temps is perfectly normal.

The reason for that is probably higher ambient temperatures and dust inside your rig.

That said 68C is nothing to worry about.
