CPU operates at a higher than usual temperature of 4.1 MHz.
Hi everyone.
I recently upgraded my CPU (i5 4690k) and began with a cautious approach. I reached 4.1 MHz where the system remained stable, but I can't push further since my CPU temperature is already at 80 degrees Celsius during stress tests with Prime95. While putting the computer together, I wondered if I might have applied too much thermal paste, though I decided to continue anyway (possibly not the right decision). Could this issue be linked to excessive paste, or is it a problem with the CPU itself? - Thanks in advance!
Reapplying thermal paste is a simple solution and makes sense. Turn off the device, unplug it, and remove the EVO. Remove the processor and clean both surfaces with Isopropyl Alcohol—aim for a concentration of 50% or higher. Just apply enough paste to cover the processor evenly.
Having too much thermal paste can be problematic. It's better to eliminate all the existing paste and apply fresh one.

Yes, using too much thermal paste is harmful. It blocks heat from reaching the heatpipes on the CPU cooler. Revert the excess paste and apply a small amount of fresh thermal paste to the CPU.
My experience using Prime95 beyond version 26.6 and newer Intel chips (like Sandy Bridge and above) shows the AVX instructions it relies on cause more heat than usual.
Expecting a temperature rise of 80°C during stress tests—often after a few minutes—is normal, even with proper thermal paste.
If you're concerned about stability, consider switching to real games such as Battlefield 3/4 or GTA V, or try Folding@Home via Chrome.
My 4790k reaches 95°C with minimal FFTs... eeek!
