Is the CPU's heatsink damaged or is the CPU itself faulty?
Hi Guys,
I recently assembled a new rig using an i7 7700K processor paired with a Cryorig H5 Universal heatsink for my first DIY build.
The challenge I encountered was that during a stress test, the CPU temperature surged from around 34°C to 70°C in just a few seconds, then gradually increased before settling into the low 80s. After stopping the test, the temperature dropped back down to 40°C within seconds. Because of these extreme temperatures, I’m now running the CPU without overclocking.
I’ve reinstalled the heatsink multiple times and applied fresh thermal paste each time, but the issue persists.
Is this typical behavior or should I expect a significant temperature drop within a minute or two? Would this indicate a heatsink problem or something else? Any guidance would be greatly appreciated. Thanks.
That's completely typical. You're handling around 100 watts through a space about the size of your pinky nail. It will likely heat up rapidly before gradually stabilizing as the nearby material warms, reaching its maximum power dissipation temperature. Because it's so compact, it should dissipate heat efficiently, almost as if it never ran for long.
The 7700k is extremely hot and requires high-quality cooling. The R1 model should suffice. I'm not sure how much the R5 differs from the R1.
