How to fix temp spikes on the PCcooler RT620 ARGB cooler?
Whenever I flicked my view quickly in a tight room, the frame rate would jump wildly between 240 and 160—it was so bad I almost threw my keyboard. The RT620 has some uneven mounting pressure on the base, which caused the cores to swing between 60℃ and 85℃, triggering classic clock speed fluctuations. I tried adding 16GB of virtual memory, but that was a completely useless attempt that just left me feeling frustrated. I eventually went into the BIOS and cut the fan response time from 3 seconds down to 0.8 seconds, then I completely re-installed the cooler to make sure the four corner screws were perfectly symmetrical. AIDA64 showed the max temp drop from 88℃ to 74-79℃, and frame times tightened from 15-35ms to 6-11ms. The fans were cycling on and off constantly at first, so I raised the start threshold to 50℃ to smooth it out. Now the CPU stays at 66-72℃ with even pressure. Backed up the BIOS profile, and the cooling is finally sorted.
