How to fix uneven mounting pressure on Jonsbo CR-1400 ARGB?
Those sudden hitches in the frame rate turned out to be a nightmare of uneven CPU heat distribution. I saw a delta of 18°C between the hottest and coldest cores, which triggered local frequency limits. I tried ramping up the fans, but that one core stayed pegged at 91-95°C. The sheer frustration led me to rip the cooler off and check the contact plate. The thermal paste was smeared unevenly—classic case of offset mounting pressure. I re-installed it, tightened the screws in a cross pattern, and swapped to a high-conductivity paste, bringing the core delta down to 6-9°C. Interestingly, the temps didn't drop much until I increased the intake on my front case fans, finally pulling peaks down to 76-82°C. Now the cores sit at 64-70°C and the heatsink feels just warm to the touch. AIDA64 stress tests show my 1% lows jumped from 35 to 52 FPS, with memory temps holding at 58-63°C.
