Fixing single-core overheating on DeepCool AK620 White ARGB
During those long hauls in the wilderness, I noticed my CPU's second core was running 12℃ - 15℃ hotter than the others. This imbalance triggered a severe throttling mechanism once the load hit 70%, and the resulting stutter was absolutely brutal. I tried cranking the fans to 100%, but while overall temps dropped by 3℃, that single-core delta stayed above 10℃—software tweaks are useless when you have a physical mounting issue. I ripped off the DeepCool AK620 White ARGB and found the pre-applied paste was bunched up at the edges with tiny air bubbles in the center. I swapped it for high-conductivity liquid metal paste and used the cross-pattern tightening method to ensure the pressure was dead even. In AIDA64 stress tests, the peak temp plummeted from 95℃ to 78℃ - 82℃, with the delta narrowing to 3℃ - 5℃. I actually messed up the second install by over-tightening, which slightly warped the PCB and caused the system to lose some memory channels until I backed the screws off half a turn. Now the fans sit at about 32dB and the fins feel just warm. Real-time curves confirm the contact issue is dead and buried.
