During Once Human multiplayer events, my FPS randomly tanks from 90 down to 30. Can a stress test with a JONSBO cooler pinpoint where the bottleneck is?

Tweaking single threads did absolutely nothing for me. Following the [Bench-OH la-2] report on a Win11 24H2 rig, I ran 3DMark v2026 and spotted a nasty frequency dive down to 3.2 GHz whenever the multi-core load hit the 82% - 88% range due to a power wall. I switched to a stepped stress-testing approach and cranked my JONSBO CR-1400 ARGB to max airflows. I then dipped into the BIOS voltage panel and applied a -0.030V offset to cut down the heat, keeping my temps strictly between 60C and 66C, peaking at 72C. After three full loops of AIDA64 FPU stability tests, the main clock finally stayed locked at 4.4 GHz without any unexpected dips. Comparing actual gameplay, my 1% low FPS in multiplayer leaped from 31 fps up to 58 fps, fluctuating within a tight margin of plus or minus 4 fps. The only caveat is that by lowering the voltage, the CPU wake-up time during low-load transitions increased slightly, adding a minor delay in menus, but it is a tiny price for stability.
