How to fix CPU temp swings in CS2 with Jonsbo CR-1400 ARGB?
In the middle of a smoke-filled firefight, I noticed the frames were jumping around, which is a death sentence in a competitive shooter. The Jonsbo CR-1400 ARGB White Edition just doesn't have the thermal mass to handle aggressive boosting, causing the CPU to bounce between 85-92℃ and triggering frequency shifts. I tried disabling Core Boost in the OS, but while temps dropped to 70℃, my 1% lows tanked from 140 to 110 FPS, which made me very nervous about losing performance. I went into the BIOS, navigated to Advanced Voltage Settings, set a voltage offset of -0.05V, and tweaked the fan curve to hit 80% speed at 65℃. HWMonitor shows the temps are now stable at 74-79℃, and the frame time variance shrunk from 5-12ms down to 3-6ms. I tried -0.08V, but the system BSOD'd the moment I launched the game, so I backed it off to -0.05V. CPU now sits at 76-81℃ with fans at 1500 RPM. The stuttering is gone, and the stability is finally verified.
