How to fix VRM overheating on Colorful CVN B760M?
Right as I trigger a big ability, the frame rate takes a massive 0.2-second dive. It's a really jarring feeling that gets worse the longer the session goes. The VRM modules on the Colorful CVN B760M were spiking between 95-102℃ under heavy CPU load, triggering thermal throttling. I tried enabling 'Power Saving' in the BIOS, but that just tanked my CPU clock to 3.0GHz and made the lag even worse—clearly, this was a physical cooling issue. I installed two 12cm exhaust fans at the top and manually capped the PL1 power limit to 125W. In RTSS, the frame time swings went from 14-38ms down to a stable 11-16ms. I actually installed the fans backward at first, which just pushed hot air back in, but once I flipped them, the temps plummeted. VRMs now sit at 78-84℃, and the GPU stays cool at 64-70℃.
