How to stop CPU throttling on ASUS B760M TUF Gaming?
During heavy physics calculations, I noticed my CPU core clock suddenly plummet from 5.0GHz to 3.2GHz, which felt like a massive slide-show whenever I turned the camera quickly. The VRMs on the ASUS B760M TUF were hitting 95-102℃ during transient power peaks, triggering the motherboard's thermal protection. I first tried capping the CPU power limit to 125W in the BIOS; temps dropped to 80℃, but the rendering speed took a hit, which just ruined the experience. I eventually rigged a small 12cm fan to blow directly onto the VRM heatsinks and set the VRM fan curve to full speed. HWInfo showed the power delivery temps stabilizing between 78-84℃, and the clock speeds stopped diving. I had a minor scare where the RAM wasn't detected on the first boot because of the new fan cables, but a quick cable tidy fixed it. CPU temps are now 65-72℃. After a 3-hour stress test, the clocks are stable and VRM temps are locked at 78-84℃.
