How to stop VRM throttling on Biostar B650MT in Orion?
It was ridiculous—in the middle of a high-action cyberpunk scene, my CPU would start throttling because the motherboard VRMs were cooking. The Biostar B650MT's heatsinks were hitting 90-96°C, causing my clock speeds to plummet from 4.7GHz to 2.4GHz instantly. I tried the 'amateur' fix of ripping the side panel off my case, but that only dropped temps by 4°C and just let dust fly everywhere while the fans still sounded like a jet engine. Instead, I overhauled my airflow, added two 120mm exhaust fans at the top, and set a custom fan curve to hit 100% speed at 70°C. HWInfo now shows the VRM staying between 76°C and 82°C, so the clocks don't tank anymore. The full-speed fans were deafening at first, so I had to set up a stepped curve to keep my sanity. CPU temps are now 65-72°C, and my logs show fans stable at 1400-1600RPM.
