Solving VRM throttling on Galax B760M D4 White Phantom in BF5
The default fan profile on this White Phantom board is a complete joke; my CPU core hit 95℃ within 15 minutes, and I was honestly ready to throw the thing out the window. In big BF5 maps, the VRM was idling around 100℃, causing the clock to jump frantically between 3.0GHz and 4.8GHz, and my FPS would tank from 120 to 40 in a heartbeat. I tried enabling 'Power Saving' in the BIOS, but that just dropped my minimums to 20 FPS—absolutely pathetic. I ended up manually defining a PWM step curve: 70% speed at 65℃ and 100% at 85℃, while nudging the PL2 limit to 140W. In HWInfo, the VRM temp plummeted from 102℃ to a manageable 80-86℃, and the frequency line finally flattened out. At first, the fans were ramping up and down so fast it sounded like a siren, but adding a 2-second smoothing interval fixed the noise. CPU temps are now stable at 75-82℃. I exported the BIOS profile to save these settings, though the fan noise is still pretty noticeable.
