After playing Dying Light 2 for a while, my ASRock B450M-HDV R4.0 starts dropping frames due to heat.

The parkour in this game looks amazing in 4K, but the sudden FPS drops are absolutely infuriating. The VRM heatsink on the ASRock B450M-HDV R4.0 just can't handle high-TDP CPUs, with temps spiking to 95-105℃ after an hour, triggering aggressive thermal throttling. I tried enabling 'Extreme Performance' in the BIOS, but the temps hit 110℃ and the whole system just rebooted—talk about a wake-up call. I ended up rigging a small 40mm fan to blow directly onto the VRMs and set a -0.05V undervolt curve in the BIOS. In my side-by-side tests, the core clock stayed locked at 4.2GHz without any dips. I previously tried lowering the CPU multiplier to save temps, but the FPS dropped to 40, which was totally unplayable. VRM temps now sit at 68-75℃. I switched the power mode to Balanced, and the fan stays around 1400-1600RPM.
