Gears 5 is dropping frames during heavy effects on my Biostar B550MH. Can a power limit fix this?

Every time a massive explosion went off, my FPS would dive from 70 down to 25—it was absolutely pathetic. The Biostar B550MH has tiny VRM heatsinks that just can't cope; temps were hitting 104℃, triggering a brutal throttle that crashed my CPU from 4.4GHz to 2.1GHz. It was a total hardware bottleneck. I tried the 'Enhanced Cooling' mode in BIOS, but since there's no actual surface area to dissipate heat, the fans just screamed while the temps stayed high. I ended up buying a cheap 80mm fan and pointed it directly at the VRMs, then capped the PL1 power limit to 65W in the BIOS. CPU-Z showed VRM temps drop from 106℃ to 84-88℃, with clock fluctuations staying within 0.2GHz. I lost about 7% single-core performance, but because the massive frame drops disappeared, the game actually feels way smoother. CPU stays at 72-78℃. Backed up this compromise config via the BIOS tool.
