Why does my Onda A520-VH-W trigger VRM overheating and clock drops during jungle fights in Crysis?

Dealing with the dense vegetation and lighting in this game was a nightmare for my motherboard's power delivery. I noticed the VRM temps swinging wildly between 95°C - 105°C, which sent my CPU clocks diving from 4.2GHz down to 2.8GHz instantly—absolutely lethal during a firefight. At first, I tried blasting the case with more fans, but since the heatsinks are tiny, it only dropped the temp by 2°C - 3°C. It felt like a hardware design flaw. I eventually dove into the BIOS, manually capped the CPU PPT at 65W, and shortened the fan response delay to 0.5s. Monitoring via HWiNFO showed the VRM temps finally settling into a stable 82°C - 88°C range, and the frame drops basically vanished. Interestingly, the initial power cap added about 4s to my load times until I nudged the RAM to 3200MHz to balance things out. Now, CPU cores stay between 74°C - 80°C. Stress tests confirm no more emergency throttling, with fans humming steadily at 1400-1600RPM.
