Optimizing ASRock A320M-HDV R4.0 power delivery for Warhammer?

Every time I rendered a full-map battle, the game would just vanish to the desktop without a word. The anxiety of losing a long campaign is real. The ASRock A320M-HDV VRMs were basically ovens, peaking at 105-112℃, which caused the CPU core voltage to tank by 0.14V. I first tried capping the CPU at 65W via software, but the game slowed down to a crawl—totally unacceptable. I ended up flipping my case fans to a forced exhaust setup and set Load-Line Calibration to Level 2 in the BIOS. Under OCCT stress tests, the VRM peak dropped from 112℃ to a manageable 86-91℃, and the crashes stopped entirely. I did notice some annoying resonance noise from the fans after the change, but some rubber dampeners fixed that. CPU cores are now stable at 75-81℃, and the BIOS profile confirms memory temps are holding at 58-63℃. It's a bit of a struggle on this old hardware, but it works.
