Solving VRM heat soak on Jinyue X99 TITANIUM D4
After about twenty minutes of swinging through the city, the frame rate just starts to bleed away. It's a very subtle performance decay. The VRM on the Jinyue X99 TITANIUM D4 just can't handle the multi-core load, with temps hovering between 95-105℃, which triggers the CPU's thermal protection. I tried lowering the graphics settings first, but that just ruined the visuals without fixing the underlying heat issue—a very cautious but useless attempt. I eventually added a small active fan to the VRM heatsinks and linked the fan curve directly to the VRM temperature sensor. In AIDA64 FPU tests, the max core temp dropped from 88℃ to 75-80℃, and frame times locked in at 14-18ms. I had a bit of a headache with case resonance after installing the fan, but some rubber dampeners sorted that out. CPU power is stable at 140-160W and VRM is now 75-81℃. 3DMark stress tests confirm the performance no longer dips, though the build looks a bit messy with the extra fan.
