Eliminating VRM heat soak on Onda B760ITX-B4
It's honestly ridiculous—I'm playing a gorgeous game and my motherboard is treating my clock speeds like a roller coaster, turning the game into a slideshow. The VRM heatsinks on the Onda B760ITX-B4 were hitting 90-102℃, causing the CPU to dive from 4.5GHz to 2.2GHz in a split second. I tried lowering the graphics settings, but that just made the game look like a pixelated mess while barely giving me 10 more FPS—it was a pathetic attempt. I ended up stripping the cooler, reapplying high-grade thermal paste, and zip-tying a 40mm fan directly over the VRM area for forced convection. In AIDA64, the VRM temps plummeted from 102℃ to a manageable 78-84℃, and my FPS stabilized from a wild 30-60 range to a steady 55-60. I actually shorted the board and triggered a reboot because of messy wiring during the fan install, but once I tidied the cables, it was golden. CPU power now sits at 100-120W with VRM at 80-86℃. I exported the logs and the fan speed is locked at 1400-1600 RPM.
