How to fix VRM overheating and power limits on Biostar H310MHD3?
The moment I started cranking out defensive walls, my frame rate tanked from 120 FPS down to 45 FPS, which was a total nightmare. The Biostar H310MHD3 has zero heatsinks on the VRMs, and HWiNFO showed temperatures spiking between 92°C - 98°C, triggering a hard throttle. I first tried the High Performance power plan in Windows, but that just made the CPU frequencies swing wilder and pushed temps to 100°C, causing an instant system freeze. It was a wake-up call that pumping more voltage into a hot board is a recipe for disaster. I ended up rigging a small spot fan over the VRM area and manually locked the Long Duration Power Limit to 45W in the BIOS. In HWiNFO, the core clock stopped jumping between 2.8GHz - 3.6GHz and settled at a consistent 3.4GHz. I did hit a weird snag where the audio started crackling after the power limit tweak, but that vanished once I nudged the RAM frequency to 2400MHz. Now, CPU temps sit at 65°C - 72°C and the VRM zone dropped to 78°C - 84°C. After three full matches, the frames are smooth as butter at a locked 3.4GHz.
