Fixing Great Wall GW3300 thermal stability in Minecraft
The game would just vanish to the desktop after 30 minutes without warning, which was incredibly stressful. Monitoring revealed the Great Wall GW3300 controller was hitting 85-91℃ during heavy ray-tracing write operations, triggering a hardware thermal shutdown. I tried adding a side intake fan to the case, but it only dropped the temp by 2℃, leaving the SSD core stuck above 82℃—completely useless. I then went into Device Manager and shifted the disk write caching policy from 'Maximum' to 'Balanced' and set the PCIe power management to 'Maximum Performance'. In OCCT stress tests, the controller temp dropped to 62-68℃, and the crashes stopped entirely. I noticed load times increased by about 2 seconds after the cache change, but enabling Re-Size BAR brought the performance back. Drive temps are now steady at 55-61℃. Five hours of gameplay without a single crash.
