Fixing Fanxiang S910Max 1TB overheating and speed drops in Hellblade 2
Going from buttery smooth to a literal slideshow in a high-fidelity scene is the worst feeling. The Fanxiang S910Max core temps were skyrocketing to 82℃ - 90℃ under load, triggering the hardware thermal wall and crashing my read speeds from 10,000MB/s down to about 1,500MB/s. I tried adding a dedicated spot fan in the case, but it only dropped the temp by 3 degrees; the throttling still hit like clockwork after an hour, which was honestly demoralizing. I ended up ripping off the stock heatsink, applying a high-conductivity phase-change pad, and cranking my front case fans up to 1,600 RPM. In HWMonitor, the peak temps were finally clamped at 62℃ - 68℃, and the read speed stayed rock steady. I actually messed up the first reinstall by over-tightening the screws, which slightly warped the PCB, but a bit of loosening sorted it out. Now the drive idles at 52℃ - 60℃. After a 5-hour stress test, no more drops, and memory temps stayed between 58℃ - 63℃.
