Fixing thermal throttling on Fanxiang S910PRO 2TB SSD?
The game would just go black during fast combo strings, and then I'd get a prompt saying the boot drive was missing—an absolutely miserable experience. Checking the logs, the Fanxiang S910PRO 2TB was hitting 88-92℃ under full PCIe 5.0 load, triggering the controller's thermal shutdown. I first tried capping the PCIe link to Gen4 in the BIOS, but while it dropped the temp by 10 degrees, my load times slowed by 40%, which was a complete dealbreaker. I ended up buying an M.2 active heatsink with a tiny fan and locked it at 3000 RPM, while also cranking up the intake on my front case fans. HWInfo showed the peak temps crashing from 92℃ down to a stable 55-62℃, and the drive hasn't disappeared once since. I actually messed up the install at first by over-tightening the screws, which slightly warped the PCB and made the drive undetectable until I backed off half a turn. Now speeds are rock steady above 10000MB/s with latency at 12-18ns. After a 12-hour stress test, the hardware is finally stable.
