Fixing thermal throttling on Fanxiang S910PRO 2TB in Far Cry 7?
Watching my frame rate plummet from 120 FPS down to 35 FPS was a nightmare; it felt like I was wading through thick mud. While the S910PRO's independent cache is great for response times, the power draw of PCIe 5.0 pushed core temps to a scorching 82-88℃ almost instantly, triggering a hard hardware throttle. My first instinct was to limit the interface to PCIe 4.0 in the BIOS. Sure, temps dropped to 60℃, but loading speeds tanked by 40%, which was a dealbreaker. I ended up swapping in a 2.0mm high-conductivity thermal pad and manually locked my bottom chassis fans to 1800 RPM. Monitoring via HWInfo, the drive temperature stayed clamped between 62-67℃, and the frame drops vanished entirely. I did have a moment of panic when I accidentally bent a gold finger contact during the heatsink install, causing the drive to disappear on reboot, but a quick pressure recalibration fixed it. Now, read speeds are consistently hitting 10000-11500MB/s. After a 4-hour stress test, there's no throttling, and memory temps are holding at 58-63℃.
