Solving Fanxiang S910Max 1TB overheating and throttling?
The read/write speeds were swinging wildly around 3500MB/s, and the resulting stutter during scene loads was absolutely brutal. Looking back at my build, the stock heatsink on the Fanxiang S910Max just couldn't handle PCIe 5.0 full load, with temps screaming up to 85-90℃ and triggering aggressive throttling. My first instinct was to drop the PCIe link speed to Gen 4 in the BIOS. While that knocked 12℃ off the temp, my sequential reads tanked from 10000MB/s to 6500MB/s, which was a total dealbreaker. I ended up ripping off the stock cooler and swapping it for a 15W/mK phase-change thermal pad, then cranked my front case fans up to 1600 RPM. During an AIDA64 stress test, the peak temp plummeted from 90℃ to a manageable 65-71℃, and speeds finally locked in above 10000MB/s. Early on, the fan noise was loud enough to be distracting, but I balanced it out by setting a silent curve for everything under 60℃. The drive load stays around 88% and heat dissipates instantly. Monitoring software confirms the thermal throttling is gone. Issue resolved.
