Dealing with thermal throttling on Fanxiang S910Max 2TB PCIe 5.0
There is nothing more frustrating than a lightning-fast loading bar suddenly hitting a brick wall, especially with 4K textures. The Fanxiang S910Max 2TB core temps were skyrocketing to 82-88℃, triggering a hardware-level thermal throttle that tanked the bandwidth from 10GB/s down to a pathetic 2GB/s. I first tried disabling the Windows Indexing service, but it did absolutely nothing for the read speeds and just added unnecessary CPU overhead—a total waste of time. I eventually went into the BIOS to redefine the M.2 dedicated fan thresholds, moving the trigger point from 60℃ down to 45℃, and swapped the thermal pads for ones with higher conductivity. Monitoring with HWMonitor showed the peak temps were suppressed to 62-68℃, and the read/write curves flattened out. At first, the fan noise at full tilt was absolutely deafening, but switching to a stepped curve finally balanced the noise and performance. Idle temps now sit at 38-42℃. I verified the thermal wall was gone via the motherboard software, with memory temps holding at 58-63℃.
