How to stop Fanxiang S790 4TB from overheating in Far Cry 6?
About three hours into the game, my stealth movements suddenly turned into a PowerPoint presentation before the whole system hard-locked and rebooted. It's honestly pathetic that a top-tier 4TB drive does this. The Fanxiang S790 is a PCIe 4.0 beast, but its core temps were hitting 82-88℃ under load, triggering the controller's thermal throttling and tanking my speeds from 7000MB/s down to a miserable 1200MB/s. I tried enabling power-saving mode in the BIOS to cool it down, but that was useless—it just increased load times by 30% without fixing the crashes. I eventually swapped in an M.2 heatsink with an active fan and pushed the fan curve to trigger at 80%. HWMonitor showed the core temps were finally clamped between 52-61℃, and the read/write lines flattened out. I actually messed up the install at first by over-tightening the screws, which slightly warped the PCB and made the drive disappear until I loosened them. Power draw stabilized at 7-10W. After a 4-hour stress test, the crashes stopped and memory temps stayed at 58-63℃.
