Fixing thermal throttling on Samsung 9100 PRO 4TB?
During these massive Boss fights, the drive temps would hit the 85℃ ceiling and then the system would just drop the drive entirely—it was terrifying. The PCIe 5.0 mode on the Samsung 9100 PRO 4TB pulls way too much power, causing the controller to trigger thermal protection during heavy data bursts. I tried lowering the graphics settings to reduce the load, but while the FPS went up, the drive still vanished, which was a total waste of time. I ended up buying an M.2 active heatsink with a tiny fan and forced the PCIe link to Gen4 in the BIOS to keep the heat in check. Monitoring with HWInfo, the peak temp plummeted from 85℃ to a manageable 52-60℃, and the disconnects stopped completely. I actually had a clumsy moment where the fan cable blocked my GPU fan, making my graphics card overheat until I rerouted the cables. Read/write speeds are now around 6000-7000MB/s—I lost some peak speed, but I'll take stability over a crash any day.
