How to stop Samsung 9100 PRO PCIe 5.0 from overheating?
I finally got to experience PCIe 5.0 speeds, but the heat is insane—it's like having a small space heater sitting on my motherboard. The Samsung 9100 PRO core temps shot up to 82-88℃ under load, triggering the motherboard's thermal throttling and crashing my random read speeds from 12000MB/s down to 3000MB/s. Consequently, my FPS tanked from 110 down to 45. I first tried capping the PCIe link to 4.0 in the BIOS; temps dropped to 60℃, but loading times nearly doubled, which was a totally unacceptable trade-off. I ended up reinstalling the stock heatsink and adding a 40mm micro-fan blowing directly on it, while setting the M.2 fan curve to 'Aggressive' in the BIOS. HWInfo shows the drive now peaks at 62-68℃, and the speeds are rock steady. I had some annoying resonance noise right after installing the fan, but replacing the rubber pads solved it. Idle temps are now 38-42℃, and the benchmark curves are back to peak performance.
