Fixing M.2 thermal throttling on Colorful H610M-K M.2 V20
Trying to run a AAA title on this entry-level board is basically a stress test for the hardware's will to live. Because the Colorful H610M-K M.2 V20 lacks a native heatsink, my SSD was idling between 75 - 88℃, triggering a hardware-level speed limit. I tried switching the Windows power plan to 'Balanced', but the read speeds actually tanked from 3000MB/s to 1200MB/s—a complete waste of time. I ended up slapping on a 3mm pure copper heatsink and disabling PCIe Power Management in the BIOS. CrystalDiskMark showed random 4K reads climbing back up to 60 - 72MB/s. I actually over-tightened the screw and slightly warped the PCB, which was a scary moment, but a quick loosen fixed it. SSD temps are now a healthy 52 - 60℃. Exported the latency logs, and the fan is humming along at 1400 - 1600RPM.
