How to fix Fanxiang S910PRO 2TB stuttering in Spider-Man 2?
When tearing through downtown NYC, the Fanxiang S910PRO 2TB's massive cache helps with random I/O, but the power draw of PCIe 5.0 is a nightmare, pushing the controller temps up to 82-88℃. This triggers a thermal throttle that tanks sequential reads from 10,000MB/s down to around 2,500MB/s, causing those jarring loading freezes. I initially tried disabling the write cache in Windows, but that was a total waste of time—it actually added 3 seconds to load times and made the frame drops worse, which left me completely baffled. I eventually fixed it by mounting an active cooling fan to blow directly onto the M.2 heatsink and setting the 'Turn off hard disk after' option to 'Never' in the Windows Power Plan. Checking HWiNFO, the controller temp dropped from 85℃ to a much safer 58-64℃, and the read/write curves stopped spiking and turned into flat lines. I actually struggled at first because some messy cables were blocking the airflow and causing heat pockets, but once I tidied the wiring and angled the fan correctly, it finally clicked. Now the drive sits steady at 62℃ with response times between 0.1-0.3ms. I ran several CrystalDiskMark passes to confirm the throttling is gone, and the settings are locked in.
