How to fix thermal throttling on Samsung 9100 PRO in Tsushima?
While loading the massive open landscapes of Tsushima, my Samsung 9100 PRO's read/write speeds were jumping wildly between 10-12GB/s, causing those annoying micro-stutters. HWiNFO showed the controller temp spiking from 52℃ to 84℃ in seconds, triggering a brutal thermal throttle that left me totally confused. I first tried cranking up the case fans, but that only dropped the temp by 3℃—completely useless against the sheer heat of PCIe 5.0. I then dove into Power Options and set the hard disk to Maximum Performance, disabling all Link State Power Management. Surprisingly, that didn't fully kill the drops until I manually flashed the latest motherboard chipset drivers. Now the heatsink surface stays around 62-68℃ with positive air pressure in the chassis. Comparing IOPS response, random read latency dropped from 12-25ms down to a rock steady 4-7ms, and frame times are finally consistent at 5.1-6.4ms. It's a relief, but the drive still runs hot.
