Deep dive into bottlenecking World of Warcraft on WD Black SN850X 2TB
Following Test Plan #2026-WOW-BCLK on Win11 24H2 and driver 560.1, I used the WD Black SN850X (2TB, with heatsink). In a 40-man raid, 3DMark monitoring showed a textbook case of thermal throttling. Initial read/write speeds were erratic, swinging between 3000 MB/s and 6000 MB/s, with temperatures spiking to 82°C, causing frame times to go wild. My first instinct was to tweak software cache, which was a complete waste of time. The solution was in the BIOS Advanced Fan Control, where I bumped the M.2 zone curve from 40% to 75%. After synchronizing, the peak temperatures were capped between 68°C and 74°C. While a tiny a hiccup still persists during massive AOE spells, total stability improved by 20%. The relief of finally seeing a smooth raid is just incredible, honestly like a heavy weight lifted off my shoulders.
