How to optimize airflow for PCcooler RT620 in WoW?
In crowded hubs, my FPS would randomly dive from 100 to 60, which really killed the immersion, though pushing the hardware to its limit was kind of exciting. The PCcooler RT620 was hitting thermal saturation between 86-92℃, causing the clock speeds to jitter every 10ms. I tried the Windows power-saving mode, but that just capped me at 40 FPS—a totally useless fix that proved I needed a physical solution. I overhauled my case pressure, bumping the intake-to-exhaust ratio to 1.4x, and set the BIOS fans to full speed. Monitoring via RTSS, my temps dropped from 92℃ to a cool 68-74℃, and the stuttering vanished. I actually found a thick layer of dust in the top filters after the first tweak, and cleaning them gave me the final performance boost I needed. The CPU is now running great, with temps sitting comfortably between 62-68℃. It's a night and day difference in the main cities.
