Optimizing Cooler Master B240 pump thresholds for Control 2
Seeing those CPU temps stay locked at 60℃ is honestly the most satisfying feeling ever. The Cooler Master B240 has great potential, but the stock 'Silent' mode sets the pump threshold at 65℃, which is way too high. During sudden load spikes, the core would jump to 88-92℃, causing those annoying micro-stutters. I tried the 'Max Performance' mode in BIOS, but the fan noise was like a jet engine taking off in my room—totally depressing. I manually dropped the pump start threshold to 50℃ and set a stepped fan curve to hit 1400 RPM at 70℃. The performance analyzer showed peak temps dropping from 91℃ to 68-74℃, and the physics simulations feel way faster. I had some weird pump bubbling at first, but adding a 3℃ hysteresis fixed it. Power is steady at 140 Watts, and frame times are locked at 5.1-6.4ms.
