Optimizing pump response and locking RPM on MasterLiquid B240
The pump logic on this MasterLiquid B240 is basically on vacation; the CPU is practically cooking while the pump takes its sweet time ramping up. In Enshrouded's complex build areas, my CPU temp would jump from 60℃ to 92℃ in a single second, making the frame rate look like an EKG monitor. It was driving me insane. I tried the 'Aggressive' software mode, but the pump just sounded like a power drill without actually cooling the chip faster—totally pointless noise. I went straight into the BIOS, switched the pump header from Smart to Full Speed, and locked it at 4200 RPM to force the coolant to circulate. In the RTSS frame time graph, those jagged spikes vanished, and frame times flattened to 16-19ms. I did notice that idle water temps rose by about 2℃ after locking the speed, but that's a tiny price to pay for absolute stability under load. Peak CPU temps are now hard-capped between 78℃ - 83℃ with fans at 1400 RPM. I used a performance analyzer to export all the correlated temp and frame data.
