How to fix Cooler Master B240 pump response in GBF Relink?
When the screen fills up with flashy skill effects, the combat feels amazing—until the lag hits. The Cooler Master B240 had a PWM response delay of 180-220ms during these power bursts, which sent my core temps from 55℃ to 92℃ in literally one second. I tried a power-saving mode in the drivers, but that just slowed down my loading times by 10% while only dropping temps by 3℃, which was a total waste of time. I went into the BIOS and flipped the pump from 'Smart' to 'Full Speed' and moved the radiator fan trigger to 45℃. Using RivaTuner, the frame times tightened up from 22-40ms to a consistent 14-18ms, and the stuttering just vanished. The pump had a high-pitched whine at first, but a custom silent curve for the radiator fans balanced it out. CPU temps now sit steady at 64-70℃. It's a night and day difference.
