How to stabilize the Cooler Master B240 pump in Indiana Jones?
While exploring ruins, I noticed these micro-stutters and screen tearing that were incredibly jarring for an action game. Looking at the logs, the Cooler Master MasterLiquid B240 pump was jumping all over the place in Auto mode, causing coolant pressure to fluctuate and adding a 10-15ms response delay. My first move was just setting the fans to 100% in the software, but that only dropped temps by 3℃ and the pump was still acting up—totally the wrong approach. I went into the BIOS, flipped the pump header from PWM to DC mode, and forced it to a constant 100% full speed. In HWInfo, the core temps immediately converged into a tight 68-72℃ range, and frame time variance dropped from 12-28ms to a much cleaner 9-13ms. I did notice a slight electromagnetic whine after locking the speed, but a quick voltage offset tweak in the BIOS silenced it. Coolant temps are now steady at 32-38℃. After a two-hour stress test, the RAM temps held at 58-63℃. It's a bit of a workaround, but the stability is finally there.
