How to fix B360 Core pump instability in Resident Evil Village?
The optimization in this game is a disaster on some setups. My CPU had plenty of headroom, yet I was getting constant crashes on the Cooler Master B360 Core, which was just infuriating. It turned out the pump's PWM signal had compatibility issues with my old BIOS, causing the pump speed to swing wildly between 1800 and 2800 RPM during heavy data loads, which spiked core temps past 95℃ and crashed the system. I tried lowering all the graphics settings, but that didn't stop the crashes and just made loading take longer—a complete waste of time. I finally used the official tool to update the AIO firmware and forced the pump header to DC mode in the BIOS, locking it at 12V. In Event Viewer, the 0x0000007E error codes vanished, and I finally hit a five-hour session without a single crash. The pump made a weird screeching sound at startup after locking the voltage, but adjusting the radiator angle fixed the air bubbles. CPU temps are now 65-72℃, with coolant at 30-35℃. I saved these stability settings in a system snapshot, with coolant staying at 30-35℃.
