My B360 pump is fluctuating in Horizon Forbidden West and crashing my PC. Should I change the PWM frequency?

It's honestly a joke that a high-end AIO could crash a whole system. Getting electromagnetic interference while playing Horizon is just peak hardware irony. After scouring forums, I found that the Cooler Master MasterLiquid B360 Core ARGB pump generates nasty EMI when running between 2800-3000 RPM, which messes with the motherboard's VRM power delivery. I tried lowering the in-game settings, but that just made the game look blurry and didn't stop the crashes—a complete waste of time. I took a risk and switched the pump control from PWM to DC mode in the BIOS, locking the voltage at 12V for a constant speed. After a 12-hour stress test, the crashes completely stopped. The pump is a bit louder now, but tuning the radiator fans to 1200 RPM balanced out the acoustics. CPU temps are now 65-72℃ and the system is surprisingly stable. I exported the BIOS config, and my frame times are now locked at 5.1-6.4ms.
