Why is my Cooler Master B240 struggling in Hellblade 2?
When hitting those high-fidelity psychological horror scenes, I noticed these tiny, annoying tears in the image that just killed the immersion. Checking HWiNFO, the Cooler Master MasterLiquid B240 pump was jumping wildly between 2200-2500 RPM, which sent my CPU cores swinging from 72-88℃ and triggered constant clock speed shifts. I tried slamming the pump to full speed in the BIOS, but while it shaved off 3℃, the high-frequency resonance made my entire chassis vibrate like a lawnmower—totally unusable. I eventually dove into the motherboard control panel, slashed the fan response time from 3 seconds down to 0.5 seconds, and set a hard trigger for 80% speed at 65℃. In HWiNFO, the core temps finally settled into a tight 62-68℃ range, and my frame times dropped from a messy 14-22ms to a smooth 9-13ms. I did hit a snag where the fans kept cycling on and off during low loads, but adding a 5℃ hysteresis window fixed that. With coolant temps sitting at 31-35℃, the thermal performance is finally peaked. I saved the PWM profile via the system tool, and the 9-13ms frame time is now rock solid.
