Why is my Cooler Master B240 failing in Metro Awakening?
It's a joke—I bought a liquid cooler and I'm still getting stutters in firefights. The Cooler Master B240's default curve is way too lazy; it takes 6 seconds for fans to ramp from 600 to 1500 RPM, letting the core spike to 88℃ and throttle instantly. I tried the motherboard's 'Aggressive' mode, but that just turned my room into a wind tunnel without fixing the drops. Pure insanity. I ended up manually defining the trigger points: 55℃ for start and 70℃ for full blast, while killing all power-saving features. RivaTuner showed my frame times dropping from a messy 12-38ms range down to a tight 7-12ms. I had some annoying vibration noise at first because the fans kicked in too hard, but moving the fan mounts fixed it. CPU temps now hover at 65-71℃ with fans at 1200 RPM. I exported the logs and confirmed the fan speed is rock solid at 1400-1600 RPM.
