Fixing thermal spikes on Colorful CVN B760M FROZEN WIFI D5 V20
During intense team fights, I'd get these tiny, annoying hitches in the movement. Dota 2 isn't a CPU hog, but the default fan response on this board was way too slow before 60°C, causing the CPU to spike between 80-86°C and messing up the frame times. I tried limiting the CPU to 99% in Windows, but that just dropped my minimums from 130 FPS to 100 FPS—not a great trade. I went into the BIOS and slashed the fan response time from 2 seconds down to 0.5 seconds, and set a steep linear ramp between 60-80°C. RivaTuner showed the frame intervals tighten from 12-22ms down to 8-12ms. The fans did make a weird resonance noise at low loads initially, but setting a minimum floor of 800 RPM fixed that. Core temps are now a steady 60-66°C. 3DMark confirms zero drops now, with fans humming along at 1200-1400RPM.
