WebFeb 19, 2014 · Feb 21, 2010. #1. I had to start a new thread because I couldn't update the old one. Here's the improved mosfet version of the 4pin pwm to 3pin fan circuit. This is closer to Intel's spec which allows for up to 5.25v pull-up and 5ma on the pwm pin. This is 5.15v and 1.2ma. Any logic-level n-channel mosfet capable of a few amps will work fine. WebMay 8, 2024 · 4 wire fans contain circuitry to regulate how much power is being delivered to the fan. You can think of it like a MOSFET with the PWM pin connected to the gate. When the PWM signal is HIGH, the MOSFET is on, current flows and the fan runs. When the PWM signal is low, the MOSFET is off and no current flows. This is typically done at around 25 ...
