Pulse Output

Will a 3 pin Fan/Heat sink work on a 4pin CPU?????????

If your first CPU Fan is 4 Pin, will a 3 pin CPU Fan work in a 4 pin slot?

Pin 4 is speed pulse output from the motherboard. A 3-pin fan, without this input, will work fine, and will simply run full-speed.

More information: 3-pin fan speed control is achieved by pulsing the fan's input power. If you've got a 4-pin fan installed, however, the BIOS is likely set to apply constant power and instead pulse pin 4, allowing the fan's internal circuitry to deal with cutting power to the rotor. Many BIOSs allow switching between 3-pin and 4-pin control mode; by choosing 3-pin, both fans should operate with correct speed throttling.
