Why does my fan only have 3 pins?
Apparently a 3-pin fan can plug directly into a 4-pin socket. Two of the pins provide power to the fan, the 3rd provides an RPM pulse to the motherboard to read the speed. The 4th pin is for PWM speed control.
Can you control fans with 3 pins?
The speed of BOTH 3-pin and 4-pin fans can be controlled, but the method is different for the two types. For 3-pin fans, the connections to it are Ground to Pin #1, +VDC (varying) to Pin #2, and Speed signal on Pin #3.

When connected to 3-pin fan headers, the fan will run at full speed (unless the mainboard supports voltage based speed control).
Do PWM fans have 3 or 4 pins?
PWM fans are always 4 pin fan connectors. The additional wire has the ability to adjust the rotation speed depending on the temperature of the CPU.
Can a 3 pin fan be used for a 4 pin fan?
Chassis and CPU fans may use either 3-pin or 4-pin power connectors. 3-pin connectors are usually used for the smaller chassis fans with lower power consumption. 4-pin connectors are usually used by CPU fans with higher power consumption. Fans and on-board fan headers are backwards compatible.
