What are 4 pin fan headers called?
The standard 3- and 4-pin fan connectors are Molex KK series connectors. According to Wikipedia the part numbers for the 4-pin version are: Female Housing: 47054-1000. Female Contacts: 08-50-0114.
What are 4 pin headers for?
4-pin Fan. The 4-pin Fan power connector is found on motherboards within a computer case. This connector provides power to cooling fans and is typically used on the fan that cools the CPU.
Can you control 4 pin fans?
Thus, you CAN alter the speed of a 4-pin fan by changing the voltage supplied to its Pin #2. (Pin #1 is Ground.) The best way to do this is with a pre-engineered third-party fan speed controller because all the fancy design requirements have been done for you.
Can I plug 3 pin fan into 4 pin header?
1 Answer. 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.
Are 3 pin or 4 pin fans better?
The significant difference in practice is that 4-pin fans allow for RPM to change based on the need for cooling temperature, this reduces noise and power consumption. While 3-pin can control the voltage, but the voltage can’t turn to change the fan RPM at all and accurate as much as 4 pin fans.
Can I put a 3 pin fan?
Please Note: You can connect a 3 Pin Fan to a 3 Pin or 4 Pin header on the motherboard. The fan will function normally no matter type of fan header is used. 1. The fan connector will have two guides (1) and these will need to line up with the tab (2) that is on the motherboard fan header.
Does 4 pin mean PWM?
Speed Control
If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM. If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables.
