Can you run a 3-wire fan with 2 wires?
The 3 Pin fan will fit onto the 2 pin you just need to match the holes and the pins and see which two contacts make the fan function.
Will a 3 pin fan work in a 2 pin slot?
It’s safe as long as the rated Amperage for both fans added doesn’t exceed the max ouput of the header slot. For example if the header was 1A(1000mA) and each fan was 300mA (2x300mA=600mA) you’re fine.
Why does a computer fan have 3 wires?
A 3-wire fan has power, ground, and a tachometric (“tach”) output, which provides a signal with frequency proportional to speed. A 4-wire fan has power, ground, a tach output, and a PWM-drive input. The tach signal indicates whether the fan is running and its rate of speed.
Can 2 pin fan connect to motherboard?
Just plug that connector into the far left pins on the CPU fan header on the motherboard. If you plug it in backwards, no harm done, it just won’t spin.
How do I wire 2 wires with 3 wires?

Can I put a 3 pin fan into a 4 pin header?
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. 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.
What are the three wires on a fan?
- Black wire is for the fan.
- Blue wire is for the lamp if one is included with the fan.
- White wire is neutral.
- Green wire is for the ground.
- Red wire is sometimes included and acts as a conductor to carry power to the light kit.
Can you control a 2 pin fan?
Any DC fan (or any DC motor), even 2 pin, can be controlled by pulse width modulation.
Where do you connect two pin fans?
How to convert 2 wire to 3 wire fan?
Solder a wire to the coil-wire and close up the fan again. Then solder a common purpose diode like the 1N4148 or 1N914 to the third wire with it’s kathode to the fan side, it’s anode is your third wire connection. Now take a 3 pins single in line (SIL) female header to replace the original 3 wire headers (Right Picture).
Is it possible to convert a 3 pin 40mm fan into a 2 pin fan?
1. Apply oil to the old fan 2. Somehow convert the new 3 pin fan into 2 pins 3. Purchase a new 2 pin 40mm fan for a better price than what’s available on ebay! [Jeez they cost close to $20 on there with shipping to Canada]
