How many fans can a motherboard support?
Most motherboard headers will provide 1 A, so do not connect more than 4 fans to one header. Some motherboards have headers that can provide more (e.g., mine do 2 A) so you could attach more.

Do 2 pin fans run at full speed?
All fans in a computer are designed for max 12 VDC supply. A 2-pin fan generally has on the end of its wires a male 4-pin Molex connector, but only 2 pins are used. That mates with a power supply connector directly from the PSU. Done that way, it always runs at full speed.
Can 2 pins power a 3 pin fan?
Splendid. 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.
Can I plug a 3 pin fan into a 4-pin?
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 120mm or 140mm fans better?
The 120mm fans are the standard fans in most PCs. They boast several impressive features, including noise levels many users would consider acceptable. However, the 140mm fans sleek performance makes it noteworthy. With better noise levels and airflow, the 140mm would be more superior.
Is 2 fans enough for a gaming PC?
It depends on the hardware and layout of the case, but in general a single intake fan is enough for a general-use computer. For a low-end gaming PC, 1/1 is fine, 2/1 or 3/1 for higher-power hardware.
Can 2 pin fans be controlled?
Any DC fan (or any DC motor), even 2 pin, can be controlled by pulse width modulation.
Why do some fans have 3 wires?
The third wire gives your computer a measure of control over that. It reports the speed of the fan back to the computers processors, which allows the motherboard to control the speed of the fan by raising the voltage – and speeding the fan – when the extra cooling is required, and lowering it when its not needed.
How does a 3 wire fan work?
In a 3-wire fan, first two wires are the power supply wires of the fan. The third wire, comes directly from the output of the built-in Hall Sensor chip generates output pulses during the fan rotation. With the help of this third wire, a monitoring circuit can see the rotation.
