A four pin connector is a little different than the three pin connector since it has the extra (fourth) wire used for controlling and sending signals to the fan, which likely has a chip on it that tells it to slow down or speed up (in addition to the other wires the three pin connector has).20 jun 2017
Can you control a 4 pin fan?
In addition to the power, ground, and tach signal, 4-wire fans have a PWM input, which is used to control the speed of the fan. ... Another advantage of 4-wire fans is that the fan speed can be controlled at speeds as low as 10% of the fan's full speed.
How many 4 pins does a motherboard have?
Usually motherboards should have at least 1-2 4 pin connectors for the CPU, as well as a couple of 3 or 4 pin connectors for case fans.17 sept 2015
Does any 4 pin connector work for fans?

Can a 4pin fan work 3 pin connector?
You can plug in the 4 pin fan with your 3 pin motherboard. The fan will simply run at full speed. The 4-pin fans are often referred to as PWM fans, because the 4th connector is the what the motherboard or fan controller uses to modulate the power allowing the speeds to change.15 oct 2013
Can I use PWM fan without PWM?
If no PWM signal is present, almost all fans will work on 100% of power, while most pumps used in water cooling will operate at some medium speed. Meaning, if you want to run the pump on full power, you need to hook it up to a PWM signal that is set on 100% duty cycle.14 jul 2016
Can you control fan speed with 3 pin?
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 #3.1 ene 2017
Are PC fans 3 or 4 pin?

Do 3 pin case fans work on 4 pin connectors?
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.
Can I put a 3 pin fan in a 4 pin slot?
The 4th pin allows PWM controlled speed, 3 pins will plug into 4 pin sockets but control signal won't be sent and fans will run at max. 3 pin fans don't have PWM controlled speed. So it's fine.31 dic 2011
