Yes, you can; most 3-pin header motherboards let you work by connecting only 3 pins of the fan. In fact, the 4th pin is only for PWM.
Can a CPU fan be 3-pin?
1. The fan connector has two guides (1) and must align with tab (2) located on the fan header on the system board. Note: You can connect a 3-pin fan to a 3-pin or 4-pin header on the motherboard. The fan will operate normally regardless of the type of fan head being used.
Can I connect a 3-pin CPU fan to a 4-pin?
1 Answer. Apparently, a 3-pin fan can be plugged directly into a 4-pin outlet. Two pins supply power to the fan, and the 3rd provides an RPM pulse to the motherboard to read the speed. The 4th pin is for PWM speed control.
Can I connect a 3-pin case fan to a 4-pin motherboard?
They are both compatible. Even if you put a 3-pin fan in a 4-pin motherboard slot, you can still control the fan speed on any motherboard you have. Just slide the 3-pin and leave the extra pin. Don’t do it backward; you will see a guide in the plug and motherboard socket.
Can you connect a 3-pin RGB to a 4-pin?
You can put a 3-pin in a 4-pin header for fans, but not ARGB. That is not possible. 3-pin ARGB headers are 5V with a 5V pin, a single data pin, a blank, and a ground pin. 4-pin RGB headers are 12V with 12V, red, blue and green pins. Inserting an ARGB strip into a non-ARGB header will blow out the strip.
Can fans with 3 pins be controlled?
The speed of BOTH 3-pin and 4-pin fans can be controlled, but the method differs for the two types. For 3-pin fans, the connections are ground to pin #1, +VDC (varying) to pin #2, and speed signal to pin #3.
Do 3-pin fans run at full speed?
When connected to 3-pin fan headers, the fan will run at full speed (unless the motherboard supports voltage-based speed control).
Can 3-pin fans be PWM?
Pulse width modulation (PWM) fans are DC fans with an extra wire for PWM. PWM fans are 4-pin fans where the fourth wire sends a PWM signal to the fan motor. The PWM signal is the control input of the PWM fan. PWM fans or 4-pin fans. DC Fan PWM Fan 3 Pin Fan 4 Pin Fan Voltage Control PWM Control.
What is the difference between a 3-pin and a 4-pin fan?
The big difference in practice is that 4-pin fans allow the speed to change based on the need for cooling temperature, reducing noise and power consumption. While 3-pin can control the voltage but cannot rotate it to adjust the fan speed, it is as accurate as 4-pin fans.
Are fan splitters safe?
You can safely use a fan splitter if the fans you connect are not drawing more current than the motherboard header supplies.
Can I connect a 3-wire fan to a 2-wire connector?
What does the CPU choose?
What is CPU OPT (CPU_OPT)? CPU_OPT, which stands for “CPU Optional”, is usually used if you have more than one fan on your cooler/radiator and need an outlet somewhere. It’s basically CPU_FAN without the “don’t boot if nothing is plugged in” part.
What does VDG mean on the motherboard?
The VDG is for some of the Gigabyte and Aorus motherboards that only use the 3-pin connection. Other brands used the 4-pin connector, and Gigabyte switched to that style on the more recent boards.
How many pins is Argb?
ARGB has 3 pins, but some motherboards, e.g., Gigabyte, have 4 pin connectors with one plug missing.
Is Argb a 5v or 12v?
The LED architecture differs with different types of LEDs, so they are fully compatible. ARGB, or Addressable RGB, uses 5 volts to power itself and has an address color processor connected to each LED. 12v is not addressable but follows the color currently displayed on the bus.
Can you connect 3 fans to the motherboard?
The female end of the Fan Hub connects to the motherboard, which then branches into several male headers to which you can link fans. A Fan Hub can typically connect up to 10 fans, either 3 or 4-pin PWM or DC fans.
How do you slow down a 3-pin fan?
If all the headers on your mb are three pins, the cheaper way is to put a resistor cable on the fan if you want to slow down. There calling 5v/7/12v fan cables. You can lower the 12v and slow down the fan. You must adjust the voltage with a fan controller to your three-pole fans.
How do I control the fan speed on my motherboard?
Use the arrow keys on your keyboard to scroll through the BIOS menu to the “Monitor”, “Status,” or another submenu of the same name (this will also vary slightly by manufacturer). Select the “Fan Speed Control” option from the submenu to access the fan controls.
Is it bad to run fans at full speed?
Running the fans at full speed is better for your other components, as it keeps them cooler. However, it can shorten the fans’ life, especially if they are plain bearings.
How does a 3-wire computer fan work?
A 3-wire fan has power, ground, and a tachymetric (“tach”) output, which provides a signal at a frequency proportional to speed. The tachometer signal indicates whether the fan is spinning and how fast it is spinning. A 4-wire fan has power, ground, a tach output, and a PWM drive input.
