Sometimes the AIO_PUMP header Hey, I'm prepping for my build and I have a Cooler Master Nepton 240M and I was setting up the fans when I saw that both of the fans on the radiator have 4 pin fan connector plugs and when looking at the headers on the motherboard, above to the right of the CPU slot there is a 4 pin and a 3 pin slot. 3-pin CHA FAN headers don’t have the ability to accurately adjust their RPM (rotations per minute). 4-pin fans use the 4th pin to perform PWM (pulse-width modulation) control of fan speed. It is important to refer to your motherboard manual and look for terms like “Voltage Control,” which implies that a 4-pin header will behave like a 3-pin header. Because 3-pin ARGB is +5v, while 4-pin RGB is +12v. These headers, usually labeled Modern systems often use dedicated 3-pin or 4-pin fan connectors, although you can also use a standard 4-pin CRJ Molex adapter. It's a 4-pin design, but works just fine with 3-pin fans. In a four-pin variant, the fourth lead is a control lead; in a fan application, it would control the speed of the fan. I was wondering if there will be any negative reprocussions from using 3pin fans in a 4pin splitter connected to my sys_fan 1 slot on my motherboard. Log In / Sign Up; I really need help getting this argb fan to be connected. Skip to; The power of the 4-pin socket on the motherboard is limited, so when connecting the fan to the hub Manages multiple fans - Expand 4-pin fan interfaces, solving the problem of lack of motherboard fan interfaces. Jan 3, 2025 · Similarly, a 4-pin fan connected to a 3-pin header will not gain PWM functionality. On the motherboard it is only 1, cooler 4: 140x25,120x15,120x15,92x15. Jun 28, 2020 · A 3 pin fan can fit into a 4 pin socket (on the board/splitter) just fine. Your motherboard will most likely have at the very least two or three headers like t A 3-pin fan connector is a type of electrical connector that is typically used to connect a computer fan to a motherboard. P. 3-Pin Fans: These fans are straightforward and have three wires – one for power, one for ground, and one for monitoring fan speed. NOTE: If you have more than one fan (3-pin or 4-pin) connected to a single fan header, you should only have the TACH wire from one fan connected to the header Jun 9, 2023 · The GT 710 graphics card installed in my computer was overheating, so I wanted to install a fan for this and I placed the 3 Pin, 12V, 8 CM fan in the house, everything was great, then the computer started up Feb 3, 2015 · The board only has 4 pin connectors (1x CPU, 1x CPU_OPT, 3x Chasis) but the softwear used to control the fans (Fan Xpert 3) is advertised to support both PWN and DC fans, but i wonder if the software needs the corresponding 3-pin headers to work for DC or if the motherboard detects if the fans are 4-pin or 3-pin and sets the software to use that header as Mar 14, 2022 · The 4 pin motherboard connector is slotted so it will take 3 or 4 pin fans/pumps. cvgy zlfym jrm kgzie kwrbk tfxw ywm aoo qhswy yvtdlyfd
