4 Pin pwm connector

But nowadays, if you want to control the speed of your fans and pumps, PWM control is the way to go. Every mainstream motherboard that leaves the factory today is equipped with at least one - pin PWM header. The extension cable is sleeved and heat shrunk on to the connector.

The sense pin is used to relay the rotation speed of the fan and the control pin is an open-drain or open-collector output, which requires a . They use variable voltage speed control.

For custom cooling, usually the pump is contrlled by the motherboard cpu fan header ( pin ) and the radiator fans are controlled either by the .

SLEEVING: This cable is not only functional, but also visually very appealing. The Umspannende Net What The actual cable woun is extremely resistant and has just the effect the professional . Of course this will just push . Black shielded female fan connector. These connectors save your wiring from shorting out when disconnected. No more exposed pins with these - pin female shielded connectors. FREE DELIVERY possible on eligible purchases.

This further expands the lifespan of the cable. Sleeving: This cable is not only practical . Wire Pulse Width Modulation ( PWM ) Controlled Fans. The following requirements are measured at the PWM (control) pin of the fan cable connector : PWM Frequency: Target frequency kHz, acceptable operational range kHz to kHz.

Maximum voltage for logic low: VIL = 0. This Y cable connects to your motherboard and controls two PWM fans for optimal performance in noise and cooling. One of the two fan connectors carries the speed control signal. Supports most high-quality PWM fans. Connector A: Female 4Pin Socket. X ATX PC Computer Motherboard Power Cable Switch.

Basically If speed control is mentioned for pin that particular fan header is voltage controlled. You can go around the web to see responces on similar . Your motherboard has five - pin fan connectors. Two of them are for the CPU and three are for the case fans.

Since your case fans are only 3-pin, you will not have the ability to control the case fan speeds , the fans will . The issue is not 3- versus - pin. It is MATCHING the fan design to the mobo header design. Warnings PrimoChill is not responsible . The cable is approximately 50cm long.
