What is PWM Y splitter?

What is PWM Y splitter?

Product Description. 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.

Does PWM work with splitter?

If you want your motherboard to control the cooling inside your computer then Gelid’s 1-to-4 PWM Fan Splitter could be what you are looking for. Gelid’s 1-to-4 PWM Fan Splitter allows the user to connect up to four PWM fans from just one PWM fan header on the motherboard.

Do you need 4 pins for PWM?

Pulse Width Modulation You’ll find PWM in controlling devices like servo motors, dimmers, buzzers, or as a telecommunication encoder. So, why does a 4-pin PWM header exist on a motherboard? The reason is quite simple: The 4-pin PWM header is used to control the cooling fan that’s attached to the enclosure.

Where do I connect 4 pin PWM?

If you want to use the PWM function then the 4 Pin fan must be connected to a 4 Pin header on the motherboard. If you connect the 4 Pin fan connector to a 3 Pin header, then the fan will run at maximum RPM. 1.

Where do I connect PWM cable?

The PWM cable goes directly into the Motherboard. Most of the users cannot install PWM cables just because they are putting them in the wrong Header. PWM cable comes with a 4-pin header, where most of the case fans are basically installed on three-pin headers.

Can you split 4-pin fans?

Yes, you can purchase a splitter cable and power two fans from a single motherboard header. I have a CPU cooler that has two PWM fans. I’m using a splitter to power both fans and it works great.

What does 4 pin PWM mean?

Pulse width modulation (PWM)
PWM Fans or 4-Pin Fans 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.

How does a fan Y splitter work?

The Y-splitter in your link is a 4-pin splitter. You plug the female connector (with 4 holes) into a mobo male header (with 4 pins). You then plug two fans’ female connectors into the two male outputs of the splitter.

Do I need to plug in the PWM cable?

PWM stands for “Pulse Width Modulation”, this allows the motherboard bios to control your fan speeds based upon temperature variations. The PWM connector at the end of the fan cable is plugged onto the PWM headers located directly to the motherboard.

Does fan splitter reduce speed?

No, they will all run the same speed.

Can I use a 4-pin splitter for 3 pin fans?

Yes! PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though.

Can you control fans with a splitter?

You won’t be able to control the fan speed using that fan splitter. The power is coming from the PSU via a Molex connector instead of using power from the motherboard. There are 2 pins missing on the motherboard fan connector so the motherboard won’t be able to use PWM neither voltage to control the fan speeds.
