Do fan splitters work with PWM?

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.

Can I connect PWM fans together?

Connect two PWM fans to your mainboard’s CPU socket. Use multiple Y cables to connect a series of up to five PWM fans and provide as much extra cooling as desired. Power drawn into your CPU cooler is adjusted depending on its temperature.

Are PWM case fans worth it?

In many cases, PWM versions of fans cost only a few dollars more. For some, this alone can make builds loud when they should be silent. Non-PWM fans, at worst, will run at max speed if the motherboard doesn’t have voltage control settings.

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 use 2 fan splitters?

You don’t need to go Molex – you have enough mobo fan ports to add 4 fans if you use splitters. And Mattios is wrong – connecting 2 fans to one mobo fan port using a splitter does not change the fan speeds. Most mobo fan ports can supply enough current to support two fans, but more than 2 on one port is risky.

How many PWM fans can you have?

The female end of the Fan Hub connects to the motherboard which then branches into several male headers for you to connect Fans to. A Fan Hub can typically connect upto 10 fans both 3 and 4 pin PWM or DC fans.

How many fan splitters can I use?

So there’s a “rule of thumb”: you can connect up to TWO fans (normal ones) to any mobo fan header, but NOT MORE. That is why a Y-splitter with only two outputs can work. Although you can buy splitters with more than two output connectors, DO NOT use them!

Does using a fan splitter reduce speed?

No, they will all run the same speed.

Are PWM fans 3 or 4-pin?

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.

What is a PWM 2-fan splitter cable?

Register today The Cable Matters PWM 2-Fan Splitter Cable provides a quick and inexpensive solution for controlling two case fans in a computer case. Eliminate the need for a separate fan control by using the fan port on a motherboard.

Will this fan splitter allow me to adjust RPMs for both fans?

This splitter will still allow you to adjust RPMs for both fans, just not individually. They’ll both run at the same speed. This is normal and expected when using a PWM fan splitter.

How many case fans can I control with this fan splitter?

I was able to control 2 case fans using this splitter. Only 1 fan has feedback, as two feedbacks would cause issues with the fan controller built in to your motherboard. Both like fans will run the same speed, only the feedback fan will be monitored for failure.

How do you use a fan port on a motherboard?

Eliminate the need for a separate fan control by using the fan port on a motherboard. Fan speed regulation with the 4th RPM sensing pin connected to the main fan and the 3pin plug connected to the 2nd (slave) fan. Maximize the use of a single motherboard fan port with this convenient 1 to 2 splitter cable.
