Do I Need A Fan Controller?

Hey guys.

So I added a fan controller to my build because I thought I needed one but I may not. I have no idea which is why I'm asking. So I bought 5 case fans because I'm not going to be using the stock ones that come with the case. I plan on having 1 rear exhaust fan, 2 fans at the top of the case and 2 and they very front. I would need 5 ports to plug all the fans into my motherboard but I don't think there is any motherboard that has 5 fan ports which is why I added the fan controller.

Is this necessary? To use all 5 fans will I have to get a fan controller?

Thanks for you're help in advance.

According to the specs the mobo has 3 4-pin fan connectors and 1 for the cpu fan. You can control fans connected to these with the bios. To use control two more fans you'd need either a fan splitter or a controller. You can also power them with a molex connector though they can't be controlled.

This next part is important. Those fans use 3 pin connectors while the mobo uses 4 pin. They are compatible but you will be unable to control the speed. You'd need the 4 pin fans for that which are called PWM fans. In other words unless you get pwm fans you would need a compatible controller for 5 3 pin fans. If you get 4 pin ones you can buy 1 or two fan splitters to control all the fans.

Thank you for the help. I already purchased 5 of the case fans mentioned so i have to stick with them now.

Would the fan controller I selected solve my problem? (https://ca.pcpartpicker.com/part/nzxt-fan-controller-sentry2)

Is doesn't support 4-pin fans but I guess that shouldn't be a problem considering the fans, as you mentioned, are 3-pin connectors.

I have the external Nzxt fan controller on a spare pc. I think yours is similar except you slot it in the hard drive bay. Comes with 5 fan controller feeds, and 5 fan temp leads. You can set it you manual or auto. For example, if you expect a heavy gaming session you can crank up the fan speed for the expected increase in temps. OR...it it to "auto" and as the temps raise, your fan speed increases.
