Case fan connectors

[ChichoDB]

My case have 2 fans, one at the front and one at the bottom. And they both have a molex connector and a 4 pin. Should I connect both of the connectors or with 1 of them I am fine? Right now I have connected the back fan to Mobo (which only has one fan connector) and the other one only to molex (which is very noisy).

Thanks

You only need to plug in one of the two connectors.

Connecting to molex simply means it will run at full speed all the time thus the noise.

If you only have 1 connector then get a splitter or a fan hub?

If that's not an option, I would go for 1 intake at the front to maintain that positive pressure.

Would this work?

If you have only 1 fan you should ALWAYS put it top rear as exhaust.

I would recommend buying a fan splitter and running them both off the motherboard.

You have the CPF02 in that link, get the CPF01 instead. the CPF02 will split 1 into 3, seeing as you have only 2 fans, you only need 2 connections. But yes, it will work.

 

Get the CPF01

What fans do you have?
