Do I need a fan header?

[Succumb]

Hello! I am here to ask if i need any extra fan headers/splitters for my build, since I am planning to install 4-5 fans. 3 in the front and 1-2 in the back. Here's my build

@SuccumbEach fan connector supports 1A and 12V of fan power and you have 3, one for cpu and two for case. You can use a Y/splitter cable as long you do not go over the power limit.

I'd even suggest Arctic Freezer PST type fans as well. You can connect the fans to each other, thus even run 4-5 fans from a single fan header.

 

I would get another mobo though. This bare, naked VRM does send chills down my spine. And this board would look "funny" built in, Esp in a case as huge as that CM.

I'd probably suggest only running non-RGB fans off the MB.

 

The CPU fan is PWM, you can get a PWM controller, plug the CPU fan into that, and then plug half a dozen PWM fans into the controller so that the fan speeds move with the CPU cooling requirements. You can alternatively connect it to the 4-pin "chassis fan 1" and set the BIOS to use use PWM instead of DC. PWM controllers connect to a separate SATA/Molex power connector so that the power isn't being pulled from the MB.

 

The fan controller is what you should do instead of splitters on the motherboard to prevent drawing too much current from the MB. It should be fine, but some fans that include LED's draw more power than expected.

 

This is one option and includes RGB controllers

This is another option, stand-alone PWM/DC fan controller

Alright, very interesting indeed. Thanks for the answer! :D, now I wanna let you know that I won't be buying the rgb version of RF 120, instead I will be buying the single color version, RF 120 R, would there be a difference when it comes to power draw? 

 

also how much more fans can I put in here if I am not willing to buy any fan controller/splitter

I doubt a single-color LED will draw any less power than the RGB models, the RGB models just have an additional chip on them to program the color. The all-one-color models lack that chip, and sometimes there's a switch to turn the LED's off.

 

Mostly the point is that a non-LED fan pulls about 2 watts, but a LED fan may pull up to 8 watts. You have to do this calculation yourself though.

 

Deepcool RF RGB's are 2.76W each. T

The Red-only (RF) model is 1.92 W each.

The TF120 S, which has no LED's use 1.8 W. So there's an entire 1 watt difference. The RED-only model is just barely more power than a non-LED model.

 

Some of the cheaper-looking fans are also 2.4watts.

 

My point earlier is to avoid putting splitters on the motherboard fan power connectors since the connectors are intended to only have one fan on it. You may get away with pulling more power from it if the fans themselves provided the motherboard was designed to allow it. The maximum is likely 1A (12watts) So assuming that  you use the RF Red's, you can have 6, at most.
