system fan connector MSI - B450I GAMING PLUS AC

[NotAVAP]

Hey guys,

 

Before anything I'd like to inform you of my absolute lack of knowledge in these kinds of things (I've never build a PC before) so please be mindful and correct me if I say anything stupid.

 

I'm building a mini ITX setup in the NZXT's H200 case and I wanted to have 4 case fans (two static pressure fans if I decided to use an AIO liquid cooler).

 

My problem is that the motherboard I'm going to be using only has one system fan connector... I couldn't find anywhere what amperage it provides (I suppose it's the basic 1A)

 

Another problem is that I don't know if the connector "supports" PWM.

 

Is it worth it to get a 4 pwm fan splitter (if one even exists?)

 

The motherboard I'll most likely be using is

The fans I'll be using are the

Thank you for helping me guys.

Go mATX instead if you want a compact smaller build, you'll still have all the features you need and actual room to work with, I don't see the appeal of mini-ITX unless you'll be moving the desktop as often as a laptop.

 

Specially being your first build ever it should prove a lot less hasseful for the same experience.

I am going to be moving my desktop every week, so mini ITX is the way to go for me

I'm in the same boat as you OP. I've already built my system but I'm trying to buy a new set of fans to replace my stock fans. I can't find any specific information on MSI's site, not the boards manual I received. If anyone has actually tried connecting fans for this please post! This board is still relevant.

Most motherboards I've looked at recently are 2 amp fan headers and I found one site that confirms for the board you list but I don't know the legitimacy of said site.  That said, the fan you list is .2 amp each so even if it is a 1 amp header, you'd be tight but still under the limit with 4 fans.

 

MSI's site does confirm that the headers are PWM or DC controlled.

 

Two and three way PWM splitters do exist, newegg or amazon have them.  I did a quick search for a 4 way but it looks like most have an extra plug for additional molex power? I used two 3 way splitters when I was using an ITX board myself as there was only one cpu fan header and one system fan header (had 6 fans total).  3 fans on the cpu header, 3 on the system header.

 

They have all 4 wires going to one fan and then three wires going to the rest.  The fourth wire is the speed sensor so the rest just run at whatever that one fan is running at.

 

Here's a crude representation of how I set my fans up;

So i can use a 2 way pcw y cable for the rear fan and cpu?  Board is msi b450itx gamingplus. Case is nzxt h200.

 

Can i connect the case fan and cpu fan into one splitter?
