Fan splitter and low noise adopters.

[ChaseDown]

Hello, a motherboard ive been looking at only has 4 fan headers, including the cpu header. But I wanted to run 4 fans plus an aio with 2 additional fans.

So I was going to run 3 fan splitters and 4 of the fans would also have low noise adapters. Will this affect the signal to the fans or hurt my fans in anyway?

No, it won't affect the signal.

 

How fan splitters work is that one fan is able to get the full 4-pin PWM to monitor and maintain speed, while the other fan on the second end of the fan splitter mirrors the signal from the first fan, effectively allowing them to run at the same speed. No extra voltage or power is used this way.

Just don't have LNA between splitter and mobo. That may effect on starting rpm. Have each LNA between splitter and fan.

This is violates the laws of physics. No extra voltage is correct, but it definitely uses more power to drive an extra fan.

I was never really good in physics, sorry.  At least it's an understandable way to interpret splitters, right?

A splitter is creating a parallel circuit. Meaning it will supply the same voltage to all it's branches, which is the same voltage as the headder itself. Each fan will pull the same current it would have if plugged into the header.  Total current is the sum of all the fans currents. Same works for total power. When using spliters just make sure the combined fans don't use more current than the headder can supply or it or something else on the MB will burn out.

Is there a way to check for that? I was gonna use 4 deepcool cf120 rbg fans and 2 deepcool cf140mm rgb fans. Wasn't gonna do rgb but the case best for it!

Most fans say on the hub how much amps or watts they use. And you can check your MB specification for the limit of the header.

The fans use 0.11A and most fan header support at least 1A. You should be able to run them from a header without issue.
