is it safe to use splitter for case fans in one single header?

You can do 4, or more depending on the total amps being pulled from the header.  TYPICALLY (each mobo can be different) fan headers are rated at .8-1.2 amps.  So 1.0 amps is safe to assume imho.

 

Most fans in PC cases (almost = but its easier to google to be sure) take up to .25 amps.

I ran two Corsair (non led) 120MM with a splitter off one header no problem.

Beyond that, you might consider a powered fan splitter. It will have either molex or sata power and only use a fan header for the speeds.


Thanks!

it is mentioned on fan 0.37

Doesn't really matter. You won't hit safety current and even with two fans running at safety current, you are still well within spec for the MB connector. Go ahead and use a splitter.

i have this one . can i use it? well i cant control the speed from that fan hub.

No, just go with the splitter for now.Should be more than sufficient. If you decide to add more fan then use the hub.

yes i have connected two fans by a sleeved cable splitter in one header i.e in Chassis fan header.

 

it runs fine , i can control speed in both fans.

I have four 120mm fans (3 with led and 1 rgb) out of a single connector with a splitter on a H310 board, no problemo.

you mean to say that you have connected all four fans using splitter on a single header of your motherboard?
