PWM spliter 100% all the time

[kudi92]

Hello \o

 

I just upgradet my case from antec 900(version 1) to fractal R5 and put 2 of noctuas 3000rpm industrials to the fron(got them 5th of the price and unsused).

 

I split the case fan port(number 3) with akasa flexa fp3s. alone the port will operate normaly, but when the splitter is added al lthe fans will spin at 100%

 

Is there something im doing wrong or is there some more little thing i need to get to make  the front fans work and operate.

 

sry for the bad english and <3

 

mobo: m5a99x evo r2.0

splitter: flexa fp3s

cpu cooling: cooler master seidon 120v

fans: 3*3000 industrials, stock R5 fans and stock seidon fan

Do you have SATA power plugged in? That does it.

 

EDIT: If you do, unplug it.

If i unplug the sata then non of them will spin. the motherboard header on the loom only has a ground and cha fan pwr wires in it.

There's a possibility that even though your motherboard has 4 pin headers, it might still be managing the fans using voltage instead of actual PWM

 

In which case i don't think the akasa splitter would work, see comments here

Hm. You can try setting the fans to PWM mode in the BIOS. They're probably default to DC.

thanks for the tips, i will check them soon... in the offhand, what splitters would there be that would work for voltage controld headers?

I use one of the cheapo Y cables for PWM fans that came with my Fractal fans. it shouldn't matter if they're "meant" for DC or PWM if it's just a splitter. At least for me, I can use either.
