Is it safe to plug fan splitters into other fan splitters? I was planning to use an ITX motherboard for my build, and those dont have many fan headers most of the time, so I was going to buy 2x 4 fan PWN splitter and plug those into each other. The splitters I am going to be buying have MOLEX 4 pin connectors to provide more power. http://www.frozencpu.com/products/14982/cab-627/EK_4-Pin_PWM_4-Way_Splitter_Cable_-_Sleeved_Black_Black.html?id=KppXD7AX&mv_pc=18547

 

One end plugs into the 4 pin motherboard connector, and one end plugs into a molex connector. 

I like the color scheme of Noctua fans. Deal with it. Forget about the bad memories of the past.

i do this :D ya its fine. one thing i noticed is my super cheap case fan (the included with the case one) needed some power. it was on the last end of the daisy chain and wouldnt spin so i hooked it to the mobo.

Do you think this is because of the daisy chaining or because it does not support PWM?

There are PCB fan splitters with 4pin connectors, and you plug in 2 molex connectors to the PCB to power it. Can you control those PWM fans? http://www.frozencpu.com/products/7614/bus-141/Bitspower_X-Station_Power_Extension_II_-_UV_LED_BP-XSP2M-UV.html?tl=c17s424b145&id=KppXD7AX&mv_pc=19012

definitely daisychain. ive had it hooked to a splitter before but the dasiychain killed the power draw. i pump as little power into my fans as possible. remember, the more cables you have the less effective a connection becomes.

I understand resistivity but, you must have been running your fans pretty low to not be able to start the fan up.

 

@WunderWaffle the PCB you linked to runs 12 3 pin headers (No PWM) but at 3 different voltages: 4 at 12v, 4 at 7v and 4 at 5v

It also has 8 4 pin ports.

 

EDIT: OOOOOOh. it has 8 MOLEX connectors... Woops...

Do you know the pin-out of 4 pins?

 

12v ground ground 5v

 

With this you could achieve 12,7, or 5 V without any need for a pot/resistor to tweak it.

 

No, that does not support PWM but, yes it does support running fans at multiple speeds.

No need  ;)

 

Honestly, if I were you I would go with the first thing you linked to. Might require some tweaking but it should work...

 

I am not sure about the problems whatthe_fuzz was experiencing. At the length and quality of the wires the splitters should be using the extra daisy chains should add very little resistance.

 

I think the fan he was using was probably low quality and did not behave well to undervolting.

 

Seeing the quality of the other components in your build you probably wont experience this your fans but it is worth looking at reviews to make sure the fans you get do support it.
