4 pin fan splitter?

[boey]

Hi, I bought a ML240L RGB from Cooler Master but I realise my micro itx motherboard only has 2 4 pin connectors, whereas the AIO needs a 3 pin for the pump and 4 pin for the fans.

 

Would it be okay if i bought a 4 pin fan splitter(it splits into 4) and plugged it into one of the fan headers?

 

I don't know if it will sufficiently power the fans/pump enough or not, but there is one 3 pin connector(that's connected to the one of said 4 pin headers) that is connected to a SATA cable(i assume it's powering the 2 sata drives connected to this cable, since no other cable is attached to said sata cable), an AIO pump and 2 fans.

 

If I were to plug a 4 pin fan splitter into a 4 pin header on the motherboard, and attach 2 4 pin cables(from aio fans) onto the splitter, then attach the 3 pin pump header onto the other 4 pin header on the motherboard would it work? Thanks.

What motherboard are you using?

You can plug 3-pin fan things into 4 pin PWM headers - the connected device will just run at full speed unless it can be adjusted down in the BIOS or with motherboard fan control software.

For AIO pumps, a motherboard fan header should be fine for power, but I would not split it into pump + another fan.

Depending on the fans, you could run several off of the other fan header (I have a passive 3 way PWM splitter).

Yeah ok thanks, I used 2 fans on a splitter that connected to the chassis fan header and the pump on a seperate cpu fan header and it’s working fine. I realise my H61 board is too old for RGB headers so I need to spend more money on a cooler master fan hub to power the rgb by sata
