Do i need a 4 pin splitter?

[daanwp28]

Hello,

Im about to buy 7 fans on AliExpress to replace my earraping 4 fans. So in total i have 8 fans including my cpu fan. Im buying fans that give a red led ring. But i haven't come to a solution of how many splitter i have to buy and do i actually have to buy a splitter. The other 3 fans will be attached to the top of my case. It are 120 mm fans though. The fans have a 3 pin connecter and a molex. Ive heard that molex just sucks in some ways so i want it in my motherboard.

These are my Asrock z270 k4 motherboard fan and voltage specs
- 1 x CPU Fan Connector (4-pin) 1A
- 2 x Chassis Fan Connectors (4-pin) (Smart Fan Speed Control) 1.5A
- 1 x Chassis Optional/Water Pump Fan Connector (4-pin) (Smart Fan Speed Control)

Something i also have read, is that my 4 pin connecters on the motherboard can only handle 1A. It isn't listened how many 'A' the fans are, but most of them are something like 0.30A. So you can't put 4 fans in a one splitter, otherwise it was a risk you could damage your motherboard.

Do i need to buy a splitter of how many or like a y splitter on two 4 pins to prevent my motherboard is getting damaged?

Any help would be appreciated!

Whether it's an amp or an amp and a half....you can't go over it.

You need to find out what each fan draws and the total draw on each header can't exceed whatever it is.

You can get splitters to split into two or three or even four I think.

You should probably use a powered fan hub instead of that many passive splitter cables. A powered hub uses the power from an unused drive cable instead of taking power from the motherboard header. There are even some that use a motherboard header to control speed of the fans. These aren't too expensive either.
