Hey guys !

I want to ask a suggestion .

I have 5 120mm fans . 4 fans are Cooler master masterfan 120 ML (blue Led) (0.37 amp of safety current from each) http://www.coolermaster.com/cooling/case-fan/masterfan-mf120l-blue/

and one is corsair case stock casing fan of 120mm (0.38amp) white led.

all these 5 fans come up with 3 pin connector and my psu TX650M got 4 female molex peripheral connectors .

Now should i buy 3 molex 4 pin to 3 pin male connector or should i buy 2 Y splitter?

I know by connecting to psu i cant control the speed but in mobo i can.

My motherboard is ASUS Z370-H gaming having ,

1 Cpu Fan header , 1 Cpu Opt fan header , 2 Chasis Fan headers , 1 AIO pump header.

I am using CPU cooler air fan in CPU .



Your help will be appreciated.

The least amperage each header provides should be 1 A. But better check it though your manual. Therefore you should be safe using a single header for 2 fans with a total of 0.37x2= 0.74 A.

ok but my mobo manual says that "Cpu_fan connector supports the cpu fan of maximum 1A (12v) fan power"
now thats for cpu but not have mentioned for the rest of chassis fan headers and AIO pump header.
Thats confusing ..
