2 fans but 1 system fan header

Mikkel_1989 · Mar 27, 2016

Hi! I'm planning on buying a corsair SPEC-02 case which comes with 2 case fans, 1 front intake and 1 rear exhaust. My motherboard that i have bought (ASUS H110M-A) only have 1 system fan header. I have two questions:

1) What are my options if I want to connect both fans?

2) Will 1 fan be enough?

Very much thanks in advance!

You can split the header-

from my motherboard manual I read that the system fan header can take 1 A (12 W).. will two fans go above this ? one of the fans has LED lights

Rock on you crazy diamond!
@ Mikkel_1989: Yes, you can use a splitter, the only possible issue is that both fans will synchronise at the same speed, it's unlikely two fans will draw one amp, even at full speed.

The 120mm LED fan operates at 0.4 amps. The rear 120mm without LED would be less, 0.1-0.2 amps. Should be fine.

@ coozie7 - I was there for 'The Wall' performance in 1980 at the forum, Los Angeles.

okay, so my motherboard system fan header is 4-pin and the fans in the SPEC-02 case is 3-pin.. does that work, and what consequences will it have?

Mikkel_1989 :

They are not controlled by pwm. Plug them in they will work fine.
