answer from livechat=over 15Watt
i don't know what you mean.
1.5 A or even 2 A
1.5 A X 12 V = 18 Watt
that means it is more than 15 Watt.
all headers deliver more than 15 Watt.
if it's 10 or 15 or 18,
it's much enough, to connect 2 fans on one header with a Y cabel.
this would need perhaps 2 or 3 watts.
How many fans are you plaining to use , right now I have 6 120mm . I don't think it would be a good to run anymore . By the way I am also using a Cousair H-70 Radiator for CPU with fans two blowing out the back , works good , Keeps My Xeon at 45 C No mater what I throw at it .
If I had the $$$ Santa would bring me a Cousair 650t so I could put a 240mm radiator in the top . Perfect set up. ( come on Santa )
1 Zalmann CNPS 9700 NT for the CPU
1 Papst 4412 F/2GL, 120mm / 1,25 Watts for FRONT
2 Papst 612 F/2, 60mm / 1,1 Watts for REAR
as the board has only one REAR header, we want to connect our two 60mm fans to this one rear header with a Y cable.
the tacho (yellow) from the Y cable goes to one 60mm fan and the tacho of the second 60mm fan goes to the AUX header.
so both rear fans can be controlled by the REAR fan header, though both RPM are monitored, one as REAR and one as AUX.
