350 mA-2000 mA ( 24 W max. ) or a total of 1 A-7A (84 W max.) at 12V.
I have 8 mobo fan headers(all PWM) (including PSU & CPU fan header ). The Mobo is a 24 pin main and 8 pin ATX.
Given the stated support specs, I added all current fan Amps together, and I'm still unsure if the Mobo is able to carry the load.
Here is a list of installed fans;
Amp. input W. (all fans 12V)
Front 120mm - .30 1.8 PWM (4pin)
Back 120 " - .35 4.2 (3pin) will run 100% for now. Have 2spd controller.
side 80 " - .15 1.8 PWM
side 80 " - .15 1.8
side 80 " - .25 ? (not found)
CPU hs 92 " - .25 ? ( " )
I'm a new builder, and don't have alot of knowledge of computations related to this total draw.
My simple math results, related to Amps = 1.36 approx. This seems to fall below 7 A max. IDK. AMPs(1.36)X Volts(12.)= 16.32 Watts ? is this correct?
I found input W for only 4 fans so I'm unsure of total.
Will this fan load be within spec, for all fans to be connected on board?
Could you link me to a good tech artical or tutorial related to the subject?
