Need an fan controller that will hold up 120W, 12V.

post #1 of 5
Thread Starter 
Hi, i need a fan controller that will hold up around 30 fans - all the fans are 120W, 12V.
12V
10A (all of the fans)
so a fan controller that can hold up to 10A.

Lamptron so some really high wattage controllers but they are around 30W per channel so you will have to split up some of you fans on to each channel.

What are you cooling with 30 fans, is it water cooling rads by any chance?

If so how many rads and what are you cooling?

they are not for computers.. something else.
but if i connect all the fans in parallel than the current is dividing..
so ill need 360W.
I Have 30fans.
they all need 10A
but because i connect in parallel, ill need more watts of power because the currnet is dividing. so 360w is 1A per fan and that overkill but im going to add more fans and such..
so a fan controller around 300W-290W is good.
edit :
i found this
http://www.ebay.com/itm/12V-30A-300W-DC-Motor-Speed-Control-PWM-HHO-RC-Controller-Max-300W-/110892022307
this is PWM controller, but not all my fans have 4 wires, most of them just + and -.
will this work for them?

well in that case there is no consumer fan controller that can handle that, try the 5v molex trick to make them run slower.

Sorry but this is past my knowledge, I am used to working with 03A or less fans. What mad experiment are you doing?

does PWM Controller will work? my fans are 2 wires. + and -.
no experiment, just some project for myself for fun.
fans are awesome, dont they?
