View Full Version : help with cooling system ?

Hi.... I am setting up a few small fans to cool radio and one for the linear,
On the fans it says 12v, 0.25amp , 3.0w ... Will this mean if I just give them 12v
They will die ?
Is it just a relay to protect them ? If so what should I be using ? My power supply is, 9v~16v , 30amp, approx 450w...
Thanks for any help you can give...

The fans are good for 12 volts, the other readings are the amp draw and watts, the fans will be fine on a 12 volt system.

Too easy ! I have a heap of 12~14v, 25amp relays that are fused with blade fuse.
I will use one so I don't burn out the off / on switches..
Thanks for the help...
