Hi,I have a Logisys 6 channel fan controller that I want to install to control 3 cooling fans. The fans are rated at 0.950A and I want to be able to run them while the amplifiers are on, and while they are off if need be. Does anyone know if there is a site that shows the proper way to wire them? Any info would be a great help. Thank you.

Is this a car audio product? Did it come with an owner's manual?

So it's a part for a computer? If it operates off of 12 volt DC you might be able to make it work in a vehicle if you know the power requirements and the pin-out. But it would definitely be a custom rig job, and not something you should take on if you don't know what you're doing.

The fans should handle car voltages.

And you just need to power them from the amplifier's ON switch.
There is no point continuing the cooling once the amp is turned off. (The heatsinks may get hotter, but the bits being cooled (ie, semiconductor junctions) are definitely cooling.)
