It varies from 1 to 3 ... but I do have my rad fans on the controller (3 fans soldered into one lead). It's still controlling, but looks like I blew out the LED ??? Dunno, got another on order though.[/QUOTE]


My controller works well with two fans per channel.
Having three fans per channel, the led rpm flashes from 1500 RPM's( speed of my fans)
to 0 RPM's every 2 seconds, but keeps the fans at set speeds.

these controllers may not be able to handle more that two fans per channel, tho its rated for 1A per channel and my fans are 0.24A per fan.

Well see how long it lasts.

If you get another one and it does the same thing or not with three fans on one channel, let me know. If not i will RMA this one.
