Stupid fan wiring...

12 volt 3 amp with alligator clips! That would work great. Just because you only need 1400 mA, doesn't mean a 3 amp power supply can't be used. It will only supply what the fan draws, no more. Better to have a larger supply working at 15-20% than a smaller one at 90%.

Just as an FYI, I'm pretty sure the yellow wire is strictly RPM/monitoring, doesn't actually control anything. I remember having red/black molex fans with fan control.

Oh really? I didn't realize it would only draw what it needed. I got one from B&E that is 1500 mA.

I am going to have to experiment because the wires are not colored, they have clear coating on all of them.

One of these days I'll have enough time to get back to this project as well as actually getting the tank running!
