I took my 6x24 watt fixture down for a few months and decided to give a shot again.
I plugged it in and first thing I noticed was the fans were not working.
I figured the weak link these was the power supply and replaced it, but no fans.
So I pulled it apart and first thing I noticed was the 2 red wires.
I'm assuming they are suppose to be connected together.

Anyone have a picture of a new ATI fan?

I guess the problem is both red wires were attached on the fan body, but have broken off.

So I measured these fans and they are 2-1/2" square.
Everywhere I look, the only ATI replacement fans I can find are either 3" or 3-1/2".

I wonder if ATI calls the small fans 3"?

Thanks.
I heard back from ATI through their web contact form.
I ordered new fans.
I even found a you tube video that shows how to remove the fans with out taking the whole case apart.

I would just strip the red wires and shove them back into the connectors. All that looks wrong to me. Of course replacing the fans is rather cheap too.

EDIT:
NVM I looked again and it looks as though they broke off the fan itself. In that case only thing to do is to replace them. ATI uses a weird size, so it's best to just replace them. The last time I replaced mine I go them from premium aquatics. 14.99$ a piece if memory serves me correct.

Yeah, I looked using a flashlight and a magnifying glass and couldn't see any connector, that's why I thought that maybe the red wires had been connected at one time.
I found the fans a little cheaper on the ATI online parts store.
If I would have atleast done a google search first ( instead of tearing into the case) I would have found all the info out there on the subject.

Inside the fan is a circuit board.. The wires were soldered there at one time.

+1

it can be re-soldered back on. it should be very close to where the black wire is soldered. peel up the paper covering the motor.

I see corrosion.. I would replace the fans (which the are doing anyways) vs repairing whats there..
