I have a fan that needs replacing on my aqualight. Any advice? The power supply for the fan comes directly from the light (white cable). I would like to get a replacement that is the same (I see some for sale that have power cables). I am guessing that if I pry the fan open (it has screws that have been cut off so it can no longer be opened), I will be able to unattach the power cable and use it for a new fan. The new fan will have to have screws so that it could be opened and then the power cable could be attached.

Where does someone buy a fan like this? Also, would a new fan be openable, so that I could attach the power source?

Thanks.

Do you have a DVOM? (Digital Volt Ohm Meter) If so, check the voltage coming off of that white wire. (very carefully.. we don't want any electrocuted people here :p:) If its 12v DC then you should be fine going with a computer fan. If its AC or a different voltage, you may be in a bit of a pickle. If AC, you'd need to find an AC fan to replace it, though I seriously doubt they'd use an AC motor in that fan. If its lower than 12v, you could still use a pc fan, it will just turn slower than it is rated to, and therefore move less air than rated for. If more than 12v, which I also doubt, you may damage a pc fan or have it burn out relatively quickly, and you may notice that it will be louder than rated for, since the fan will be in overdrive.

Is there any way to contact the manufacturer and order a replacement fan from them? If so, that'd be what I'd do. If not, check that voltage, and see if you can find an adequate replacement from Fry's Electronics, or something of the such. Good luck to you. :)

Oh, final thought: you shouldn't need to break open the new fan. Splice the wire you have coming out of the fixture for the current fan, and attach those wires to the wires coming out of the new fan. If its ~12v, the wiring on the new fan will be fine to handle that... either solder the connections and wrap with electrical tape or use those twist-on connectors and tape those on. :)

Thanks for the info, I will try to contact the manufacturer.

I looked at ebay, and it does look like a computer fan. What about the connection? If I pry open my fan, it may just have wiring and no connector on it. By connector, I mean what these fans have:

The fans you're looking at buying are 120mm fans, or 4 3/4" wide. Those will be much larger than the stock fan on that fixture... if I'm not mistaken, they use something like a 40mm fan. Got a ruler handy? Measure the width of the fan for us and please post it?
 
I just measured the fan. It is 3 1/8 inches by 3 1/8 inched by 1 1/2 inches deep. This is a pretty big light, it is 72 inches long.
