Fan Noise

Idon't know how these fans look, But I had a computer fan that started to make noise.
I peeled the decal off of one side, and put a drop of thin machine oil onto the bearing.
It would stay quiet for about 2 months and then I would have to repeat.
Any thin oil would work. All depends on the condition of the bearing. It does not take much oil!

Many fans have sealed bearings, so I wouldn't recommend oil, as it may not work well, but also hat oil could get into your tank. Fans are cheap, so I would just replace

I agree...oil is just too risky.

You certainly do not want oil to fall into the water. That is why I said just a little. You could always put oil onto a toothpick and apply it like that.
But you are right, these computer like fans are cheap. And that is why you won't find any with sealed bearings

All the fans I have ever purchased are sealed, and over the years I have bought many as I own a web hosting company and have a half decent sized data centre so keeping fans on stock is always necessary... Go to Memory Express, get a Sunon fan, they are the best and will cost you about $10-15 for the one that fits the canopy.

I'm good with the computer fan idea but correct me if i'm wrong. I have to convert 120 Volt AC to 12 Volt DC. There's no room in the unit to accomodate any kind of transformer to step down the voltage. The issue is there are three power cords coming into the light. One for the MH bulb, one for the Actinic and one for the lunar lights.
There's really no room to put in anything else.

My fan is the right connection for the unit (12V), basically the little rectangle plug that is stock with computer fans. My fan that came stock in it is a Sunon. I doubt yours is running at 120V, but yeah you need to verify this.
