Fan Noise

I concur with Sphelps...but you can also get replacement fans from Coralife and it will probably be quiet for a while before it too gets noisy.

If you go with the PC fan option, there are several good fans out there that are really quite quiet. You could also put more than one fan in as I found multiple spots when I opened my fixture. Since you have to re-wire the DC fan in anyway, doing two is just as easy.

I agree, replace the fan...

I have the same unit, and mine is quite, I don't hear a thing. You can go to Memory Express (2 locations in Calgary) and get one there, most likely will be under $10

Your old one, the bearings are probably worn out or faulty.

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.
