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!

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
