I need to get some fans up on my 20H tank since I added my MH pendant. My temperatures as of late are hitting around 83 and I'm a little concerned about it. The issue I'm running into is that since I have an open top, I don't know how/where I'd mount fans. I saw this:

As you can see, it's ridiculously overpriced for a few PC fans and an ac adapter. I'm wondering if anyone has any suggestions to make something similar to that that can be clipped onto the upper rim of the tank.
