I would post a eBay link where I got my fans from but I think that is against the forum rules these days; however, if you search:
NEW Ultimate Oceanic Biocube 8 & 14 dual Fan upgrade Kit Plug Play BALL BEARINGS
in eBay you should find that I bought for under $30.
The fans are quite loud but they do not rattle like the stock ones did. I would take a picture of the wiring but all my wiring is modded and would probably do you no good. No worries though because the fans are super easy to install. All you have to do is plug and play.
Wanted to say thanks. Super easy to Install and I even cut off the vents like you posted. I have super air flow now and tank temp is at 78 with no ice,it's never that low in the summer.I'm usually at 82. It is louder but their is no rattling and its worth it.
I paid 25 shipping included.
