Loud Biocube fans - quick fix

[edikpok]

The two fans in my Biocube have been driving us crazy over the past month with how loud they were. Most places online suggest getting a new 6x6 fan, but I didn't get around to it...

So today I decided to lubricate the bearings. Removed my DIY splashguard, removed the aluminum piece that covers the fans, unscrewed the fans, removed the sticker and applied a drop of lubrication oil (not wd40). Worked it in by manually turning fans, and re-assembled the whole thing. Worked VERY well! Wife is very happy with how quite the fans are. Highly recommend to all of you who have this problem - it only takes 10 minutes...
