Hey guys, I'll admit I haven't read all 40 pages of this thread so far... but I've read most. So, I apologize in advance if something like this has already been posted and I missed it.
Anyway, I have a couple of pics of a 40mm fan that I've added to the Circu-Pipe. It's simple, clean, and out of the way. I just thought I'd share it with you all in case you needed to drop a quick couple of degrees.
