I just did a bit of research on the Web regarding cooling fans for
computers, and the main issue I see with using these is the CFM (cubic feet
per minute) rating. This may be where the advantage of the Icecap Fans is
obvious. I didn't see any 12 VDC computer fans that moved more than 30 CFM.
This may work in a smaller tank setup, but could prove problematic for a
multi Halide or Compact Flourescent setup, which probably generates a lot
more heat than a computer case, just a guess on my part.

So if you consider the larger 4" Icecap cost at $43 (www.marinedepot.com)
and the cost of moving the same amount of air with 3-4 DIY computer fans,
the cost difference becomes almost negligible, doesn't it?

Dave
