Horizontal vs vertical fins...
Hmmm.... that makes sense considering heat rises. Another great
observation based on facts hiding in plain view. Of course he WOULD
mention it AFTER you had completed your project ! Murphy strikes again.
Thanks.

Nicely done.

Here is my solution - using very quiet computer fans. See the link at the bottom of the

I sometimes use a small resistor to slow them down, but they run on 12v and
usually spec out around 15-19 dB noise factor.
I just could not spend over $40 on the TT fan, when I could make one for less
than $10 - including buying a brand new fan. Mine are CoolerMaster fans that
cost me $7 I think.
Maybe my plan will spur some other ideas.
