I doubt if anyone was considering using the dinky little CPU fan.
A heatsink in my hand from an ancient 800 MHz Celeron is 3 x 2.5 x 1" with
25 fins. Using a 4.5" standard size muffin fan blowing transverse thru the
fins it will move a lot of heat. I'll leave it to those with more time on
their hands to compute all the variables.
Ive been up since 05:30 and off to bed.
