Just a note on larger fans, keep cables & fingers out and do pay
the extra for proper grills - even on the inside if you ever go into
a machine with the fans running. Big fans have a lot of energy,
and whilst a Panaflo H 80mm will cut deep into a finger drawing
blood (and shattering phenolic blades) the bigger fans do worse.
Some SGI colleagues call the Panaflo "Moulineux Food Processors"
in terms of carrot choppers re sharp blades. Bigger 172mm are
always shut-off & unplugged, "don't go there" :-)
