No idea what the big deal is about.... ;)
I just fire up the PDP-11/73 (RL02, RX02, RD52x3,), then
Microvax-II/GPX, Then the PDP-8f....
WHAT? OH YES IT'S LOUD!
The 11.73 has fans in the RX02, BA11 box, Rack back door near top and

The PDP8f has two very high volume fans.
The only thing I have that's close to that is the homebrew S100 case

Warms the room well and makes the power meter spin pretty good too.
