Scanner Fans: AC or DC?

[Stuka]

I essentially agree with everything you said but you don't necessarily need two fans. As long as you have one fan and a hole (or holes) you will be OK. This is basically how computer cases work that have no fans other than the power supply fan.

8 fans in my PC case, counting the power supply.....

Of course, my machine wasn't really built with just running MS Office in mind, and I MIGHT be practicing just a little bit of overkill in the cooling...

Concerning filters -

Any recommendations on some sort of filter mount to replace the wire fanguard for 80mm fans?

I'm not going to use a filter. I am going to seal my optics with a pexiglass enclosure. I can blow out the case with a can of air if it gets too dusty.
