This thread begs a question - how much do you think it'd be worth to do things more efficiently?

this is a strict business decision involving sustainability and TCO. if it takes one watt of mechanical to transfer heat away from every watt delivered, whereas ambient air with good-enough filtration will let one watt of roof fan transfer the heat away from five delivered watts, then it's a no-brainer. but as i said at the outset, i am vexed at the moment by the filtration costs. -- Paul Vixie
