For what it's worth...don't know if it belongs but anyway...

I've been working quite long hours at the computer (two screens) and have found that the heat coming of the screens was drying me out and affecting me.

I've just fitted up on my desk a spare case fan I have so it blows along the screen and takes the heat away. Seems to be helping.

Anyone else affected like this?

also probably depends on the ambient temp as well....

for good 'ergonomics' you should be an arms lenght away from your screens, and the room well ventilated.

that said, with todays 32deg temp it was pretty much running the air-con full blast - something i really hate to do in the first place (air-con that is).
