It should be pulling air through the Amiga and out the fan. This can !have the disadvantage of also pulling dust into your Amiga, but it's done this !way because the fan is mounted in the power supply. If it forced air in from !the back, it would get heated across the supply before going to your boards !and all. Okay, since we are on the subject, what about that dust? I notice I get quite a buildup (lint and pollen in the spring). Any problems with this? It's about 2cm thick now, and pushing my A2620 card out. My upright vacuum cleaner broke off one of its brushes when I rolled it over the PC slots. Seriously though, I spray it reasonably clean every now and then. Should the board be meticulously cleaned? Also, I have my cover off frequently and for long periods of time (week, here or there) to play with my hard drives. Then the beast no longer has the nice, well-engineered laminar air flow. Anyone had any heatup problems as a result of this?

I've had my systems real dusty (especially the one at home, my cats used to sleep next to it in wintertime to keep warm) without any obvious problems. I suppose it could goober up the contacts on the unused slots if it go too excessive, and it'll definitely cause problems if any gets in the floppy drives. > Also, I have my cover off frequently and for long periods of time (week, here > or there) to play with my hard drives.

Many of the machines around work have no covers and lots of extra cards and such in them (the one I'm typing on has a card using or obscuring every slot except the video slot), and far as I know we've never had any heat problems. It could happen, though, especially if you're in a hot, humid, unairconditioned room like many folks this time of year. -- Dave Haynie Commodore-Amiga (Systems Engineering) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: D-DAVE H BIX: hazy Be careful what you wish for -- you just might get it
