The fact that the dans are running at max should tell you something... A quick & dirty solution would be to drill a couple of holes into the door, one near the top, and one near the bottom. Get a couple of 120 mm fans. Put them in holes in the the bottom of the door as an intake fans. Leave the top hole open as an exhaust. Hook the fans up to an old power supply and you're done. Need more cooling? Add more fans. It might be a good idea put some filter material in front of the intake fans, lest you want to breed dust puppies. :-) Roland -- R.F.Smith http://www.xs4all.nl/~rsmith/ [plain text _non-HTML_ PGP/GnuPG encrypted/signed email much appreciated] pgp: 1A2B 477F 9970 BA3C 2914 B7CE 1277 EFB0 C321 A725 (KeyID: C321A725) pgpDiPgmK02jq.pgp Description: PGP signature
