Agreed, but it's important to make sure you have the right balance of fans blowing in vs. blowing out. Most PC chassis have pretty poor "non-fanned" venting, and it's almost ALWAYS in the wrong spot. People tend to install fans so they blow out (it's quieter), but having too many blowing out can actually help things heat up, as the fans end up doing extra work trying to suck air in from vents that don't exist. =20 In my opinion, you want to try to have a little more pressure blowing in than blowing out - this makes the whole thing a little louder, but forces more air to move around inside the case (cooling things), and helps a lot in keeping the dust factor down. Plus, it lets you decide WHERE the air is coming in from, resulting in a lot fewer crap-clogged venting inlets. (I have several cases here that I've cut an extra 3" round hole in to add high-volume inward-blowing fans. A bit louder than normal, but the insides of these machines are really clean (I smoke), and the case temps are just slightly above room temperature.) mike --+B+y8wtTXqdUj1xM Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (GNU/Linux) Comment: For info see http://www.gnupg.org iEYEARECAAYFAjrAPyoACgkQJol4I8h9Gd+U2wCcCpnhzP9xQeW79XFAyWmPG1Rb rx8AoMjudWz6c6PxHk5a+Jst2yHYZk0m =90Bk -----END PGP SIGNATURE----- --+B+y8wtTXqdUj1xM-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
