Besides, it's none too flexible - sometimes just one of the conditioners goes down, so the room temp gets to, say, 25C, but that's still not a reason to panic if the situation is under control. And even when bunch of bioses shut system down all the systems correctly because of cpu/chipset heat when A/C dies, there'd be a lot of hard drive failures in a few weeks. --=20 Mike Kazantsev // fraggod.net --Sig_/FMV+=jUYSrAkDVYPyESL8nu Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (GNU/Linux) iEYEARECAAYFAknFdk0ACgkQASbOZpzyXnFdKwCfSh7y6WJ7NPiu0TpvgulFLosz KzEAn3pzitOxnLTzi2wb8sebynL4YLKy =ztt/ -----END PGP SIGNATURE----- --Sig_/FMV+=jUYSrAkDVYPyESL8nu--
