Sorry for the poor explanation... Yes, the fan still spins all the time, but it's slower and quiet now (at normal temperatures). I have to put my ear next to the machine to notice it now, so although it's still happening it doesn't really bother me anymore. I haven't tested it under heavy load yet, but I assume (hope) that it will spin faster when the system actually heats up.
Dimitrios,

As far as the latest bios goes, I followed the instructions at http:// linux.dell. com/wiki/ index.php/ Tech/libsmbios_ dellBiosUpdate. The "System ID" for my 1420 is 0x01F3 and the latest bios for that is A09. If there is a newer one somewhere please let me know.
