First try vacuuming out the interior of the case, concentrating on the fan itself, then leave the computer on. A computer left on all the time will last longer than one that is started and stopped every day. Just turn the monitor off when you're not using it.

I've always wondered about that ... how much longer will it last? Thanks.
