well some specifics about what type of computer/case/components would help alot... or actual temperaatures. They do run warm... but sounds like you just need a few moree fans. Everycase should have a fan on the front panel (below the CD drives, and on the back. Simply and intake fan and an exhaust fan. Cheap fix depending on your case, buy a couple $3 fans on newegg or ebay and put 2 in the front blowing in and 2 in rear blowing out.
