I have a three month old Mini. It's been running quiet 95% of the time until a few days ago. All of the sudden, it just started running REALLY loud with the fan on full blast. I've done a SMC reset and checked for stuck print jobs - no luck. Even when idle or shortly after rebooting it revs up to full blast and doesn't slow down. It doesn't matter how few programs I'm running or how little the unit is being pushed. It's a 2.26 ghz with 4gb ram. I was using an OCZ vertex and swapped out the HD to the original Fujitsu. No luck there either. Any suggestions?
