So lately, for some reasons, every little thing that I did on my MacBook caused it to heat up and the fans to spin up. Before, I would be able to use Photoshop and have Firefox open with some tabs (no flash based websites) and it would be fine. Now, I can't even have Photoshop open, and god forbid I start editing a photo... the thing will get loud and hot. Right now, I have 3 tabs open in Firefox (they are 3 separate forums including MR), Mail, Adium and TweetDeck and the laptop is hot and the fans are spinning. It all started when I installed Snow Leopard and it gradually got worse over time. Things I tried to remedy the issue: Reset PRAM Reset SMC Blew out the fan Any other suggestions? What could be wrong? I would call Apple but I don't have phone support.
