    I've had my Macbook Pro since December 2007 and only today I've noticed it suddenly getting hot when doing nothing but browsing forums on Safari, smcFanControl said it was up to a shocking 90 degrees Celcius. At first I just ignored it but it happened again just now but this time only went up to 75 degrees Celcius.

    Anyone know what's going on?

    EDIT: iStat say's it's the GPU Diode getting hot.

    1. Monitor CPU usage under Activity Monitor and make sure All Processes can be seen.
    2. Flash, good lord Flash.
    3. Reset SMC and PRAM.

    Have you looked at Activity Monitor what process might hog up the CPU/GPU?

    Don't forget to show All Processes.

    If it happens when randomly browsing the web, it's most likely Flash--pretty much any Flash animation on a page will peg one CPU core at 100% and drive the temperature WAY up. Since Flash ads are everywhere, that's probably it--got so bad I eventually enabled FlashBlock.

    I wouldn't expect that to be hitting the GPU nearly as hard as the CPU, though. If the aforementioned suggestion to check Activity Monitor shows your browser at or near 100% CPU, then it's definitely Flash, though.
