    I'm having problems with my pre-UB (2007) MacBook. I get kernel panics every time I turn it on for more than a few minutes; it seems to be heat related, because it gets hot even when not doing anything and the fans rev up to max, but iStat reports max CPU temps in the 60-70 degree range, and CPU usage maxing out around 10%.

    I figured that I had everything off of there that I need already, so I decided that I would reinstall OSX using the restore discs, but it KP'ed during that as well, and now I can't get anything to load, because it's already gotten part of the way through the install process. I had already tried resetting the PRAM, but that didn't do anything, either. I'm running Leopard, and the only change I've made to the computer is the 4GB RAM kit I put in it the day I got it back in 2008.

    I guess I can't pull the log, since I can't boot my computer. What do y'all suggest?

    have you recently upgraded ram? If not it could still be a ram issue, maybe a faulty chip. If you have access to some try swapping it out and see the panics still occur.

    The temps do seem a little high for idle. I have a mid 2009 macbook and I idle at 48-55*C depending on how long it has been on.

    It fairly simple to take of the top casing, give your fans a clean and re grease your cpu. Guides can be found on ifixit, its about a 15-20 minute procedure depending on your skillset.

    Yeah either something is bad or is full of dust. But even after an year of use my macbook was full of dust:( so you should clean up the cooling system.

    It kinda came on all of a sudden, but I don't really have anything to lose by opening it up to clean and reapply the TIM. Project for next day off!

    The RAM is the same as it's been since I got it, though.
