(MA701LL/A) Upgraded RAM to 2GB Running on Ubuntu 10.04 Lately Ive noticed that it heats up very easily just from routine use. Playing videos causes it to heat up to where it almost hurts to touch. Ive had issues before just months after I got it where I suspect heat damage caused it to no longer boot. I assume dust may be a factor, and possibly old thermal paste on the CPU. Being this old, it probably could use a good cleaning. Could that be all that I need to do or is there something else I can do to keep it cool? Also, if there is anyone who is good with linux/bsd that knows what works best with macbook, that would be awesome. I dont have the original reinstall disks so thats not an option. I wasnt fond of it anyway.
