Hi all, I mroogled for instances of the same issue, only found one from Oct., hope it's ok with a new post. Have a quick question about the temp's of the alu Macbook. The first few months I never heard my fans, and now they seem to run between 3k and 5k all the time (iStat)? They used to run below 2k. The CPU and heatsink temp's are about 79C, after running FF with like 2 tabs and Word - happens very quickly. Should I be worried? I know Macs run hot, but though these new ones were a lot better? Dust and stuff could of course be an issue, but I treat my notebooks quite well, and only use them for uni work. Have a desktop at home. No cosmetic difference. I actually have a very slight bulge in the middle, at the back. Scrapes along the table when moving it about. That's been there the whole while though... Thanks for any input.
