So I've been reading through the reads about fan noise issues and this being my first macbook pro I've found myself a little paranoid so I'm wondering if somebody could clarify for me what's normal and what it isn't. I just got my macbook pro yesterday (2.8 ghz 320 gb hd @ 7200) and I've installed 32 bit Windows XP. When running XP I've already noticed it runs a bit warmer than in Mac OS and while I haven't found a working monitor yet in windows, in Mac OS the CPU sits around 52 C. In windows, I've noticed some fan bursts occasionally when applying updates. All of this didn't really bother me until I read people describing their computers as "dead quiet." Is that an exaggeration or should there really be no detectable sound? I find that I would never quite describe it as being "dead quiet" though the sound it does make a large percentage of the time isn't detectable from more than 2 feet away. I should note that now that I've switched to Mac OS X it seems to be cooling down to a better running temperature than it was in Windows. Has anybody else noticed excessive heat in Windows XP 32-bit? Again, I feel like I'm being paranoid but being as much of an investment as it was I want to make sure everything's perfect.
