CPU Temp/Fan Issue

    Hey guys, I just got my first Apple computer a few days ago (MacBook Pro 13" Late 2011) and put a Samsung 830 120GB SSD in it within a few hours of playing with the computer. My issue with the MBP is not that it's slow or crashes having to do with SSD. In fact, the MBP boots up in 11 seconds tops and launches applications even faster.

    Anyway, my problem is with the fan. Coming from a windows laptop, I haven't come close to hearing the fan this loud (I don't do gaming). Within the last two days, I've heard it go up to 6000 RPM more than 10 times. The first time was when I was clean-installing Lion on the SSD using the internet recovery. Then, the second time was when I was updating lion and other programs on my first software update. Other times, it's watching a flash video or HTML5 video on youtube. Just recently, I saw iTunes take up +100% CPU and had to quit the application because the CPU was 82C and the fan was at about 6000 RPM. Upon quitting the application, temperature dropped within seconds. (For reference, my idle temp sits around at 52C).

    So, my question is whether I have a problem with the SSD or this is a problem with my MacBook Pro. Or rather, is this all normal. I'm especially disturbed by iTunes making the CPU usage spike up so high.

    Sounds normal to me. What was iTunes doing when it was taking up 100% of the CPU?

    It was playing a song. That was it. No burning CD or downloading. That's the weird part. I went ahead and quit the program and restarted it to see if it would happen again and it didn't.

    So it is normal for fan to crank up when installing Mac OS X on a new drive or installing OS X update?

    Since you just installed it, was the system still indexing Spotlight?? That will happen for a while after a new install and can bring even the most robust computer to its knees.

    More CPU work = more heat = faster fans.

    iTunes probably got into an infinite loop or something, but apart from that, stop monitoring your temps and fan speeds, it's useless to do so and your temps and fan speeds are normal.

    yup... Integrated GPU = More heat.
