    The top left side (looking down while opened) of my Macbook Pro (Unibody 15") heats up a lot even if I'm just surfing the web. I don't have any apps running in the background or even that many tabs open. This is my first Mac and I got it about a month ago. Is this normal? It does it a little more when its not charging.

    Install iStat Pro and you can get some temperature readings so people can tell you if they are normal.

    Depends on ambiant temperature, what gen MBP, what size, the newer ones have two GPU's(in the case of 15'' and 17'') and etc.

    I have the last generation before the unibody came about, and I usually idle around 50*C.

    In iStat Pro which temperatures do you look at and/or display on your menu bar. I've installed the software but not sure what temps to display - thanks.

    CPU Temp is what you are looking for.

    Core A or Core B.

    160F is on the high end of things anything under that is normal.

    Seems high – what are you running in the background when it's idling?

    Are you sure that's Celsius? It's not Fahrenheit? :)

    Mine usually idles around 40-55c depending on how much apps I run. Right now, it's at 45c running firefox, msn, tweetdeck and itunes. Sometimes when im lying on my bed it'll go to 80c when im watching a movie. I just turn up the fan with smcFanControl. I keep it at 4550rpm but when it gets around 70c+ il up to max 6200rpm

    Averaging 65 Celsius here with C2D 15" MBP 2.8ghz, 256ssd.

    With 20 or so Firefox windows open, charging iPhone, Chrome, Pages and Evernote as well.

    It that a good/average temp?

    Edit: I'm running on the warm side, the i7's are running cooler.

    Question: Will the i5 run cooler and have longer battery life than the i7 or the same?

    Mine's idle from 50-60 degrees. However is it normal that the left side of the mbp (2010) is warmer than the right? If you place both hands on each side of the speakers (15"), the left side is warmer considerably. Is because the CPU is located on the left side?

    /the rest of the world.

    anything between 40-60 C idling seems to be the norm.

    I'm also having heat issues with my Macbook Pro ( spec in signature )

    It's running at 70 degrees celcius with Safari, Mail and iTunes.

    When I have ArchiCAD opened it runs at 90 degrees C and when it's starting to render, or using photoshop it runs upto 105 degrees C and have on a few occasions reached 106 degrees C !

    I'm also having constant crashes, the whole enclouse is extremley hot and overall the computer is slow... I've now sent it to a Apple Authorised service provided ( through applecare, group 8 UK ) for inspection... If it comes back with any of the above issues, I will be asking for a replacement ( they put me straight onto level 2 support when I told them what temps I have and said that an inspection is needed before they can offer a replacement ) I also spent 2 hours on hold with them whilst they transferred my HE Applecare to this machine although I was told it was transferred before Christmas 2009 !

    But hey, I know Apple will take care of me :)

    EDIT: I'm using iStatPro

    100% sure its C not F right now idling at 64C if I had to guess I would say its about 70F in my bedroom and if it helps my computer actually has great air flow ( sitting on a mStand )

    I thought those were normal temps lol

    Also I only have this thread open in safari,mail, and transmission open. thats it.

    (note: my computer runs pretty much 24/7 ) but right now at school after just taking it out of my case and turning it on ( it was on standby ) and using it for about 10 mins I have a temp of 35C
