    Hi everyone

    I have a MBP 13" early 2011
    Lion 10.7.3
    2.3 Ghz i5

    It is incredibly hot and sluggish at times

    Just a while ago I was importing some photos using iPhoto, and the computer became pretty slow, often freezing and was quite hot... 90+ celcius !! - Screenshot of temps and hw stats

    Some background programs running were just MS word, Adobe reader and Safari with a few light-weight tabs open - Screenshot of running programs

    Isn't that temperature incredibly high for performing such simple tasks?
    The current room temp is about 25 celcius


    I went to the Apple Store and the staff told me his MBP was running idle at 90+ celcius, incredible and unbelievable. - Two weeks ago

    Also, when running Flash, the temp stays at 90+ and performance is insanely horrible, freezing very often. Especially on Tetris Battle (Flash-based game on Facebook)

    Flash has been updated to the latest and I don't have many 3rd programs installed/running.

    I'm going to update to 10.7.4 tomorrow but according to the changelog, there doesn't seem to state any fixes related to my problem. OR is this a common problem(temp)?

    Also, I'm using it on a flat surface table with 25'celcius room temp, no vents are blocked
    Right now, there's not only a heat problem but a slow-performance prob :/

    Thx for reading guys

    Dude! That's messed up! Look at Apple's specifications for what the thing should be running at:

    Line voltage: 100V to 240V AC
    Frequency: 50Hz to 60Hz
    Operating temperature: 50° to 95° F
    (10° to 35° C)

    Storage temperature: -13° to 113° F
    (-24° to 45° C)
    Relative humidity: 0% to 90% noncondensing
    Maximum operating altitude: 10,000 feet
    Maximum storage altitude: 15,000 feet
    Maximum shipping altitude: 35,000 feet

    That raises some red flags to me... You might wanna have the thing taken in or looked at, that's certainly not normal at all.

    Operating temperature: 50° to 95° F

    The Operating temperature is to do with the ambient room temperature.

    Try resting the PRAM Resetting your Mac's PRAM and NVRAM . That probably won't fix it, but you can try anyway.

    Try reinstalling your EFI and SMC updates. SMC firmware controls your fans. Find your model in the list: EFI and SMC firmware updates for Intel-based Macs

    Resetting your SMC: Intel-based Macs: Resetting the System Management Controller (SMC). On of theresaons for resting is listed as "The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated."

    Definetely update all your software and keep it up-to-date.

    If you feel up to it, when you are reseting your SMC, (you have to disconnect the battery by removing the bottom of your MacBook Pro; easy to do!), check for dust build up and clean any found.
    Until the next time… And if I help you out, give me a "Thanks!" Thanks!

    Are those actually flashing a firmware/rom?

    Would it be risky?

    Yeah, you are basically re-flashing your firmware and OS X may not even let you. I've never had an issue.

    But I'm not that savvy and would prefer not to take any risky routes.
    Maybe I should ask the Apple store guy to check if the vents have dust in it first

    Taking the bottom off your MacBook Pro is super, super easy. Flip the laptop over on a table and remove the screws, placing to the side, lined up with their matching screw holes. You'll see the fans. The battery connector I above the battery. Its a small connector about half and inch wide. Disconnect that and follow the SMC reset instructions. Honestly, it'll be hard to break anything! Have a go!
