    Should I be able to feel the airflow coming from the fans somewhere? When I put my fingers right between the unibody and the screen at that gap, I don't feel anything.

    That depends on the fan speed. The fans or fan spin or spins from 2000RPM (minimum) to 6000RPM (maximum).

    How fast are yours running? iStat Pro (Dashboard Widget) can tell you.

    No, and if you do, it should be very minimal and it only happens when the fanning are spinning fast.

    Well since my MBP wont automatically change fan speeds, I have it manually set to 3500rpm. If I don't turn on smcFanControl, it is always stuck at 2000rpm, even if the temps go past 170F. The temp reading is kind of strange. When it's really hot, it will go back and forth between 155F to 175F.

    Where is the air escaping from? I just am a bit paranoid that my notebook isn't ventilating correctly. At least on my Envy, I can feel the air being pushed out.

    Added: Just now the temp reading went from 118F to 151F back down to 113F. I notice that it goes higher when I look at a certain webpage.

    Chances are those websites have flash ads or something.

    Don't worry about your computer, it will be fine heat wise.

    Yeah I was looking at flash ads, but why would it raise the temp so much?

    Flash is highly CPU intensive, watch a YouTube or other Flash based video and have a look at Activity Monitor.


    image below uses sorting by CPU as an example

    Flash and Macs do not play so well together. :eek:

    Perhaps this is why Netflix makes the temp rise so much also? I don't notice the same temp jump on my Envy. What is the difference?

    Hopefully the new update to flash should help with temperatures Does anyone have a list of what grApchis cardsz are supported

    Yeah, that is the exact reason netflix does it too. Don't pay so much attention to the CPU temps, you'll be fine.

    Thanks :) I just wish it wouldn't make the notebook so hot!

    Don't worry man, that's not overly hot for the MBP at all really. In fact, your computer should be able to get up above 200 F before the fans really kick in. I used to always be worried about it too, but now, I just let my computer do what it wants to, it'll take care of itself :D
