    So I'm trying to make sure I don't let this thing get hotter then it needs to.

    The two things on the sides I can leave unblocked. Are those inputs or exhausts for air though?

    And the thing under the display- input/exhaust? And I can't tell, does the air flow about the black par on the display, below it, or both?

    I'm trying to tell if I'm in bed and have where the display and bottom half of the laptop meet touch the sheets, will that be blocking it? Aka- does the ventilation come out the bottom under the display too?

    Fortunately I have no desire to use mine in bed.

    Sides are input and the thing under the display is the output.

    Check out the promotional video on
    At 3:20 it shows how the cooling works.

    Intake on bottom, exhaust under display... This is most obvious thing

    Ok well even if I'm not in bed, if I'm on the couch with a blanket laying down, will the blanket under where the screen and display meet block it or does it flow up?


    And thank you for a helpful, non sarcastic answer!

    It's hard not to worry about something that you've paid so much money for but don't worry about it. It's not going to overheat from being on a blanket with the ventilation blocked.

    Get something flat and rigid to put it on. Doesn't have to be anything fancy, just something to make sure it doesn't sink into the sheets. A plastic cutting board - a cheap serving tray. Anything that the same size or slightly larger. Of course if you're going to lie in bed with it on your stomach, get a decent laptop tray or whatever they're called with some padding on your end. You'd want it for the heat in any event.

    Ok thanks!

    So the venilation does come out the bottom as well?
