Simple question. Do the fans blow the air in or out of the case?
out of course; I'm sure you wouldn't want to have a couple of fans sucking in a bunch of dust particles and whatnot into the chassis of your machine.
Do you not feel the hot air coming out the back.
To have air coming out of the machine it has to be sucked in somewhere. There are two fans, sucking in air from the top to blow out of the back.
i know that with my macbook it comes through the keys and out the back between the screen hinge. might be different for mbp's though
I most of the laptops that I have seen, there are two fans- one intake fan, and one exhaust. I am willing to bet that there are two fans in the MBP- intake and exhaust.
They suck in from the back middle and out at the sides.
So each panel at the back:
Out - Out/In - In - In - Out/In - Out
the fans suck air in through the keys and speaker grills... (i have tested this by blowing smoke over the top!!) and it comes out under the screen (at the back)
if you crank up the speed of the fans, you can feel slight air movement.
Are you an idiot?
Only if he inhaled...
Why is he an idiot? He just wanted to see, It doesn't hurt anything.
you bet wrong. I want my 20 bucks.
I didn't call him an idiot. What do I care what he does to his machine? But nothing beneficial could come from blowing smoke into a machine.
More of an idiot might be someone who suggests the intake to be adjacent to where hot air is exiting...? Curious does not make for idiocy in my view - although it sometimes makes for expensive accidents
You don't need to have fans to blow air in to a computer, the drop in air pressure caused by the fan blowing air out will create a flow of fresh air into the computer.
Obviously, using fans to blow air in is advantageous, because you have much better control directing the air flow over the crucial components.
What a strange question.
If the air only go one way, whatever in or out, we can just use the MBP to get a vaccum?
There could be multiple fans, some which pull air in, some which pull air out - or there could be fans that only go in one direction, and the question is which. Of course air still comes in, in order for it to be blown back out (or vice versa) but there aren't necessarily fans that do both in and out.
I am amazed at the discussion such a topic can spawn.
AS I said, there are two fans in the MBP. One for the CPU assembly, one for the GPU assembly. The airflow is top > rear.
