using macbook retina (full load) on bed and temperature results :)

Well , regardless of people saying dont use it on bed it will block the air vents on ur machine, I thought of giving it a go...
I noticed when im placing the macbook retina on my bed, it doesnt really shut the air vents and if so, just barely...
When I was running world of warcraft on the machine being on my lap, the GPU tempeture was at average of 65-67 degrees celsius. when running the game while laptop placed on bed, average temperatures were about 73-75 degrees celsius.

my question is this, can 75 degrees celsius be that bad for the insides parts of the laptops ?
I remember gaming on my alienware m18x with two cards heating up to 80 degrees celsius... and that was considered normal.
I also heard that apple inside parts can handle heat allot higher than 65-75 degrees celsius.

I remember the razer blade laptop I owned using to get as hot as 80-90 degrees celsius and the tech guy said on phone that parts can handle up to 120 degrees celsius without a problem... and that was a GT555m GPU.

 

its not only about possibly blocking vents, but that placing a heat producing object on a surface that retains heat, keeps the whole thing hotter. You need proper Airflow around the unit. I'd be more worried about CPU and other temps... were your fans running at max speed? you can lay it on your bed, just get something hard and flat to put it on.

 

The mbpr vents are on the sides of the unit. I'm not sure how you decided you were blocking the vents by putting it on your bed, but you should take a second look at the bottom of the unit, and at the vent location.

 

usually when u put something on ur bed ( lets say about 2kg) then it sinks down a bit thus blocking the vents on the sides, but not 100%.
what do u mean button/ vent location ? under the screen ?

 

I never used the term "button".

I'm talking about the bottom of the unit - the flat surface with no vents, versus the sides of the unit where the vents are.

If you only cover the bottom of the unit, where the vents are not, then the vents are not blocked.

 

a soft surface that retains heat will make the laptop run hotter even if its only on the bottom and not blocking any of the vents...

For the record... the rMBP intake vents are on the lower bottom sides (kind of more on the bottom than the side, but on a curve), and the exhaust vents are in the screen hinge like previous models.

 

auto grammer correct changed it to button for some reason, but i meant buttom




do u think that a thin hard plastic surface should be enough or preferred none plastic material ?

 

A hard solid non insulating surface would be better. Remember blankets insulate heat to keep you warm and this concept applies to your laptop - heat that would escape through the bottom is insulated now.

Though I don't believe it would harm the laptop.
