I love thermal imaging more than a Predator and almost as much as I love the new retina display MacBook Pro. So I made this little GIF animation with thermal images from Japanese blog IT Media, showing how hot Apple’s coolest computer gets under maximum stress.
The verdict: it doesn’t get too hot at all. The combination of its ventilation design and the absence of a hard drive seems to work quite fine.
In sleep mode, it doesn’t produce any distinguishable heat, napping at just 30.3C. Playing a QuickTime movie for 15 minutes only took it to 35.1C.
The machine only got significantly hot when pushed to the limit using Cinebench and other hardcore apps. Then it reached its maximum temperature: 48.2C. That’s when you need to get your computer off your lap or risk some toasted legs. [IT Media in Japanese via Cult of Mac]

























interesting, I have ano older mac pro and it gets hot.... Which is fine in winter and not good in summer or if i want children. It made me wonder why laptop makers don't put the main heat culprits behind the screen where it won't burn your privates and logically get more airflow. Apart from weight distribution I'm sure there is a work around.
Well most of that heat comes from the CPU and VGA, so it would take more bulk on the screen if they put it behind it.
This new Mac is impressive if those states are true. I have a mid 2009 13" Pro and it's idle temp is 55C and when watching a video on youtube it get up to 75-80C.
It's very clever how they put the biggest heat-maker in the middle of the keyboard where only your fingertips touch.
My old HP laptop had the CPU on one palm rest and the GPU on the other. It got pretty unbearable at times. It's the little things that count, where good design is concerned.
That's why they call them Notebooks instead of Laptops these days.
The battery is another culprit. When you plug it in to charge the battery heats up drastically forcing you to remove it from your lap.
Why not do a thermal on 100 other laptops while they are at it, why is this one so special.
Surely as a reader of Gizmodo, this question should answer itself.
Er, probably because it's brand new?
So "it doesn't get too hot at all", followed by "48.2C". Nice one.
Honestly, who writes this crap?
Or maybe just use a Flash-blocker, and watch the temperatures dive.
My RMBP reached 96C when i opened multiple videos in youtube and played all in 1080p resolution. Once i closed them the temperature is immediately back to <60 (in a min or so..). I used 'Temperature Monitor'
