MBP & MBPr lap heat

This is true for all Mac portables:

Apple Portables: Operating temperature

 

I find my rMBP gets considerably warmer to the touch than my old air did. Not too surprising considering the extra power and massive battery though. I think the CPU actually runs cooler though - so the warm bottom is basically a sign of the heatsink being quite effective.

 

My Retina gets warm but not too hot playing games or doing video conversions. The highest temperature reported by istat is about 72C

 

Usually, the CPU and GPU are the two primary furnaces, with temps higher than any other component.

 

I think laptop is kind of a misnomer. Notebook is a better term, because it sets more realistic expectations. Pretty much any notebook computer, including the Retina, is going to roast your giggleberries if you use it on your lap. They have pads you can use to protect yourself from heat injury, I know I use one (actually it's a cutting board).

 

my rmbp runs a lot cooler than my classic did. of course if you crank it they all get hot. but basic surfing and file maint. i can rest it on my lap and is only slightly warm, where the same activites would heat up my classic.

 

I can use my late 2011 comfortably on my lap, but just for browsing and light app use. For anything heavy like gaming it's on my coffee table.

 

I could literally fry some eggs on my Macbook if I really wanted to. It's become a bit annoying, but I'm learning to have to compromise with such a beautiful machine. I think the design of the vents is pretty crappy if you ask me, but at least the machine looks like a solid piece of art work. I guess there has to be some sort of compromise.

 

my early 2011 is fine for browsing on my lap but im usually wearing jeans not sure how it would feel if i was wearing silk pants

 

My 2012 13'' MBP runs surprisingly cool, even when doing more than just web browsing. Never hear the fan, either. I've never gotten it to being uncomfortably warm on my lap, and I've had it there for a few hours on occasion.

 

I use an XPad. It's one of those products that's almost too good to be true.

Simple, high quality, silver to match, inexpensive & ultralight.

Not only does it allow good air circulation, but the grippy non-skid bottom makes using your Mac in your lap, or other uneven surface a breeze.

It does seem like the Retina runs a lot cooler than MBP's. I use this on my lap on the couch for hours at a time, every evening. Sure is nice and toasty when running games, but not painfully so. Rest of the time it's just warm.

 

You will also find this on high performing PCs. If you run demanding programs on any computer it will heat up. Desktops you don't notice it as much because it is not sitting on your lap.

 

I had a core 2 duo 15" MBP that scorched my legs and my new 13" ivy bridge i5 runs substantially cooler.

 

You photoshopped your lap? Please don't show us!

 

You really need to ask this in the MBA forum. IIRC, the 11" MBA can get noticeably hotter than the 13" MBA.

 

Your using it wrong. Apple does not sell laptops.

 

I'd rather not see it.

Probably would burn a hole through them I'm a girl who lives in jeans and hardly ever wears skirts. Probably just as well, as I'd say using the MacBook on my lap while wearing one might burn my lap.
