Originally posted by brofkand They aren't passively cooled, but they do get warm. It's a side effect of using high-performance Intel chips in a very slim and lightweight enclosure.
If HP or Dell had an inch-thin laptop with everything inside it that Apple puts in their machines, they would be just as warm if not warmer.
Err, um.... they do! I have at least two laptops under an inch (not counting the screen); one when removed from its dock is quite thin. No doubt the Mac is sleeker still. but...
Which CPUs do they use? I don't usually find that sort of thing that readily available from Mac; tho I admit I only looked into it once.
It really can' t have to do with the thickness -- a WinTel PC with the same gen Intel CPU as in a Mac will dissipate the power from the CPU the same amount for the same number of MIPS used -- but rather with how diffuse the ventilation port is. My IBM X61 is much hotter in the lap than my Dell E6500 [w/a T9400] for example, even tho the CPU in the E6500 dissipates more power than the one in my X61. The X61 has a much smaller vent. In addition the X61 not being as wide the vent will sit on the inside of the thigh in my lap; the E6500 on the outside. So I don't feel the heat as much from it.
@Ex Finn. I feel your pain. I have monster cabinet, dual core AMD CPU, with dual NVidia GPU, all water cooled, that is pretty much only on par with most of my current laptops... which I never use anymore since it's inconvenient to be @ my desk to use it. ...lol.
