Yes, as only the RAM is powered and the CPU and GPU are the parts getting hot. But there are also the fans which will cool down the CPU and GPU, so there is no real need to put the Mac to sleep.
 
Yes, eventually. I put my MB to sleep after a long session and after about an hour it had completely cooled down. This is because the computer is barely running, so the things that get hot like the CPU aren't spinning as fast so they don't get as hot.
 
Lord knows when your CPU is spinning faster than normal, you have a problem on your hands.

XD
 
would u guys know if this is true for bootcamp windows 7 too??? Im not even doing anything intense but streaming video and it gets really hot and goes into sleep mode.

Ram gets hot as well.

Boot camp/Windows 7 doesn't support gpu switching; it'll run the nvidia gpu full time... turning the lappy into a hot plate.
 
ah ok, so do u think this is the reason for it going into sleep mode?

thanks.

I misread your question, I read it as "Will putting the laptop to sleep cool it off" not "Will the laptop put itself to sleep to cool off"

There is thermal shutdown protection... but that shuts the computer off.

In sleep RAM still only gets the sustain impulses. That is some 200-400 mW. That is really very very little. From a thermal perspective there is no difference between off and standby.
