2012 15" Retina Display MacBook Pro Overheating!

Mine is new and having read these threads when considering buying it I would say compared to my last MacBookPro the keys themselves are warm -- I am wondering if there is not a difference in:

1. pixels used

2. flash memory as opposed to hard drive

3. new fan design

The fan kicked in after the first 20 minutes and it is now cooler. I agree, hot/overheating -- these are all relative terms. My old regular MBP ran very hot so I couldn't really put it on my lap, but the keys were not warm.

Hey -- good for cold weather?

I'm having same issue and already replaced one macbook pro retina with another, using smsFanControl to keep temperature down, but little bit amazed apple let this go to market like this. It's getting hot after about 10 minutes of just browsing internet so its not like heavy video editing is causing it.

Hello DS Store , i would like your opinion based on your answer in this post>

A:Could be a dead sensor

Q:Do you think a dead sensor is responsible for a MBP 2011 to make the fans work more than normal, ex. 3100-4100> after dead sencor > 5200-6200, and do you know how easy is for a MBP sencor to be melfuntion,meaning to stop working.

I will give a little background of what happens to my MBP as well my i think a dead sencor might be the problem for me.. First of all I have a MBP 2011 early.. with an SSD i have my MBP 1 year now and i live in Greece when i played for the first time a 3d game the fans were silent 3000-4100<(a bit noticeble) the temps were low 45-60C.

I then tried a 3d game (DIABLO 3) the fans started to work at 6200 constant all the time..{tried D3-BETA for 3 days). then i stopped playing any 3D and Reinstalled LION...... In Greece the temps are high 30-31C day my mac heats a bit more during day operation, now i come to my question why i think a sencor might be the problem, i place my mac on my deck with nothing on just my MBP and i abjest the AIR-Contision Cold are to hit cold air on top of my MBP keyboard!! At night time the temps are not the same as day, thus the fans do not work constant for .ex when i play a 3d game, they are normal, and i can barely hear them.. but when i move away from the air condition the fans start to increase in scales for ex. 2200-3200 noticable and then hit max 6200 and spin at constant speeds again. This is very strange do you think that all this might have happen when i first played D3 and as a result the constant fan speeds inside the MBR to caused a problem to the sencors?

well, i had this issue and got my macbook replaced more than a month before now on july 6th exactly... anyways, what does ur smsfan read as temperature wise? my fan stays at around 233-2500 rpm, if i doing facetime or something it even went to 4300-4500 and it was very hot but the funny thing is that my temperature on the sms fan data stays at 32 degrees fahrenhiet or 0 degress celsius... that doesnt make sense... i feel like something is wrong with my sms fan data as well?

Any input on this one?

And yeah if ur macbook gets hotter just by 10 minute of browsing you hsould replace it.. thats abnormal.

So this doesn't always happen, but sometimes does and is really stupid and troubling. I shut it down after work, and put it in my briefcase. I then went out for the night, and when I came home, I reached in to my bag and the entire bag was physically hot. My sleeping MacBook Pro retina was fanning itself full blast, even though the monitor was off and it should have been asleep. Why is it overheating and running the fan when it should be blissfully asleep and staying cool? And if you're a closed laptop computer, why would you run your battery trying to cool yourself? It's kind of like selling your own stock when it's low, instead of buying it up using your ample cash stocks. See one makes sense, the other does not.
