It occurs to you WRONG
I had 3 machines i7 15", all overheated as heII on browsing internet even without flash. >>Absolutely identical!<< Exchanged two times, finally gave up and returned them all. They all overheat, I don't know what you guys keep discussing here. It is indeed faulty design and not a good buy. Hang on until Apple releases another and hope that the new one will be better.

Just posted this discussion:https://discussions.apple.com/thread/3278062
It's something I figured out, and since then my Macbook has be running a lot cooler. I used to run flash and get to 90c sometimes.. now its ~60-70c.

Here is what i did...
1. I have purchased iStat Menus 3. I deleted it, cause it continuously monitors everything and ABSOLUTELY was causing a temp increase.
2. I deleted from Login Items, Dropcopy, Skype, Dropbox, iStat Menus 3, great improvement!
3. I installed the Click2Plugin extension. Now flash contents are disabled and my Mac feels a lot happier!
All these caused totally a dicrease in temp ~8-10 degrees Celcius.
I also read the post of the dead (Thenecron) above...
System Preferences > Energy Saver > Uncheck Automatic Graphics Switching.
What happens (from my understanding) is that to conserve power, it uses the CPU to do the work of the graphics card, and of course is rediculous when running HD flash vides and such. Unchecking it will force it to always use the GPU. Which, takes a heavy chunk off that CPUs load.
I am not quite sure that your understanding is right...It is not the CPU that does the job but the Intel Graphics Card on it. This does not cause what you explain on your post but switching the graphics saves only the energy if you are on battery...

Well i may be a bit wrong. Is it still part of the i7 chip? Or is built in mean built into the motherboard? I have a GeForce card also, and when disabling that item in the energy saver, it kept it cooler. When it used the intel gpu, it was running 80c+. When i switched to the GeForce card, its at 60-70c.

I would suggest downloading the free SMC FanControl...if you already have'nt. It lets you manually set the fan speed higher while you render. I don't especially like to have to do that everytime I render but.......what choice do I have at this point?

No, Thenecron, you are absolutely right. It affects the temperatures because the chip is actually inside of processor chip. The guy doesn't know what he is talking about. And for end user it's still a physical processor overheat, doesn't matter which part cases it.
But your solution isn't a good one. Many people buy MBP because of battery life and you are suggesting to disable this feature which will cause 50% time on battery decrease. Makes no sense.

Yeah, i know it defeats the perpose. But the rediclously high numbers for battery life is when running without wifi, and etc. It almost seems like it doesnt swap between the graphics when enabled... though its supposed to.
I love the look of macs, and i love the OS. But its quite dissapointing that i cant watch a video without it being hot as ****. I cant play any computer intenseive games, i cant do anything really. This laptop is (when bought) 4,000 dollars. Its...for the most part, a waste of money.

For the third time, I took my 2011 i5 macbook pro to the genius bar.
Explained the issue again. heating + loud fan.
The gentlman said that he will have the fan replaced. I also asked him to have the thermal paste checked.
What they did actually slitely reduced the fan activity. Maybe it's just placebo effect, I don't know.
For sure, this Macbook pro reminds me of my Dell Latitude D630c.
Not sure if you guys heard about this

Actually, the Dell issue is similar to the one experienced by victims of nVidia GPUs in early 2008 MBPros (including me). However, it is unrelated to this current overheating problems, which is all Apple's fault: sticking new hot-running Intel i5 and i7 processors into cases designed years ago for chips that run much cooler.
