Extremely hot MBP-R in Win7 (bootcamp)

I have to just say thank you! This helped me and I recommend others to try this if you're experiencing high CPU temperature while the laptop is idle or has low CPU%.

It's clearly a bug and this solved it for me after attempting to install the latest processor/graphics drivers and running diagnostic on the processor (which passed the test).

It did not make any sense for the CPU to heat up when the CPU is only reaching 20-30% and especially when it's idle.

Thanks again!

This heat and lack of thermal fan control is the weakest point and has been an issue for as long as Windows on Mac and Boot Camp and is not right. It is not normal. But there is no equivilent of "SpeedFan" so in that regard it is what it is. Unaddressed and reason I stopped using my Mac except for light things that the slow default fan can handle. And built a PC for everything else.

Same for me on my rMBP (2,3GHz). Within 30 seconds from starting the game the fans kicks in and the temperature raises. I was playing Deus Ex while monitoring the temperature. When I tab out of the game the value is around 80 degrees celcius but if I played more than 10 minutes the maximum value is 100+ degrees.

Since the computer doesn't shut down I don't think it's a problem but on the other hand, it can't possible be good for the computer to run at that temperature. Often when you're playing games you'll be doing that for several hours. It can in no way be seen as an unusual usage of a computer to play games for a few hours.

I also have a MacBook Unibody that went so hot that the battery swelled (melted and expanded?) and I wasn't able to close the cover of the battery. After two years I needed to buy a new battery because of this.

Is this temperature the same for all rMBP users that is playing games?

Does the fan speed up and make a kind of high noise for all users?

Can you do something about it?

Is it likely that the battery, or any other part, will expand like in my old MacBook?

What temperatures does Apple say/recommend your computer running at?

If the computer breaks I assume the waranty would cover this, right?

Thanks

I would look at Intel and what you can find about that processor model on http://ark.intel.com and even then Intel does not publish everything for the public or in terms that are easy to decipher, the whole issue of what and how and thermal junction is it seems rather more complex.

There may be increased stress from how often and how much the temperature changes and the processor is subjected to over time.

Also I've seen reports of excess and poor soldering as shipped.

Give a processor time to break in and the soldering improves after a few weeks. Disk drives have start-stop cycles but running 24/7 at constant even temperature is actually less stressful. Fatigue from being subjected to hot-cold cycles with electronics.

MacBook Air 2012: There is a known bug with the upgraded CPU under Windows today. Turbo Boost is disabled under Windows on the 3667U, although it's fully functional under OS X. Apple is aware of the problem and I'd expect a fix at some point, but there's no indication of when. ANANDTECH

MacBook Air and MacBook Pro Update 1.0 (76.64 MB)

This update fixes an issue that can lead to increased CPU power consumption, and it improves compatibility with some USB devices.

Products Affected:

MacBook Air (11-inch/13-inch, Mid 2012), MacBook Pro (13-inch, 15-inch, Mid 2012), MacBook Pro (Retina, Mid 2012)

Additional Information: This update is recommended for all Mac notebooks introduced since June, 2012."

Thank you for your reply The hatter!

I read the Wikipedia article and it seems like this is the way temperature is calulated in the program in Windows. The other possibilites is that Windows is showing the temperatures wrong or that Boot Camp has some kind of bug that makes the temperature that high.

I just played som L4D2 from within OSX instead and when I did this on highest settings (wich should be about same as Deus Ex on medium) the CPU gets 61°C and the GPU gets 68°C (GPU Diode is 72°C). Other parts seems to have a more reasonable temperature where the enclosure base is ~34°C, the memory modules 58°C and HD is 41°C.

Regarding the MacBook Pro Update 1.0. It seems to be for Lion or earlier releases. Since I'm running Mountain Lion I cant run the installation.

Anyhow, hopefully there will be some updates to Boot Camp so that this issue is resolved. What's annoying is the noise from the fans but I assume that's better than an overheated computer. When I played L4D2 the fans spun at 4622 and 4985 rpm.

I actually thought without having MacBook, that update 1.0 was EFI firmware update and OS agnostic.

The kernel can also patch microcode, device issues and other bugs as well as firmware.

If you have been following my posts, I recommend AIDA64 to monitor hardware - gives you a lot more information and is constantly updated to reflect the latest changes and processors etc.

I believe I recently read on endgadget? that a large portion of the heat is due to use of the dedicated video card - that the bootcamps' drivers for Windows can't use the intel 4000 graphics, but only the dedicated GPU, driving up power consumption and temperature.

3rd Generation Intel HD Graphics 3000/4000 Windows 64-bit

I would like to chime in here, and I am sure it has already been said, but I got some information that I thought might help in this situation (and I looked everywhere for a solution).

If you're running bootcam and primarily relying on programs that will utilize the gpu, you can go into your power management settings, go into change plan settings, advanced power management, and then open the processor power management tab.

Here you can throttle your cpu down so it doesn't ramp up and turbo boost with every intense application.

I comfortably run FFXIV at right around 70C with Lubbo's running my fans right around 2200 rpm. Obviously this scenario only works for those using bootcamp for games and such, but it definitely keeps the computer much cooler.

As far as performance goes, it performs comfortably well on my 2.7Ghtz retina, I am sure I could push it further, but that's not why I want to game on my laptop. I have a pc desktop for power.

Anyhow, thought this might help some still struggling to keep their uber expensive mbpr cool durring windows gaming.

Cheers,
