Macbook Pro Retina heat issues?

Hi,

You can directly manipulate the fan speed by smcFanControl which is updated for MBPR and I always have this open to see the both temperature and fan speed.

But in your case, you should first find out why your machine needs that much cooling system. First do SMC Reset to see if there is a bug or something else. If it happens again open up Activity Monitor to see if there is any task that hugs the CPU and make your machine run hot.

SMC Reset:

Fans

The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.

Yes, yes I am. Brand new MBPr. The CPU usage is around 25% and I can't keep my fingers on the keypad. It burns. And the fans are blowing quite hard. Strangely most of the time the fans won't even run and the machine is very hot. They could work a bit sooner, I think...

Also I can't use this as a laptop, since the heat is so bad my legs are going to be burned too.

So I'm not going to keep this machine, but I'm not sure how to get it returned. It's impossible for me to work with if at 15 minutes of 25% CPU usage I can't even type with it. What will it be like when the CPU usage hits 50% or higher? Or if I happen to use the GPU for something (currently the machine is running only CPU/disk based operations). Completely unusable machine for me. But hey, that's Apple. "Let's put a high power CPU into a tightly packed machine, nobody will ever use it for anything anyway but it'll look good on the spec sheet!"

If you are going to export or render videos/3D all the time or even play games on discrete graphic card BIG yes it's gonna burn into the ****!

Yes, if it was all the time and that usage, I'd understand it getting a bit hot. But do note: I was only using a quarter of the CPU, the GPU was not used at all and the time was limited, not all the time. And still the CPU housing went up to 92 degrees centigrade, disk to 55 and discrete GPU was in use and went up to 70. That's not very good design. And mind you: the GPU is not used in what I do (database handling etc, only CPU and disk).

Just to compare, my trusty old Dell can handle all that I'm doing (a bit slower since it doesn't have SSD or i7) and I can still hold the machine on my lap and my hands won't be burning. And I'm sure most of the machines out there would too.

I went to buy MBP 15 inch Retina as well but I can feel the burning heat on almost all of the the running MBP Retina Display in the shop which they told was running from last 2 hours.

This was quite a alarming one for me to buy this and decided against..I am happy with my Sony Viao 🙂

ALL THE BEST!!

my NVIDIA goes up within 30..60 seconds to >70 °C.

I assume I also have to exchange it.

Same exact experience with my two month old MBP retina display running 10.7.5. Super hot after about 2 hours in sleep mode in my carrying case, almost too hot to touch, but cooled fairly quickly once I took it out of the protective sleeve and opened it on a table. Battery had also run down from 100% to 63% over 2 hours. CPU usage low only running Finder, Safari, Word, Outlook. I am afraid to store my computer in the sleep mode. Other than turning off wake for Network Access (or just turning off the computer rather than relying on sleep mode), has anybody identified a way to prevent this from happening again?

davydany,

which app were you running to show the system status with various temps?

thanks!

Merry Christmas

Apple Care told me I should treat my laptop like a car going into the garage for the evening. You shut the car down so shut the laptop down. So every time, multiple times daily when I bag the laptop I should shut it all the way down, lest it overheat and melt my gel cap vitamin packs and my chocolate snack. Shame they didn't tell me this at purchase because I would have not bought the unit!

So perhaps this is the transition from a company where the top people used to listen to their consumers to where they become another commodity producer pushing crap out the door. So long Steve Jobs. Word of mouth will kill a company that used to respond at that level and now develop hearing deficiency.

I think of ISO 2001 certified organizations that have formalized customer feedback and corrective mechanisms to a level that an organization like Apple never needed because the head guy was so tuned in to the customer chatter that problems got addressed directly.

I wish I'd bought Apple stock years ago when they had the system. I'd be selling it now.

Who was that idiot person!? I have a base model with 16G RAM and I work with this machine like I never could work this way with my Mac Pro with that spec!

I don't have a problem with heat. I mean it gets hot but when I'm running windows 8 pro on vmware and developing Windows phone 8 with Visual Studio 2012+Blend!

So if you do nothing and it gets hot (smcFanControl shows 80dgress or iStatPro shows more than 70 degress) there is something wrong whether with hardware or software.

Go to Genius bar and let me check out your machine.

Good luck

Do you have PowerNap disabled in System Preferences -> Energy Savings -> Battery (Tab)?

Maybe this helps for your special incident.

Merry Xmas,

What tool are you using for analyzing GPU usage? Im am just asking, because Activitiy Monitor does not show up GPU usage separated (or: I just didn't find it).

For your help, many thanks in advance!

I have the same problem, CPU is only used 25% (over all 8 kernes average), but four kernels are quite fast above 100 °C and the system becomes stuck.

I already did a lot of analyzing and it seems it's specially a problem if the system is using the NVIDIA instead of Intel HD 4000.

I my opinion, there must be some hardware or design error in communicatoin between logic board and NVIDIA card.

I hope, Apple pick's up the problem and delivers a solution.

Has SMC fan control actually been updated at all, to support the rMBP? I didn't see a new version. I tried running it earlier on a rMBP but it didnt' seem to do much.

My fans seems to park at 2100 or so, even when say the CPU Die - Digital is at 180 F

Hi. My MBP Retina 15'' is working at very high temperatures. For example simple working on lap. (safari, itunes) at 3000RPM temperatures Cpu Temperatures stays at 60 degrees Celsius. And the worst part is that at rendering at Autodesk maya it goes and stays at 100-105 Degrees in Celsius and up to 221F . With both fans spining at 6000RPM. And i know that 105C is kind of limit for my CPU. So i am very carefull, but how can i work with that? When i take MBP on balkony in winter and then do rendering, with outside temp. -5C= 23F it stays at 92C. I am always using MBP in well ventilated room at ~20C. So is it normal? I think it isn't. 😕 Can anyone help with some tips?
