I called them up one day and told them that my MBP is getting really hot.. They first told me some stuff about it being a notebook and not a laptop and so it is normal.. I told them that the system is running at 65C and i cant keep it on my lap at all. Also I told them that whenever i turn off the screen alone without making my mac go into sleep, it cools very fast.. then they put me on with a product specialist who arranged the repair right away..
Got a tip for us?

OK, So I just loaded Motion with 25 HD resolution particle emitters and ran it for 10 mins...
These are the results ;
Graphics processor Temp Diode : 78C
Graphics Processor Heatsink : 70C
CPU A Temperature Diode : 78C
Main Heatsink 1 : 63C
Main Heatsink 2 : 44C
Main Heatsink 3: 51C
Enclosure Bottomside :33C
The aluminium bar behind the keyboard is VERY HOT as is the centre underside behind the battery.
Is this something I should be contacting Apple about or is it to be expected ?
P.S : Update : After stopping motion it's back down to 54C in about 2 mins...

I had the exact same problem!! But my temperature never reached your record levels!! I'd say call dem now b4 ur notebook melts..
anyway if your MBP is still under warranty, when u call dem make sure u dont have any app running coz they will just tell u that its the app thats making your notebook hot.. u know, to save money..
good luck!
This problem sounds huge. I rarely run graphic intensive apps, but I may avoid such programs altogether now.
I have seen, on a few occasions, a garbled screen on my 2.2 MBP and I knew right away that it was the GPU. It is very similar to videocard failure on the PC from overclocking and/or heat issues.
And don't count on nVidia to be open with the details of this problem. Think MS and the xbox360. The company exists for the benefit of the shareholders, and they will quietly try to salvage their business without tell us exactly what to expect.
If failure rates increase with product age this could be a nasty time bomb...

I really cant believe that this could happen. I run my computer very hard (2.2GHz) in Bootcamp to the point that I have to stop because I can feel the heat coming off the computer. We probably wont hear anything until Monday though (4th of July!!).

Thanks for that..
It's still under warranty - only a couple of months old.
Do they take it away or send a replacement ? Can you get it fixed at an Apple store ?
I can't really be without it for a long time and I'm always dubious about 'repairs'....
well well, its finally out in the open. mac's are very much affected by this, please see:

or look for "NVChannel crash" with your favorite search engine. i suspected a serious hardware problem immediately and i've written several posts about it under the same name on apple discussions. good to see im so damn smart after all, bad to know i have a $2500 piece of junk in my hands with only a few months warranty left to figure out what to do now (santa rosa 2.4 mbp).
there's a skype public chat opened for some live problem handling strategy discussion:
http://www.skype.com/go/joinpublicc...UtTtuUpQDydpSr2bdfsKnfIG2t-e1ZXwczXLsL086rbbs
in conclusion: this is a crappy crappy situation to be in since frankly there are no really good alternatives to the MBP + OS X combination.

Nahh, My C2D MBP works great. But, it's also got an ATI card in it
Because ATI cards have less problems than Nvidia cards.

Why did Apple change to nVidia? I really favor either chip manufacturer. I think they both make awesome graphics. I really dont think Apple is going to change back over to ATI...but after this whole thing, they might.
So what temp does your current MBP run at in Idle and under load ?
Does it no longer get hot/warm at all now ?
Did your old one run at 65C under load or at idle ?
I'm not sure high operating temperature is a reliable indicator of a defective unit. Intel mobile processors are designed to operate at up to 100C. I don't now what the max operating temperature of GPUs are but it would probably be similar, especially seeing that Gigabyte sells a passively cooled desktop 8600GTS that runs at 99C under load.

Interesting..so by warm do you mean sat idling albeit with your iphone plugged in...
If so they are actually higher than mine at idle...
CPU A: 49C
GPU Diode: 52C
GPU Sink : 47C
HSink 1 : 46C
Hsink 2: 38C
Hsink 3: 40C
Wireless Mod : 37C
Memory : 40C
Enclosure : 31C
Disk : 36C
temps
From iStat Pro, during idling I get the following temps:
CPU 50
GPU diode 60-66
GPU heatsink 53-55
No audible fan activity
After playing Doom 3 for 10 minutes
CPU 60
GPU diode 78
GPU heatsink 60
Fans ramp up and stay on until GPU diode temp <70
So, are there any figures for "normal" or acceptable temperatures on the MBP?

Has then been addressed yet for Tiger users? I have had this annoying problem since day 1 on my 2.2 ghz MBP. I know it was fixed for Leopard a few months ago.
Hopefully after a few more people post some results we'll start to get a spread and maybe figure this out..
Interesting that your idle GPU diode is significantly hotter than mine and yet your sink is significantly cooler than mine under load - I don't know what that means...
I mean warmed up is the computer getting to its normal operating temps. Once I unplug my iPhone, my CPU temp at least should drop by 10 F.
Not for a long time. When the 8800's were first released they were a better value for money, despite being more expensive. ATI has been less expensive for a while, and have been a better value for money since the HD 3000 series. The 2600XT was also better than the 8600's if I remember correctly, causing them to do well in the midrange(though the midrange in general was quite poor game at the time).
Don't see how that has anything to do with Nvidia.
Anyway, hope they get this fixed soon.
Are you able to do a load test ?
We've now got two MBP's (inc mine) that are reading 78C under heavy load for about 10mins...
Computer was in sleep mode and I just come home, sent an email and looked at the thread. This MBP is 2 weeks old.
I'll post a stress image in a little while.
