Horrible Thermal Paste in Brand New MBP

From looking at your picture, it looks very similar to my CD and C2D MBP before I reapply the thermal paste with middle chipset being a bit less load than the CPU chip and GPU chip on the two side. There is a possibility of excessive thermal paste from the back (opposite to vent) where we can't really see until we disassemble the board.
Please can I ask a stupid question?
What are the three chips with thermal paste on, going from the edge of the logic board towards the middle?
CPU, North Bridge and GFX chip.
They're only the most important chips in your machine.. what did you think? Did you imagine lots of little rodents running around with a ticker-tape machine, and a fat cat being the dictator?
Please can I ask a stupid question?
What fits in the large space next to the DVI connector? I had always assumed that was the graphics card?
Apple installed two fans either side of the motherboard, or logic board, as they call it.. and they only spin in at 2000rpm on average. If you want your machine to take off, you need to bake it in a oven first - wait, it could almost do that by itself.
Yeah it sure looks messy and a 20 degrees difference is quite a lot as well. I remember the same discussion from the first revision MBPs; probably it's not feasible to apply proper thermal paste in the factory due to longer manufacturing times. I assume it's a tradeoff between short manufacture times and heat production.
So for the daring among us this action might help reduce the heat production. I used to use arctic silver for my desktop pc's; it contains 99.9% pure silver:
The problem with AC5 is that it'll start to curl after a little while, then it'll be less effective. And if you apply too much of the stuff, you have the problem of large lumps falling around in your mobile computer, which could cause another problem, since silver is conductive. On a stationary desktop system this is less of a problem, cause it's not moving.
What kind of chipset could Apple have used in SR MBP this time? It took me until I reapply the thermal paste to find out Apple indeed used 945GM instead of 945PM on my CD MBP which I'm less preferred as it generated a bit more heat due to higher TDP.
Under CPU-Z, is should show a string "965PM" or "965GM" chipset under motherboard tab. CPU-Z 1.40 supports 965 series chipset, so it is very strange both legit tools fail to detect Apple hardware! Probably the latest Bootcamp 1.3 driver disc doesn't contain the latest Intel chipset driver.
FYI, AC5 is not electrically conductive. It won't leak out either unless you use a spoon to put it on.
That would make sense. I don't know for sure, but I assume that conversions must be done to run PPC programs. Because of this it is also probably running a lot of instructions per second (realatively). If the memory it's using for the conversion from PPC language is not very large, it can do this very quickly. This means that your getting a very high instruction throughput on your processer. Essentially, it's putting more current through a wire. It's going to heat up more.
However, all of that is just theory and not based on a knowledge of what's going on.
Stop whining - it is to show detail to someone who ASKED for it. If you don't like it then stay out of this thread. Jeez.
There's no need to jump down my throat. The point is that the picture is gigantic and unfriendly to other forum users. You can't all of a sudden claim "stay out this thread, I'm using it to post my gigantic photos!"
At very least you could give an offsite link so it isn't throwing off the whole page and instantly slowing down people with less-than-speedy connections. And, for the record, the only real "detail" you can get from that photo is the watermark unless someone wanted to study the general placement of the chips on the board.
only 84°C..
Well.. if you hit 90-95°C your MBP will shut down.
I have motion rendering stuff on mine, both fans in full swing! And last week the summer heat (with room temp floating about 27-30°C) caused my system to exceed 93°C. Then it just shut-down, no sleep, no warning, no recovery. Just shut-down!!!
Lost loads of work.
So i've been reading up about all these heating problems with the new MBP's. I just bought one myself, and although i havent had the thing freeze or shut down on me due to overheating, i am still a little concerned.
So i decided to keep an eye on the temp of my cpu, during idle times, or even just web browsing with itunes going on. So at the moment i'm running at 52c, in a room that is about 25c. Doesnt seem TOO bad from some of the reports i've seen. So i started to play WoW in windowed mode, with the temp showing at the top of my screen in the menu bar. During WOW it seemed to stay around the 74c mark, but sometimes went to about 82c, but the fans were also in full effect, running about 5500 - 6000 rpm.
Can anybody tell me, with those numbers and temps, whether i should worry, or does it seem like mine will be ok?
My main concern is, sure, i could return this thing to the apple store and get another one, but what if the other one i get is the same way? I've just heard that so many people seem to be having problems, that it would almost be pointless to exchange it only to get another one that'll do the same thing.
edit: I've also heard some people report saying that these things can handle 100c, and i even read a .pdf by intel saying 125c. So, should we be worried?

As i've posted many times before, my 2.16Ghz C2D MBP goes form 50C at idle to 68C at full load playing wow and a bunch of other things open. Yesterday, while doign the very same thing, that is WoW, Itunes, MSN messenger, Safari, i hit 74C. Only for a couple of minutes.
Not Happy.
When i buy my AppleCare next week, i'm gonna go it into an apple licensed repair shop and ask the technician to repply the thermal paste under applecare.
The temperatures everyone are showing are mostly ridiculous for a laptop. The hardware can handle it but a laptop should not be running that hot. That defeats the whole bloody purpose.

Thanks for confirming. Not sure why Apple chose to go with higher TDP chipset on each generation of MBP!? The "GM" chipset with integrated graphics (GMA X3100) suppose to be used in upcoming SR MP. For SR MBP, Apple should use "PM" chipset since it selected the discrete GPU chip. In another word, the moment SR MBP gets power up, it uses more power to drive both built-in graphics chip as well as discrete GPU (Nvidia) chip. Apple could have SR MBP run much cooler and longer if it uses the proper chipset. This is how ThinkPad and other laptop manufactures achieved more than 6+ hours on real world battery test.
It just doesn't make sense Apple would do that, it is really a design issue. Seriously, we should inform Apple about it. Noneless, Apple could at least have better QC for thermal paste application to reduce some degree of heat.
As a financial contributor to this forum i'd prefer my money not to be wasted on bandwidth for huge pictures like that where he/she should have displayed a thumb to a bigger picture stored elsewhere
There is nothing wrong with those temps! Mine hits 90 but i'm not crying about it! the chips are designed to run upto 100C so its fine. if your that bothered get an iLap. Mine came today and it knocks 10C off my temps.
Moan moan moan..
Sorry your poor 900baud modem can't take the strain
I posted those photos cause someone asked for details. I'll try not to make a habit of it. They are hosted else where, but you can't access hi-res photos there, i'm posted restrictions hence it's posted here. Plus, on a pro account, there are no restrictions in regards to bandwidth usage, be thankful it's only one or two, and not hundreds of them...
