Currently Being ModeratedJun 13, 2007 11:59 AM (in response to bcbarnes)Oh dear, after receiving my system (June 6th), I just had to have a sneak peak at the handy work, just to conform are the rumours true!
On dismantling the system, after removing just about every visiable screws, I was able to take apart the entire system.. I was presented with a MBP with way too much Yellow sticky tape. It's on everything!!! On removing the logic board I discovered there's enough thermal gunk for about five additional systems!! Apparently this is Apple's idea of using Thermal Paste..
Modified with and replaced with high performance thermal paint... no more harboring excessive heat back on to the chips.

Currently Being ModeratedJun 13, 2007 2:58 PM (in response to TheFishyFew)Just wanted to follow up that I did run the Disk Utility first and repaired some permissions. That did the trick and my Mac is up and running again. As my computer is all of 3 days old, I will take it in to the Apple Store on the weekend and see if it they can make any conclusions regarding the kernel panics.MBP 17" 2.4 Ghz, Mac OS X (10.4.9)
Currently Being ModeratedJun 13, 2007 3:42 PM (in response to Eric Jefferson)Hi there,
Well, my stock system used to idle around 45-54°C, for a system that's not doing much other then surfing the web; that's pretty hot >< and that's without the SMCfanControl software running.
Currently, it's kinda idle, with photoshop running in the background.., the temp is floating around 38-44°C mark. For experimental purpose the fans are still on the lowest setting (about 1998-2003RPM).
I'd would say there's definitely some improvement, though under heavy load it does peak around 60-65°C, which is a load more healthy than the average 78-90°C that other people seems to be getting. Setting the SMC software to 2200-3000RPM seems to keep the system much cooler, even under load, but I assume one would be sacrificing battery life for a cooler mac. Personally, I'd like my machine enjoy a longer life!
I wonder, how many people would take maters into their own hands, and modify their machines, knowing they're voiding the warranty. Would you mod your machine?MacBookPro (glossy), Mac OS X (10.4.9), 2.2Ghz/4Gb/160Gb @ 7200rpm (hey!! still need more space!!)
Currently Being ModeratedJun 14, 2007 9:25 AM (in response to UltraNEO*)Wow! This is incredible! You see, this is the kind of important first-hand report which is extremely informative.
In their rush to assemble and ship as many SR MBPs as possible, the old THERMAL PASTE problem is back. Sloppy application! High temperatures! Total crap.
This is the same old problem. When will it ever be fixed? This lessens the reliability of the system!
If anyone else opens up their SR MBP and inspects it, please report back. Importantly, include your CPU temp under full load before any modifications to your system. Thanks!
Currently Being ModeratedJun 14, 2007 11:49 AM (in response to bcbarnes)This is appalling, I've had such a horrible experience with these laptops, i had to exchange/replace my second Gen. MBP 7 times or so to have stable, quiet, intact machine, I'm going for replacement number two in this third Gen. MBP 2.2 stock, these thermal paste pictures make me want to vomit, I've been phoned by one of his steveness'es assistants arranging that i meet with a genius on my next exchange and check everything before i leave with the new unit. Those pictures scare me. I don't understand why these machines are made so carelessly. Help me out I,m debating if i should accept the replacement or get a refund, ill never be able to know if the thermal paste was applied correctly, unless i bring it in again for service. this *****. i need comforting.Macbook Pro 15" 2.2 ghz 2GB RAM 128 Vid card 120 Gb Hdd, Mac OS X (10.4.9)
Currently Being ModeratedJun 15, 2007 11:06 AM (in response to horatius)The CPUs go into a restricted-operating (shutdown) mode when they get too hot. Anything NEAR that temperature is way too hot. I've built dozens of desktop machines and used many laptops, and NEVER have I had a CPU temperature over 85C. Under any sort of load. A properly assembled machine simply will not run that hot. I believe this has been clearly demonstrated by the thermal paste pictures and comments elsewhere in this thread.
Currently Being ModeratedJun 15, 2007 12:12 PM (in response to bcbarnes)I am not a technician only a customer so I'm talking by my experiences with Mac , right now I have also a black Macbook and it runs very hot(internally) althought not like the MBP(externally), anyway it's hard to belive that after a lot of problems , forums pictures showing clearly the thermal past wrongly used and a lot too MBP returned ,this people(Apple) did not fixed it?.They can't?
I thought this machines were well made and for the price it should be ,no?MBP W8615, Mac OS X (10.4.8), mac mini ,powerbook g4,ipod video 30gb,Macbook Black
Currently Being ModeratedJun 15, 2007 1:00 PM (in response to horatius)I guess maybe I was a bit harsh sounding, because I care passionately about this issue. It's quite possible that even if they run hot, the MB/MBP will work ok in daily use (until it prematurely fails). While they may have corrected this issue in the past, it looks like with the manufacture of the new SR MBPs, the problem has come back in at least some significant fraction (if not all or almost all) of the new machines being shipped. Hopefully soon this will be fixed, for good.
Currently Being ModeratedJun 15, 2007 2:02 PM (in response to bcbarnes)The harsh point is the temperature matter not yours do not worry.
I care too because I became a fanatic of Mac , and I do not like to fry my leggs??
Anyway we should push Apple trought this forums to do the things properly.
Belive me they will read this comments.MBP W8615, Mac OS X (10.4.8), mac mini ,powerbook g4,ipod video 30gb,Macbook Black
Currently Being ModeratedJun 17, 2007 11:54 AM (in response to horatius)Well, Intel says the CPU will operate up to 100°C and more, but in actual fact, the hotter your CPU becomes, the short it's life span will become. Since the processor is the heart of the machine, I think it's wise to take care of it.
For example, we all know our hearts keeps us alive and we know too much salt is bad... right? So we as healthy humans reduce our salt intake to prolong our life... if that's true, why shouldn't we try to reduce the heat in our Macs? I think it's a wise move.
I actually returned my first MBP to apple, as there were some odd problems with the left USB port but I didn't mentioned anything about the internal modifications, the store was happy to do a non-quarrel exchange, like for like.
On dismantling my replacement system I was more shocked, as there were even more thermal compound smothering the chips than on the last system. Here's more photos:

- it's gonna get hot!!! Will they come off? :
This last photo is truly unbelievable!
Apple has actually attached/stuck the thermal heat sensors to the case with nothing more then some sticky tape...
and we all know what happens when the glue gets hot!!!MacBook Pro (SR), Mac OS X (10.4.9), Glossy/2.2Ghz/4Gb/160Gb @ 7200rpm (hey!! still need more space!!)
Currently Being ModeratedJun 17, 2007 1:10 PM (in response to UltraNEO*)So what is the operating temperature for these chips. I think someone said intel rated them at 100C if that is the case what is all the fuss about. Are we assuming that lower is better? With each new generation of chips sometimes the old notions change. I my self would like to see some documentation that these computers are out of speck before we slam a manufacturer.G5 Dual Core 2.3, Mac OS X (10.4), Macbook Pro 2.4
Currently Being ModeratedJun 17, 2007 1:16 PM (in response to bcbarnes)I returned my Sr MBP for a new one. I haven't gotten my new one yet. I used iStat and I remember my CPU being around 83-84 C. Both fans stayed at 1996 rpms to 2000 rpms. No one has confirmed what has happened to my laptop. I suspect it could have overheated but, It was kept on my desk on a Targus Chill Mat all the time. It is probably something simple like the Core Duo macbooks and the firmware needs to be adjusted.MacBook Pro, 2.4 Ghz Core 2 Duo, 2 Gb of Ram, 256 Mb GeForce GT 8600, Mac OS X (10.4.9), New To Mac
