Re-applied the thermal paste on my MacBook Pro... AMAZING results!

A little bit of physics
Got my 2.2 MBP this week, and installed iStat. What seems really strange to me is that the GPU diode(66C) and the GPU heatsink(51C) temperatures difference is 15C. The only possible reason i see is the bad thermal paste connection between those. On the other hand, the CPU and CPU heatsink temperatures are the same - 52-53C.
I believe that GPU should produce a lot of heat, but these numbers seem to be abnormal.
Comments are appreciated.

I've always wondered the same thing. Right now my GPU heatsink says 45c and the GPU diode says 59c
At the moment my GPU heatsink is about 48°C, the GPU itself 44°C. Mind that these temperature readings aren't very accurate. In my case, most likely the heatsink read-out is slightly too high and the GPU readout is slightly too low...
When I run something graphics intensive (like a game), the GPU temp is significantly higher than the heatsink temp, which is pretty normal. But if your GPU temp is much higher than the heatsink even when your Mac is completely idle, maybe the thermal connection between the GPU and the heatsink isn't optimal...
Thats odd..I sorta have the same thing. Here are my current temps. I do think however that the thermal paste has gotten better because my temps are much cooler than my MB. My MB would be at about 140-150 all the time.

I have posted this a few times and no one replies, so I am hoping to get a heads up this time. I like my MBP and have no problem pulling it apart, but I am worried about going to the level that it requires to reapply the thermal paste. Is there a company out there that will reapply the paste? I would gladly pay to have it done or even certain mac individuals that will do it? Thanks in advance.
No. I wouldn't arbitrarily open your MBP just to 'see'. I knew than mine was an issue, I mean, 60c temps while surfing is a bit much. You can post your temps and we can see if they are out of the ordinary or not. I have read a lot of reports of users replacing the thermal paste and seeing zero difference, keep that in mind too.
Here are my temps. Only thing running right now is Mail iCal, and Safari. The temps are with a USB cooler under it on some beefed up rubber pads to hold it about 1/4 inch away from the cooler.
I was doing a movie in Handbrake one day and the MBP actually shut down on me cause it got too hot. That really aggravated me.

Can you show me that in Celsius? The machine should never shutdown due to heat, if it does that is a huge problem and I would take it back to Apple.
FYI: pasting the right way
Hi
Just thought that I'd share this because most ppl #include <mysel.f> don't generally read instructions

How did you remove all that thermal paste??
I didn't. but if you want to ... use this according to this <pdf>

That's even lower than my temperatures, and CPU load is pretty much zero here. But my MBP has never shut down automatically, not even while playing games that make all fans run at full throttle...
I'm going to try to redo the movie again today and see if it happens again. I was using Carbon Copy Cloner yesterday and it shut down again, so I started over and watched my CPU processes and noticed that Norton Auto protect was taking all of my CPU juice and not allowing anything else to work. I took auto protect off so I will see if that changes anything.
I am 100% positive that the CPU and GPU are soldered to the board. The only mac that didnt have the CPU soldered was the Mac Mini Core Solo.
I'm replacing the bottom casing of my MBP when the new casing arrives. Do you think it's worth applying my own thermal paste when it comes to rebuilding the MBP into the new case?
Are the chips easy to get to? I'll order some Arctic Silver thermal paste ready for the job
Still a no go. Tried to burn the movie again and the temps shot up to over 200F (94C). That is pretty close to the shut down range, so I just shut the program down. Oh well.
WOW!! 94C. Thats super hot. Are your fans running? i'm running handbrake for about 2 hours now (converting my family guy seasons) and the highest i've got it to is 70C. But I use smcfancontrol to crank up the fans to 5000RPMs. hehe.-JoE
No. You have to completely remove the motherboard from the machine... the chips are on the bottom side of the board.Are the chips easy to get to? I'll order some Arctic Silver thermal paste ready for the job
Seems to me you have a fan issue as opposed to a paste issue. The fans should kick on HIGH at about 80C or so and stay that way. Do your fans do this?
I was using HB to burn The Kingdom. I have used it before with no problems. My fan control only allows me to crank up to 3500 rpm. Will look for an update.
Found a good link for the SMC update - was running an older version. Even under latest version with 6000 rpm running the MBP still shut down cause of too much heat. HB will burn other movies no problem, but for some reason The Kingdom causes it to overheat and shut down.
