However, drops in temperature, however, were not night vs. day difference, only very sight decreases by <2-4 degrees C, if any.
@nikhsub1, nice work. I agreed with reapplying the thermal paste. I did it on my previous CD MBP, it drops about 18C (on idle) 15C (on load) immediately after using AS5 thermal paste.
Just curious if you had chance to note down the NB marking? Was it 965PM (8W) or 965GM (13.5W) ? If it is latter, the TDP is much higher than 965PM which consequently produced much higher heat even after reapplying the thermal paste. You may also read the chipset info from Intel Chipset Tool or CPU-Z (under motherboard tab).
A. The point of thermal paste is to help conduct heat between the chip and the heatpipe/heatsink/etc. The chips are not lapped, and contain many grooves and microscopic holes. AS5 specifically contains different size particles that fit in the grooves/holes and help conduct heat. That is the reason you don't want to much is that the main purpose isn't to act as a layer between the two surfaces, more like create a lapped-like environment.
B. My question is, whoever has replaced the thermal paste, when replacing the heatpipe or whatever goes over the chips, when re-lifting it up, does the thermal paste make contact with it? Maybe apple uses so much because there is a gap between the chip and heatpipe. In that case, you should buy some copper plating 1.5mm thick or w/e seems applicable. clean the plate with some soldering paste or something acidic. put some as5 on each side of the plate, then put in place, and re-assemble. Copper is one of the best conductors of heat.
C. I'm guessing the gobs of thermal paste is to cut costs. I'm not sure if robots or a person assembles macbooks, but either way to apply the precise amount of thermal paste in a razor thin layer would take more time than just put a glob on it. More time=higher costs.
I would fire the apple engineer who designed a gap between the heatpipe and the chips. As a matter of fact, I don't think he should be an engineer period.
In my opinion, form looking at several different cases on the internet, the application of such a huge amount of thermal paste has no gain other then guaranteeing that the entire contact surface between the chip and the heatpipe has some paste no matter how bad the assembly was.
It's been confirmed SR MBP used GM965 instead of PM965. It's strange Apple would do that since PM is meant for professional laptop that uses discrete GPU like the one you mentioned. GM (w/integrated GPU) chipset is meant for MB with limited size logic board form factor. Perhaps Apple is trying to save cost by ordering large quantity of GM chipset which can be used both in MB and MBP. The draw back on MBP is the excessive heat generated due to higher TDP of the chipset when pairing with additional GPU.why would it be the GM? its already got a graphics chip.... G84/86 (which ever one the 8600 is)

Hmm, I can't spot the GM marking there. I suck. Where is it? Could you circle it in photoshop?
I called Applecare about my overheating notebook/laptop. They are apparently going to replace the fan system - kinda odd.
Does the logic board need to be removed to access the fans? Or can the fans be replaced independently?
Considering they are attached to the heat sink I would imagine the logic board needs to be removed, but I am not sure.
Are you referring to the latest 17" Macbook Pro?
hello all
after reading most of my post, I'm very concerned of my soon-arrived SR MBP. Should I gather all the pictures you guys linked/attached, and print it out, send it to the apple's repairshop after I received my system, and ask if they should reapply the thermal paste correctly?
Opening and checking out the motherboard/logic board of the MBP seems....scary and hard.
Thanks!
probably done by a human, assembler or something like that...
Sorry not a PS expert here. However, by extracting the chipset image from UltraNEO*, you can see:Hmm, I can't spot the GM marking there. I suck. Where is it? Could you circle it in photoshop?
Even though it may be an overaction, I'm glad threads like these are around. It keeps apple on their toes and the product quality high.
