Radiowavers Level 1 Level 1
My friend has bought a new Macbook Pro, in England.
He has started to have problems with overheating.
Both I and him live in Russia, where no Apple stores are situated,
and we are not going to visit Europe anytime soon (before the 1-year warranty expires)

So, I am going to fix it myself, because I am quite skilled at this field.
I am going to replace the standard Apple thermal grease.

I have a Coollaboratory Liquid Ultra, one of the best thermal interfaces available:
The only problem is that it is prohibited to use it if the part of the cooling system
which comes in a direct contact with thermal interface and CPU/GPU
is made of aluminum.

So, please, tell me, what the part of the cooling system,
which comes in a direct contact with thermal interface and CPU/GPU,
is made of?

Macbook Pro (Early 2011), Mac OS X (10.6.6)

    I have no definite answer to your question, and I suspect that Apple has not published and will not publish any information that answers it. But I think the likelihood is very high that all the heat sinks in the MBP are aluminum, because aluminum is light in weight and a very efficient conductor of heat, and Apple is clearly very comfortable working with it. So you may want to find a different thermal paste to use.

    Strange, but the other guy said the opposite
    (he thinks they are made of copper - because of specific color).
    He has also provided some photos, and said that it's a proof:

    Now I believe him that CPU's and GPU's heat sinks are made of copper,
    but I still don't know about the third heat sink (for Thunderbolt controller):

    What model computer do you have??
  • Radiowavers Level 1 Level 1
    MC723 (MBP early 2011 high end 15")
    But it's probably doesn't matter - high end 15" or 17".
    Their hardware is nearly the same.

    The problem is that I don't know what is the material for third heat sink.

    I have no idea what "other guy" you're talking about, but the pads pictured in your photo do appear to have copper surfaces. If they were aluminum, there would certainly be no reason to make them look like copper. So the "other guy" is probably right.

    I also suspect that if two of them have copper surfaces, the third one probably does too. But if you're tearing the MBP apart yourself, you'll soon find out for yourself.

    I think that your idea of tearing apart a new MBP to replace the thermal paste is a stupid idea. Don't you think that Apple has used the most efficient paste to begin with? I really don't think they are in the habit of using inferior materials, and think that any attempt to replace them is going to leave your friend in exactly the same situation except without a warranty.

    My suggestion to you would be to call Apple and possibly ship the unit back to them. If that isn't an option, look for a utility that will allow you to change the efficiency of the fan behaviour (can't recall the name of it but I'm sure someone will chime in)

    Andrew: I agree in principle that it's a bad idea to void the warranty on a brand new machine by tearing into it and replacing the thermal paste. But these guys are in Russia, where by every account I've seen, getting a Mac serviced competently is impossible. Their first mistake was in buying a Mac at all, and their second was buying it in Britain so they don't have the option of returning it. They know the warranty on it is useless to them.

    While I admire your classic Russian do-it-yourself attitude,
    you will certainly void your worldwide warranty.
    Remember, even though there are no Apple stores in Russia,
    your can mail your computer to Apple for warranty service.

    If you do decide to risk it all, you might consider Arctic Silver 5:
    It doesn't seem to have the problem with aluminum.

    Here's an interesting article where a user was able to reduce temperatures by 30°C!

    I understand that they are in Russia, but certainly they could ship it to Apple? And even if they had no warranty option, I am 99.9% sure that thermal paste isn't going to solve anything. I haven't seen any other complaints here and they all have the same factory thermal paste, so that would be the last thing I would look at. First off, have we even deduced that there is an issue? Has he checked the CPU temperature to see if its within the guidelines? Is it shutting down due to heat? Are the fans blazing? The answer to all is "we don't know", so to be advising this guy what thermal paste to use borders on insanity.

    My understanding, based on previous posts, is that Apple has no corporate presence in Russia. All sales and service are through licensees, and they are incompetent, unable to get parts from Apple through Russia's corrupt import system on anything approaching a timely basis, and often dishonest. If half the stories are true, anyone using a Mac in Russia is better off entirely on his own than trying to deal with Apple's licensees there. As in most other countries, a MBP owner in Russia needs to have his machine serviced by Apple's licensee there, or Apple won't cover the service under warranty. Perhaps our Russian friend could send his machine to an associate in Britain or some other country to take it in for service, but I suspect it couldn't be shipped back to Russia without a major hassle and perhaps a major cost.

    In any event, the OP has described himself as "quite skilled," and while it doesn't hurt to take such descriptions with a grain of salt, I'm not sure we can assume he has failed to think this through. He's in a tough spot if the machine really is overheating, and iFixit has expressed amazement and dismay at the excessive amount of thermal paste they found in dismantling one of the new MBPs. So what the OP proposes is certainly something I'd never do myself, but if it's what he feels is necessary, I'm not averse to trying to be helpful.
