What metal of heat sink?

I have MacBook Pro 2010. I want to replace the thermal compound in it.

Can I use liquid metal like Coollaboratory Liquid Pro???

Does the heat sink have aluminium metal??

Update (12/19/2015)

Ok, guys. Thermal compound(that I want to use) from Coollaboratory consist full of liquid metal.

But my question is WHAT METAL OF HEAT SINK?

Here's it:

You can see 3 colors: black, yellow and grey.

WHAT IS GREY METAL? Nickel, iron, aluminium... or what?

Please give answer if you really know it.

Update (12/23/2015)

Today I have replaced a thermal compound. I use liquid metal thermal interface. I wore it carefully only on yellow heat sink details that contact with chips and directly on chips.

Also I blow from my laptop a lot of dust! (for a 5 years!) :)

Now temperature in standby/light browsing is 40-45 degrees C.

Is this a good question?

First you may want to review this table: Thermal Properties of Metals, Conductivity, Thermal Expansion, Specific Heat.

Liquid Metal thermal paste is corrosive which is why you can't use it with anything that has aluminum. Many of the MacBook thermal masses mounted to the chips are aluminum alloy. The heat tube on most appears to be copper which is filled with a liquid on many.

Frankly, I'm with Mayer here stick with a Silver based thermal paste like Artic Silver and call it a day. Don't over do it and make sure you don't have any voids.

Update (12/18/2015)

Aluminum alloy - Black is an epoxy coating that is put on top of the the entire heatsink unit. The thermal mass may have some Yellow anticorrosive coating showing just at the coating spray seam. The exposed metal is an Aluminum alloy on the heat sink mass that touches the chip. The fan fin section is also an Aluminum alloy. Aluminum is one of the higher thermal transmissive materials (Silver, Copper & Aluminum being the top three).

No. It won't transfer heat properly and it will destroy your processors as they will not be able to expand and contract correctly

. Use the correct thermal paste: Arctic Silver Thermal Paste

Why? What is the reason?

I've read many tests of thermal greases and Coollaboratory Liquid Pro have the best results everywhere!


petyandr post a link to this "Liquid Metal" so we can see how compatible this will be. The next best thing, if it is such great stuff, would be for you to try it out. Let us know how well it works.


While your at it run some axle grease in your car engine and let us know how that woks too.


OK, that is not liquid metal. That is a thermal compound. You need to be more specific when asking a question like this.
