Which is the best non-electrically conductive thermal compound?

[Subterranean]

I need a good thermal compound, but for the application I am using it in it must be non-electrically conductive, but with the best heat transfer possible. Ive narrowed it down to 2 so far:

Arctic Silver Ceramique
Arctic Cooling MX-2

Are there any better ones? Otherwise, will I see much of a difference between these two? Although the MX-2 is always more expensive, you do get almost twice as much with it so I can't go by price alone.

Also, do these compounds set solid, almost glueing the items down, or do they stay somewhat liquid?

Thanks for any help.

MX-2

MX-2 overtaken AS5 now then?

I thought Tuniqs new one was better?

This is an epoxy so it will be sticky and will harden

Heh, i guess I'll go with the MX-2 thanks to the advice here.

MX-2 is better than MX-1, and MX-1 has been ahead of AS5 for a very long time...

Also, AS5 is conductive, so that's out fo the question already

I wonder how many people didnt read the caution first before applying

So why for the last few years have people been saying AS5?

I have two tubes of the stuff ffs lol

I've been saying MX-1 for years, and the test's have shown MX-1 to be better for years...

People are so used to using arctic silver when it was first about (and then it was the muts nuts) that they just stuck with tradition, a lot of people will still say AS5 over MX-2. At the end of the day, they are both good compounds, and chances are, the application of the stuff will ultimately have more effect on your temperatures.
