I have several epoxies, but what one do I use? Ive never worked with it before. Im guessing I want the quickset Plastic metal glass concrete epoxy right? AND its a good heat conducter?
 
Well, what are you sticking to what?
Kindof need to know that in order to help you select the right one.

And as for heat conducting, most epoxy's are polyester resins, and make poor heat conductors. Like using a piece of your dad's old jumpsuit from the 70's to make a TIM patch. :p

If this is for your PC and you need an adhesive with good thermal properties, go with Arctic Silver
 
Hi, I'm probably open up a can of works here, but I'm curious to know the best way and product to thermal transfer from the CPU to the cooler. I am using a Rackspur. (a total copper bottom, pretty looking) 80mm fan too !! I have always bought factory cooling and never had to worry about applying thermal grease. How do you do it !!??
Thanks,
