Hi I'm about to order all the parts for my computer and I'm wondering what the best way of applying thermal compound is? Should I use TX-3 or AS5? Thick or thin?

Right now all I know is the best compounds are TX3 and AS5, and that you need to get a good spread.

Any help/experiences/advice would be much appreciated.

Thanks

Just put as thin a layer as you can on the parts. If it is to thick it could act like an insulator in stead of thermo compound.

I have used AS5 for a while and it works well. I have not used TX-3 so I can’t comment. I will say that I was looking into different thermal compounds about a month ago and found a good review on a large group of them. I can’t remember where the article is, but I remember the OCZ freeze was rated very well. It was place will a bunch of higher priced compounds and it cost about the same as AS5.

As for thickness, you want it as thin as possible with it still covering the whole surface. If you use OCZ freeze I have heard that it is a little thick and do not try to spread it, use the pressure of the heat sink.
