Difference in Artic Silver and Alumina adhesive?

[Vince604]

Okay I might get a chipset cooler but I can't figure out what's the difference between Artic Silver Thermal Adhesive and Artic Alumina Thermal Adhesive?

Or would thermal tape have better thermal transfer and be better than the two?

 

[CharlesHF]

No, thermal tape would be worse than both.
<A HREF="http://www.arcticsilver.com/arctic_silver_thermal_adhesive.htm" target="_new">Arctic Silver Thermal Adhesive</A> is made from silver particles. It is generally considered to be better.
<A HREF="http://www.arcticsilver.com/arctic_alumina_thermal_adhesive.htm" target="_new">Arctic Alumina Thermal Adhesive</A>is made from ceramic particles. It is the lesser of the two, but it still good. Good luck!

Okay so the best Thermal adhesive on the market is Artic Silver Thermal Adhesive?

You got it!

Okay thanks!
So would you know if aluminum heatsinks are better or copper?

There's not going to be a fan but just a small heatsink itself to be put on a chipset.

 

[CharlesHF]

Copper is much better at conducting heat than aluminum is; go with copper if you can get it.

That's true but I thought copper only has better heat conduction but heat escapes from aluminum faster?

For heatsink info you should read this:

It's like the heatsink bible

Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway

 

[CharlesHF]

Notice that he is not actually trying to cool his chip, he's trying to cool his chipset.

Since copper conducts heat better than aluminum, that means that it loses it faster, also. Better conduction=better heat flow through the metal.

Alright then. Thanks for the site.
Would the size matter too? Like if it was thicker or wider?

When money is no object and I want the best, I use epoxy mixed with microfine diamond or beryllium powder (the latter is toxic). But since money is always an object, I instead use ordinary silicone rubber sealer, a much underappreciated thermal conductor.

Lol. I always wondered what it would be like for someone to make a heatsink out of diamonds. Diamonds are very dense and dissipate heat fairly well. Now, not as good as copper, but still it would be 'interesting.'
