    Well, paste is the best to use. The best paste is Arctic Silver, and it performs very well and transfers alot of hest to the heatsink. However, some graphics cards use pads, as the distance from the core or memory chips is too large for paste to be effective. For that you will need to purchase those pads, but they are difficult to find.

    I have applied AS5 onto a pad. Got some results.

    CompUSA has Arctic Silver in-store if you don't want to buy online.

    I have used AS5 on my ATI x300 in may laptop on the core and memory banks with nice results. As other have stated you may want to be careful though because of the gap between the HS and chips. I have read online about someone actually using little strips of copper I believe it was to help fill the gap. Hope that helps.

    It was $10 for the 3.5g syringe, which is basically the same price newegg has it for (plus shipping).

    And yes, it is AS5.

    If you don't want to use AS5, you could always go with Ceramique, which has a much smaller break-in period.

    Ceramique is also a very good product, often returning better results for less money.

    From what I've read, AS5's 200 hour break in period means that's how long it takes for it's effects to be fully noticed as the product settles in. You can continue to use your notebook during this time.

    Yep I got AS5 from Comp USA. It cost me about $15 I think. I have noticed a little drop in temperature for basic usage.

    This is off topic, but your avatar is sweet! Do we really have a NBR FEAR combat clan?

    Technically you're supposed to cycle your computer during this period. I've never had a problem shutting off my notebook every night for a few weeks (usually its running 24/7), but I guess it might be a nuisance/problem for some people.

    Unfortunately, I've never used Ceramique so I can't comment on its impact.

    Just make sure you're applying it correctly, otherwise you'll get results opposite of what you're looking for.

    Well it is actually NoteBookRaiders clan but we all met on NBR - so that is why we left it in the name. Everyone is welcome.:D

    Sorry for the offtopic post.

    The thing is, all a pad or paste is made to do is facilitate thermal transfer from the chip to the heatsink. So if you add the two, it's better than just air, but it's worse than if you had used just one or the other.

    Don't ever mix pads and paste. Clean off one thoroughly before you apply the other. And put the paste on in a very thin layer, keep it as thin as you can while still allowing it to cover the entire chip.

    And the "200 hours" is how long the machine will need to be running before it's as thermally efficient as it'll get. You can use it immediately after applying the paste, but you won't see full effect of the paste until after 200 hours of running.
