I am building a new system. I am using a Kt-7 mobo with a 1.2ghz AMD Duron on it. I have a huge HSF on it. Pic is here...

So is thermal paste neccesary? In all cases? I have heard that durons run pretty hot. I have also heard Artic Silver is the best. If needed, were can I get it? I use paypal to pay, so that would help if they accept it. Thanks for the help.
 
Most definilty YES, thermal paste is needed. AS5 seems to be the popular one of choice (I don't use it personally, I just left the little intel heat pad thing on there)

oh yea, and www.newegg.com
 
as to if it's NECESSARY, I would say, no, as most heatsinks will come with a thermal pad on it. This thermal pad, does an adequate job of cooling for most normal usage. Now, if you plan on reusing your current heatsink, you must scrape off any remaining residue from the thermal pad/paste, and reapply a fresh amount.

Now, for overclocking, or for best performance, it's always recommended to go with a quality thermal paste, like Artic Silver, or a similar product. Most computer shops carry it, or like I went to Best Buy and got a generic version of Artic Silver...it does the job, and the tube you get will last for several HSF installations.

newegg sells thermal paste I know, any online computer store should have it, eBay, etc.
 
Thermal paste is definitely needed for your AMD chip. You need some type of thermal paste between your chip and heatsink for effective heat transfer.

Check out SVC, they have decent prices for AS paste.
 
well, I'd say it isn't necessary if you have 2 PERFECTLY flat surfaces... and when I say perfect, I meant it.

If you don't have 2 perfectly flat surfaces (both probably have to have CMP done on them), then you probably should put some sort of thermal interface material. On a cool running chip, the effects might not be noticed as much, but better safe than sorry.

Thermal interface material will help facilitate the transfer of heat from one surface to the other. A superior material will make the process more efficient. Right now the best materials are AS5 or shin-etsu. These use micronized silver particles (or at least AS5 does, not too sure about shin-etsu). We will probably see better results as nanoparticles of silver, or maybe copper, are introduced to formulations.

Anyways, my point is, you probably should have some sort of material in between the core and the heatsink. If its an emergency, leave some toothpaste on there while you run to the store. Just do it before it dries up...
 
Instead of paying 3 bucks for a tube and shiping costs, a local store might have a packet laying around.
