I have had to send back my motherboard and have just recieved a replacement. when i reinstall the processor do i need to scrape off the original thermal interface, which was already on the heatsink (AMD athlon 939 venice 3500), and add new paste or can i just reattach the heatsink with the original paste?
If i do need to add new thermal compound does it matter about the quality? how much should I spend?
probably best to reapply as they've been separated, I'd suggest isopropyl alcohol on a qtip to shift it from the cpu
arctic silver is supposed to be one of the best heat transfer compounds, but any is better than none
I always use ArcticSilver paste and ArcticClean (http://www.arcticsilver.com/)....More expensive, but Worth it.:thumbsup:
I dont even take the old compound off, i just put a blob of new stuff on without issues..
As long as you have a good equal thin layer to mate with the Cpu you will be ok . You only really need to go to the extremes if your gonna overclock in my experience . But thin and level is best as a rough guide .

And if you do use arctic silver, be veeeeeerrrry careful when applying it. If it accidentally touches something it shouldn't it *can* cause issues.... being basically a superconductor.
But it's rare, and I'd recommend it!
A room temperature superconductor, get it patented quick.
*runs to patent office*
Yes, well. I've known of a few people who accidentally got some on the mobo/bridge connectors (muppets) and when they turned it on, some connections got made that really shouldn't have and, well...
you mean it's an electrical conductor then not a superconductor ;)
Yeah, that would just be a conductor, like most metal. (Artic silver contains silver, hence the name).
If it were a superconductor it would have revolutionised power generation and distribution, amongst other things.
