Where to buy heatsinks/thermal paste/ etc...

[Neofate]

Well I am working on putting some passive and active cooling on my motherboard. Specifically a HS and fan on the south bridge, and some heatsinks on the mosfets. I just put a fan on the Northbridge. Man, the southbridge gets the hottest out of all of them! It will (almost) burn your finger if you leave it there a few seconds.

Anyways, back to the question:

Where can I go to get random sized heastsinks for low cost? The regular Walmart, Bestbuy, CompUSA (UGH!), etc doesn's sound like the right choice.

Would RadioShack have any heatsinks?

Also if I can't find the "exact" right type of heatsinks, what is the easiest/best way to cut them CHEAPLY?

If I have to buy a dremel, sigh, I guess I will, but if there is another way to reasonably cut the metal in a straight line then please tell.

Also, let me double check this.. Copper heatsinks beat all right? (Compared to aluminum, and god forbid, steel.) ?

Thanks a ton.

If there is a local computer shop go in there and aks if they have any old unused heatsinks, like old P3 ones or something.

Copper will be better than aluminium but for this sort of stuff aluminium is fine.

Check out 2cooltek.com. They have some alpha heat sinks that seem as if they will perform fairly well for your chipset and possibly mosfets as well. Kind of expensive $5 apiece

I cut the thermaltake Aluminium heatspreader into threes with a hacksaw. I also cut the copper base of a socket A cooler with a hacksaw. Initially for my 8500 memory, but I put a long strip on the MOSFETs and thermaltake heatspreakers ontop. I used a Black and Decker drill with a metal tool for wood work. The tool looks like the circular tube with knobs on found in some waste disposal units. The tool chipped away at the copper and gave it a straighter look and the dimentions to fit between the capacitors and wotnot on the mobo. It would have taken years to sand dawn with sand paper.
