I got this big 80mm Heatsink from Alpha. FH8040. [img="http://www.micforg.co.jp/images/c_fh.jpg"] [url="http://www.micforg.co.jp/c_fhe.html"]Specs on HS FH8040[/url] I also have some 1/8" copper plating that I want to fix to the bottom of the HS. Reckon I will use AS epoxy to join the aluminum and copper. Problem is that I live in a 3rd World Country (Hawaii) and am having a heck of a time finding someone to cut the base of the heatsink from 7mm (1/4" approx) thick to 3.5 mm (1/8" approx) thick. The only place I can find that is willing to do it wants to charge me $125! YIKES. Anyways, if I just epoxy the copper plate to the HS as it sits, the base will be approx 10 mm (3/8" approx) thick. Is this too thick for the base? Also where i join the copper and aluminum, should I lap these surfaces really good or leave them unlapped? I figure if I leave them kinda rough, the epoxy will grip better. On the other hand, if the surfaces are smooth then the heat should theoretically transfer better. Or does anyone know of a place online that I can send the HS to get it cut? Any other input would be most appreciated. P.S. Gonna use a 68cfm 80mm Delta fan. Probably will have the air blowing upward since this HS came with a skirt. Mahalo nui`i.
