Yikes, no! I've lapped many a valve, and the valve grinding compound used (if that's what you meant, Sage?) is much too coarse (think 200-320 grit sandpaper).Sage wrote:... an old tin of car valve polishing grits might suffice?
For CPU/chipset cooling, I believe one wants as close to a mirror finish on the heat sink/carrier's metal surface as possible... a very fine automotive wheel/metal/aluminum polish like Simichrome, Flitz or Mother's would do the trick nicely, I'd think.
FWIW.
Although I'm perfectly happy with the performance of my old Pentium D equipped Dell box, yeah... they really put out the heat! (Nice for keeping toes warm on cold winter nights...). And they have no temp sensor built in, either... arrgh! Intel probably didn't want anyone to know just how hot they run.
