The arctic silver doc explains that one needs to apply some to the hsf, then remove it with alcohol/nail polish remover, is this necessary if the hsf is brand new
Yes...because who knows what might be on those HSF's. Man...anytime your dealing with not only expensive but sensitive materials like the cpu...it's always good to make extra precautions. When i got my swiftech-462a out of the box...i cleaned it off...applied the artic silver on it...so the silver could get into the grooves of the copper base. Then i applied a paper thin layer on the cpu, then wiped off the artic silver on HSF..and put it on. Time consuming but better safe then sorry. Also, i heard copper is one of the dirtiest metals around...when i cleaned mine brand new...all this bronze gunk came off...lol. Make sure you use a lint free type of fabric when cleaning it! (something like one of those eye glasses cleaners)
