I purchased an AMD 1 ghz cpu and it came with a HS to my suprise... (i ordered a global win fop32) ... Anywho! it has some crap white thermal paste, and some artic silver paste should be coming in the mail soon. Should i remove the thermal paste that is on the heatsink rite now? How much of a difference will the artic silver paste make ? And most importantly how do i properly remove thermal paste from a heatsink???
