Is this a bit of overkill heatsinking? :P

hehehe can you say "too much thought into a simple question?" hehehe

Do leave it 1200 grit and don't polist though (if you were serious about polishing) reason being is 1) the arctic alumina won't hold it well polished 2) you get a bit more surface area if it's got scratces in it :)

P.S. Don't use arctic silver, it's conductive. Also I like the MK II thermal compound on the inside fet's and arctic alumina on the four corner fets. Sink stays on good, but you can get it off again later if you need to.
