thanks for the advice. I was planning on testing which ever unit i get (haven't decided which one yet) on my foxconn bloodrage first since its expendable and my classifieds are not. I live in switzerland and to be honest i have no idea what kind of humidity level we have here, id guess medium. I think ill have to be brave and try it without and if there is too much condensation ill use grease. I take it there is no way to clean out the grease in a cpu socket if i ever needed to RMA one?
