coolermaster has a decent paste.the actual difference between pastes is only a few degrees in temp.durability (how long it lasts) is another story.ive had no problem with the coolermaster paste.unless you are overclocking paste is not really a big concern.now whether it is conductive or not is.you dont want a conductive paste to spill over on conductive paths on your motherboard.myself,i havent seen a conductive paste in quite some time.if you are heavy into overclocking i would recommend an aftermarket cooler and something like arctic silver high density paste.
