can anyone tell me for sure the thickness of the heat sink thermal pads? the one i looked at briefly appeared to be .5mm, but i'd like to be sure before i order more. i already have some on the way for my gpu, which also has torn pads i saw when re-applying paste so i should have some extra .5 and 1mm. thanks for any help. also, i just got this board to build a "new" system while i wait on a decent deal for a 12th gen for my 690. so, if anyone has anything else i should check, any maintenance i should do, greatly appreciated. new to building, so don't know exactly what all i really can do. but i'm mechanically inclined, intelligent and pick things up quickly. thanks.
