I am not going to use ic diamond again, it left quite ugly pits in both the cpu and heatsink (both lapped). So after taking it off I had to lap them both again, could be because copper is quite soft and diamonds are ... well ... hard as diamonds. I don't understand the 44 tim round up, metalpad should, if applied correctly, perform on par with liquid pro. I just put in on my gpu, will report back with temps
