have to ask, are you seeing that your paste has mushed out by lifting the heatsink after applying it?

the as5 squished out nicely for me - noticed after remounting the heatsink when i changed case layout.

your temps seem very high if you have lapped. im getting 25 celcius on idle @3.2ghz 1.4v ..... 44ish CPU load or 51 if in a game - extra heat contribution thanks to a large GPU heatsink next to the processor!!
