same here, no difference after my lap.

i've had bad results after lapping too. saw a temperature increase but it was because i didnt mount it properly. upon removing the heatsink i saw the paste had spread unevenly to one side. re-applied properly i saw excellent results.

the as5 spread out fine for me. after putting half the recommended thermal paste on arctic silvers website, i positioned the heatsink on top, pressed down firmly with a fair amount of pressure rotating just a few degrees 2 or 3 times. not wanting it to pop up and allow air in, i kept the pressure on the top of the heatsink and screwed it in place.

oh and if you want the best chances / ability to mount it properly, remove the board from the case, its small compromise

Lapping had close to 0 difference for me on idle. But for load temps, my 4 cores were all within the same range as the other (check above post).

Question: So when I lapp my CPU, does it make sense to lapp the heatsink as well?

Definitely, except if your heatsink is already flat and the surface has no scratch.

[it_burns_when_i_pee]

even if its flat a smoother surface has lets pits and valleys (the microscopic imperfections)

all these "holes" allow air to be trapped, even though are very small, it all adds up in preventing the best possible heat transferrence. the idea of thermal paste is to fill these gaps. anything is better at conducting heat than air but the thermal paste's properties is the reason it is so widely used.

but remember if you have a smooth finish you will need less paste
