You could lap it but that would kill your warranty
I was getign really crappy temps when i was over clocking on my strom water block. I was geting 62 load at 350 FSB at 1.40V. I couldnt get it stable over 350. I took off my block last night and notives about 40% of the chip wasnt making contact with the block. I cleaned the chip and noticed that 2 of the corners of the heat spreader were raised quite a bit. I have never seen a heat spreader this bad. I have never lapper a heat spreader. But i decided what the heck i have never used my warantee before (knock on wood).

I started wet sanding the heatspreader. It took me almost 10 minutes of sanding with 600 grit to get to the point where i was actually sanding the center of the heatspreader. I started to see some copper showing in the corners so i started using 1000 then 1500 then 2000 grit.

I reseated everything. and booted up and my idle temps were 4 degrees C lower and my loaded were about 8 degrees C lower.

I cracked up the volts to 1.5 and primed it at 390 and my temps were at 59 degrees. I couldnt even boot this high before.

So if you are geting high temps i would look at your chips heatspreader. If you dont want to lap it then extra AS5 might be your ticket.
