lapping the IHS of a tualatin celery?

MaxMuster said:

well... i have a 1000grit sandpaper here... just want to remove that nasty scratch on the IHS... i guess this is what is preventing proper contact between the IHS and the heatsing

Thats more like it. You don't need to start with a very high grit sandpaper.

removed the heatspreader from the 1.1A Celery (nice small core ), lapped the retail-heatsink... still 60°C under full load @ 1466Mhz/1.675v (29°C case temp)

guess I either simply got a "hot" cpu... or the mainboard reports the wrong temperature...

will get a better hs next week

I lapped the HS on the 1.0a I bought from oldart. It didn't take long, dry sanded starting with 600, then 800, finished up with 1000-grit. Material was removed very quickly, nice copper finish when done. 1420MHz, 1.675v, 44c after running Prime 95 for 2 hours. Artic Silver II and a lapped FOP 38 with a YS-Tech 27cfm fan.
