When you Lapp, the CPU has got to be 100% flat to the lapping surface, and the lapping surface has to be 100% flat, but since you're already into the copper, you need to exercise some serious caution. I'd test fit the heatsink to the CPU and check the contact footprint between the heatsink and CPU before going any further, it would help if you could post a picture of that also. | Report abuse Bims April 25, 2010 3:47:42 PM Well, it don't touche at the edges. Do you want me to take a picture of it with the cooler over it, from the side? Because it is pretty hard!... | Report abuse 4Ryan6 CPUs Authority April 25, 2010 3:56:19 PM No, remove the heat sink and take a picture of the thermal compound footprint on the CPU heat spreader. | Report abuse Bims April 25, 2010 4:03:17 PM Ok. I have not tried to put it into the computer yet because that I haven't received all the parts for my system. But if you like I've try to put some thermal compound on anyway. | Report abuse 4Ryan6 CPUs Authority April 25, 2010 10:23:23 PM Don't you have the motherboard and heat sink, it doesn't have to be in the case to trial fit the heat sink. | Report abuse Bims April 27, 2010 9:27:42 AM Hello again. I found a Pro to it that might help me. I'll write back how it went. | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>CPUs>Lapping CPU - but get round edges!> Related ressources: ForumCooling Fan Roundup ForumThermal Compound Roundup ForumCooling Fan Roundup ForumThermal Compound Roundup ForumCooling Fan Roundup ForumThermal Compound Roundup ForumCooling Fan Roundup ForumThermal Compound Roundup ForumHow much of an effect can lapping a HS and/or IHS have?
