How much can lapping the heatsink do ?

post #1 of 5
Thread Starter 
I am thinking lapping my heatsink (not the cpu yet...just in case it get burned out and i need to use the warranty)...

but how much CPU temp drop am I looking at ?


also. my room temp is around 24c and my core temps are 44, 42, 39, 39. is that too high ?

Are those temps at load? If not what are your load temps. Some people see up to 10c drop off the load temps. That is also if you have a lapped CPU. From my experience Zalman's bases are already very flat my old CNPS9700 and VF900 are flat except for the very outer edges.

Depends on the HS, but you can see 3-7c drop in load temps.

some heatsinks need it more than others (yes true im looking at you) but going of your temps i guess you would only get min gains as zalmans tend to be good at making flat bases for their heatsinks.

try it and let us know.

You probably won't see that much of a drop, the Zalmans already have a mirror finish. I tried lapping mine, I didn't see any difference.
