Couldn't using really high grits net worse performance than stopping at a low grit because The high grits will leave smaller scratches in the metal than any tim can fill so when you apply tim it stays in a thin layer instead of spreading into microscopic scratches and thus acts as an insulating layer between the cooler and ihs, and even though the metal is extremely flat it still won't make good enough contact to run the heatsink with no tim.
im starting to think the cpu was meant to be lapped straight out of box, and the only reason for tht nickel coating was protection in storage and shipping. otherwise y wud amd or intel ruin good conductivity, im also thinking i shud have reasized this a long ass time ago haha
@kenmha I Finished the lapping after this video and havent finished video two yet, but watch my video on thermal interface material application and you can see the mirror finish of this cpu finished
your better off to start higher grit because people tend to push way too hard when lapping and all the force you want to use is the weight of the processor itself, and if you use a lower grit it would give you more resistance and force you to press harder
Also I am no lapping guru, but knowing how heat transfers through thermal conductivity, the flatter the surface is the better it will perform. Regardless of how shinny it is, any scratch marks left from sanding will produce mixed results. Even though they are barley visible to the naked eye. but put under a microscope those barley visible scratches will look like huge canals. Was that the final result after using 1500, 2000, and 3000 grit paper?
i consider mirror and smooth two different things, if you get anal about a mirror reflection and use pastes, ect... those microscopic scrathes that you refer to love to house that crap and can be detrimental to the thermal conductivity your trying to obtain in the first place, and the stock HSink was for demo i hadent received my other heatsinks yet i show in some other vids
I agree about the difference between mirror and smooth, but you don't need to use paste or any other medium to get a mirror finish. Using 2000, 3000 grit wet sandpaper will also give you a mirror finish, heck I've even gotten a mirror finish just using 2000 grit as the final stage, even though I still would like to say that just because it's mirrored or smooth does not mean that it is completely FLAT! would you not agree.
yes, scratches will be huge valleys under microscope but the paste will fill them~
but if the CPU and HS are not lapped, there will be mountains cos its not flat and pastes will not fill them up cos its mountains~ and there will be uneven contact spots between CPU and HS~ if you notice, the paste will be thicker or thinner at different contact spots or there will be spots where there are no paste cos its not spread out evenly~ if you lap, it will spread out 100000% more evenly~
every time i jumped/seek the video forward he was saying "ahn"
LOL
Anyway, good job!

this lapping business looks effective,as for the method,why not use a dremel drill with a polishing bit?would it work?

@stuart38 I dont think that would achive an even "clean", as the 2 flat surfaces
against / supporting each other.

Is that good for the processor?? I mean look at all those scracthes thats on the surface

Why would anyone lap a stock heatsink? lol

no i havent been able to finish the second video yet, you can however see the result on my thermal interfarce material video

lots of people go to a mirror for no reason really.
d0rkiishchris 2 years ago
use alot higher grit
i start with 220 you NEED TO GET RID OF THE SHIT then smooth out the fine ridges from the 220
if you dont start with 220 your wasting your time

agreed i will never start out where i did again hehe took forever.
cursed1815 2 years ago
@cursed1815 not somthing to agree with. its a fact thats what you need to start with lol
in my head its a fact at least

yes mirror finish is not required,
cursed1815 2 years ago
I never lapped to a mirror finish. As long as it's lapped dead flat thats all you need.
