Perfectly Lapped Surface ? [NH-D14] [HELP] - Page 2

post #11 of 17
Looks perfectly fine to me. The drop of water with the glass and the drafting ruler are both good tests of flatness. I do not think you are going to get better results manually.

Anything over 1000 grit is cosmetic; you aren't going to see any measurable improvement from going further, but it shouldn't hurt either.

jsut use 2500 grid now.. it's far from being perfect.. it should be the exact same thing as a mirror. it's not even close. it look likea blurry dirty mirror...



2500 grid is smooth when u touch it. It feel like a cloth. So keep on working tongue.gif

EDIT: yeah you won't really have better result with true mirror finish. but why won't you finish the job when you can? it's nice to see a fully lapped HS tongue.gif

Because it's a lot of work and no one is going to see the base of your heatsink after you mount it?

Hi Flisker_new and oc .net members smile.gif

I am eager to know your results after nhd14 lap.In case your results are not positive ,i suggest you to use a good TIM like " Coollaboratory Liquid Ultra"
and create micro-grooves (no polish miror).bulb.gif

may the fourth be with you. thumb.gif

From noctua web site: Why doesn't the base of Noctua coolers have a polished, mirror like finish?

As most of today's PC enthusiasts use high-viscosity thermal compounds, the contact surface of Noctua coolers is optimised for use with this type of pastes. The micro-grooves at the contact surface ensure that high-viscosity thermal compounds are dispersed to a uniform thin layer across the whole contact area and that no air pockets remain between the cooler and the CPU. With a polished, mirror like surface, the risk of uneven dispersion is much higher. As too thick layers of thermal paste and air pockets drastically deteriorate heat transmission, the micro-grooves are is of vital importance to the overall cooling performance of Noctua coolers when used with today's high-viscosity thermal pastes.
