CPU Laping

[SImoHayha]

I was wondering if Laping would help CPU temperatures by a certain degree. I have practiced using an old Pentium 4  and I have a soft foam and the original FX CPU case so that way the Pins don't bend. Has anyone tried this and see reduced temps ? Also I was thinking of doing the same thing for my CPU cooler.

Theoretically you could with some fine grit wet sandpaper but it wouldn't really make a difference in temps since it's originally pretty flat already and the thermal paste is designed to fill in the pores or gaps in the metal.

try but more metal to metal contact is better than metal paste metal, how much i don't know.

can you explain lapping to me? i've done a search, but i don't quite understand this.

 

is this grinding down the CPU lid in over to add micro heat fins?

Laping is basically grinding down the layers of aluminum until you reach the cooper layer which is suppose to help with temps because cooper as you know is very good at conducting heat. So when you grind it down and place a heatsink on it it should be falter with the surface of both CPU itself and heatsink you have thus providing more metal to metal contact with the help of course with thermal paste

i like this.

 

adding this to my list of shit to do in my dream build.

delid and lap.

Well, main reason is to remove abnormalities from the IHS (caused by manufacturing processes or delidding via vice method (though on this one you sand down the inner side too)) like scratches or bumpy surface.

Also it isn't aluminum, it's nickel, if the CPU is perfect flat I'd be useless to reach the copper.

 

Seeing that you're interested in this, if you're sanding the CPU you'd sand the heatsink too to make better contact, though don't sand them too much, as you will increase the distance between them.

In theory yes but as long as your thermal paste isn't exceedingly thick it shouldn't make much difference.

Mainly to flatten the IHS and the coolers base plate as others have said, the best it to use fine grit wet sandpaper and grind the surface along a sheet of glass or a surface plate that is very flat.

The answer to whether it's worth it is actually going to depend on the CPU cooler you are using. In most cases you will see an improvement, and, if Silent PC Review is to be believed, it can be significant. I've heard of lapping with regard to CoolLaboratory's thermal compounds -- the Liquid Pro and Ultra -- as a means of maximizing how well it works. If you're using an AIO or water cooling, this can ensure you have an even, flat surface for contacting the water block.
