His grit suggestions are great and as long as you are not going too deep into your block to fix the concave, you should be good. How deep is the "crater" in your block? I am assuming it is just ever so sublte.

Contrary to what slaughtahouse said, you want a nice flat surface to work on. Purchase a sheet of glass to work on, or your most likely non level surface will become the basis for you block surface. Also purchase a razor blade to check the final product for irregularities. (They can be purchased at walgreens)

I mean no disrespect I just do not want any expensive components to be ruined by cheap advice.

Thanks -__-

A) I never said you wanted a non flat surface to work on and b) I didn't do it for just the look. I'm just saying, it didnt do much besides give me a nice look.

Also, if I knew the grit of the material I was using, I would of stated it.

And about the temperature of my results. I have a fan curve on my gpu you know. So regardless if there was or was not a change, it's hard to tell because my fan would just run a bit slower or faster. Besides, if you do a really good lap, you're are only looking at a few degrees in temperature change at most.

I appreciate you undermining me. Feels good.

Looking at that picture... shouldn't all of that ugliness be fixed just by simply using some random sort of metal polish sold in the cleaning products area of the supermarket?

If his only goal was to clean the copper plate then yes, any household polish would work. Heck he could use ketchup or lemon juice and get a nice clean shiny surface. However polishing/cleaning wont remove the tiny scratches on the plate nor will it remove the concave shape of the copper plate. Lapping will remove all those tiny scratches and flatten the plate hopefully making heat transfer more efficient.

But the CPU's IHS itself is not flat. It's usually concave and needs a convex cooler base for best contact. Lapping the cooler's base and making it flat might make the contact worse. That feels dangerous.

lap both sides of the equation, or remove the IHS entirely(best option thumb.gif )

If you lap the block with the base plate fitted you will definitely lap out the bow in the block and decrease performance. It might only be a couple of degrees but it will be worse. The bow is formed by the o rings so removing the base plate and lapping it separately will ensure the bow is formed again once it's lapped and refitted.

The oxidation on the base plate will not affect temperatures and doesn't even need a polish. You don't need a mirror finish and 800-100 grit is enough.

Interesting, So the bow/convex/concave on the cooling block is done on purpose?

It makes sense, I have seen this used in industrial applications but torque spec and tightening sequence are crucial. So how do companies get over the fact that every IHS seem to be different as far as surface shape? I have seen IHS that have a concave some have a convex and some are rather flat. Do cooling blocks have a torque spec? I mean if a cooling block is suppose to be tighten down so the bow/convex/concave flattens out wouldn't there have to be a torque spec? too little torque would cause a pocket and too much could deform the IHS/CPU. Again my small amount knowledge on the subject is in industrial application so maybe I am just overthinking it.

Sorry, I truly didn't mean to go off subject I am just really curious.

The bow is designed into many blocks. In fact with the Aquacomputer Kryos the user can add a thicker o ring to increase the amount of bow. While I wouldn't say it's random I've seen enough CPU blocks to know that the bow isn't perfect and varies in degree from block to block so the torque spec is pretty much irrelevant.

To the best of my knowledge it's only done on CPU blocks, not GPU full cover blocks.

I picked up 400 and 1000 grit at my local walmart in the automotive section. The hardware section did not have the same sandpaper grits, go figure!

Using my Hyper 212 Evo with 1000 grit I got 4c drop. Was happy with that for about $7. Even got sandpaper left over for other coolers thumb.gif

So you're saying take the screws off the cooler and just lap the plate? smile.gif

I understand that the convex is right, but I just want a nice clean finish. tongue.gif
