Modifying my CPU Heat Sink???

[mattydies]

I have an "Arctic Cooling Freezer 7 Pro" as my CPU cooler.

Arctic Cooling Freezer 7 Pro LGA775 2500RPM 45CFM - DirectCanada


I received the item it appeared to be nicely made, however I did notice slight lines on the bottom of the copper base - surely from the machining / manufacturing process.

The lines are small enough to be acceptable, BUT I could sand them off (perfectly flat surface and sand paper start at 320 then get finer and finer - I have tonnes around as I am a huge car enthusiast).

Could this provide better contact for thermal conductance? (IE Lower CPU Temps)

I am FAR from having issues with heat, but if it would be a slight improvement I will gladly do so.

The price is right

There is a process known as lapping that will reduce the temps of your CPU. Here is an article that shows you how to lap your heatsink.

QFT.

That's basically what I was going to say but he's saying it better.

Also you don't need to start with 320grit, you can start with 800, then go 1200, then 1400, then 2000, and use the micron grits if you have any for shininess (although the shine doesn't change the thermal efficiency, it's purely for bragging rights.)

I heard that lapping WB wasn't a good thing. But never heard anything about lapping an heatsink. Should be a good thing. I think...

Yeah Lapping will help a bit very minor though still it all adds up.

I will be lapping my CPU Heat Sink one of these days when I have some excess time.

Thanks for the URL and everyones help

How would lapping a waterblock be bad? All lapping does is make the base smoother and flatter to allow more contact with the CPU (or other thing, ie SB, NB, w\e.). The only waterblocks I know of which arn't supposed to be lapped are Stinger waterblocks, because they are perfectly pre-lapped and the copper base is so thin that lapping it any more would expose the inside of the waterblock's channels.

Go tell this to XS members...lol

Well I'm not a member of XS so HAH!

lol.
