Hi everyone, this is my first post here. I would like to hear from everyone else who did the same. I recieved my HD 5870 2 weeks ago and decided to replace the thermal paste with some AS5. I removed the cooler, then the paste from the gpu and cooler, then i saw what the base of the cooler looked like. I think ati just machined off a piece of copper and stuck it on. I am going to lap it today and see what happens. I wil also post before and after photos
Please, keep us informed. I have the same problem. The cooler base is pretty hard to lap, because of soldered bolt-through parts.

I saw the same thing on some 5970 review, the heatsink base looked like c.r.a.p! But maybe that is due to card being a sample straight from AMD.

I am finished with it, I need to make the pictures smaller to upload. Idle temps went down 2degrees, max temps went down 8degrees. I am verry happy with that. The card now does not go over 70 in games

would be nice to see how much higher an OC you can get with it.

Was this with or without new TIM?

Even before I did the lap I could go to 1050 core and 1300 mem, my temps ar just a lot better now. I used AS5, so that also helped. Has anyone else maybe tried it, and what was your results. On a side note, I am very impressed with this card's performance

Thanks for uploading the pics, I am having trouble doing it. Do I have to copy and paste the url or how do I do it?
I did some lapping myself and here are the pictures:

First thing I noticed is that temp difference between GPU Temp. 1, 2 and 3 from GPU-Z readings (Crysis - Lost Paradise) went down : from max 12 to max 6.5 degrees Celsius.
