After reading some posts, I realized that I may not have done the lapping correctly, as I sanded by simply holding the sandpaper with my fingers. The wording used in the instructions made this somewhat misleading for me, as it refers to "the glass surface", not "a glass surface", which lead me to believe it was referring the the cooler head/IHS itself.

I lapped the IHS the same way -- I didn't remove it; instead, I kept it attached to the die (because I didn't want to remove it), and just lapped it like that with sandpaper.

Should I pull it out and re-do it, or just leave it how it is? I still don't want to remove the IHS because of the possible damage it could cause..

Is it possible that I actually made the heat transfer worse that it already would've been, or is that unlikely? I was pretty satisfied with the surfaces once I was finished, but of course I can't tell exactly how flat it was at a microscopic level.

hmmm.... I'd just concentrate on the heatsink surface. And Yes, the SAND PAPER should be on a glass surface. Then the heatsink/IHS should be sanded on the sand paper that's on the glass. What I would do, if you have enough thermal paste, apply the heatsink, then pull apart the heatsink and see if the two surfaces have little thermal paste between the two, if you notice one area on the chip has more paste, it should be noticeable, then you might want to consider getting some type of narrow but flat stick and wrap the sand paper around that and sand the IHS.

hmm...Bummer man.

Take off the IHS! hehe

+1. from 60C load on my 470 to 47C load at stock voltage/clocks. IHS sucks.

I will take off the IHS. When you sand the cooler head, do you rub it slowly back and forth against a table, or do you move a block of glass across the cooler ahead? In other words, which part moves? The cooler head, or the sanding material?

Also, if I don't have a block of glass, a glass counter, or something similar, would a wooden table or composite counter-top surface do?

I was lucky. I found the mounting base for my navigation that stickys to the dash. Its a large round disk, completely flat with sticky tape on the back. I peeled the prective film off the tape and put a sheet of sandpaper to it. I then rubbed that back and forth across the pump head. For the IHS (was easy cause it was removed) i just rubbed it back and forth over the countertop on a piece of sandpaper. The inside of the IHS was hard. With the tapered edges i had to find a roll of dimes and then cut a small piece of sandpaper which i put into the IHS and rubbed with the roll of dimes. You wont get the inner edges but it worked for the middle part. In the end it was all for nothing as i now dont even use it (the ihs) and just put the pump right to the chip and tighten it all down.

has anybody found a way to mount the Cooling shroud back on the cards. like GTX470,480,570 or 580 cards?

I don't see why you couldn't just cut out the shroud? Surely others have done it..

You could, but anything that serious would void the warranty, cutting the shroud up with a giant hole in the middle = shroud modification = physical modification.

Now if we could cut two small holes that could pass the tubes through and still have the shroud close, that' be killer! rolleyes.gif
I hope somebody comes up with an idea, I hate to keep my card naked, and I guess the fan would be more effective with the shooed on
