Someone needs to try this on a dual gpu card. I doubt it can be done on my 5970 since the chips are so close together.

ok,

I just woke up, so the pc is cool. Ill run some BF3 and ill then post my load temps.

Room temp 73f
idle temps

gpu 26c
memory temp 35c
power temp 28c
board temp 16c

Both fans on the shroud at 20%
H70 rad fans 1100 rpm (im using both fans from the H100). These rpms are locked at this rpm with a fan controller.

These are load temps
20min play time and card factory stock

gpu 50c
memory temp 63c
power temp 56c
board temp 27c

BF3 Ultra settings, 1920x1080 asus 23" screen

Three straight hours of bf3 and my max video ram temps were 68c average 63c, card remained at 99% usage the whole time. gpu temp maxed at 56c and 90% of the time it was 37c, board temps were a constant 27c and power temps were constant at 33c. This card is running at close to the same temps as my 1055t processor which is overclocked to 3.92GHZ. Max cpu temp was 34c

At this point i have no fear of causing damage to the card, it performs better than i could have ever expected.

So some time has passed and my mod has worked amazingly. In the past little while i have noticed that my temps have slowly started to rise on the gpu. Nothing to be worried about as I just reached 62c for the first time but consitering that my regular temps are 42c its abit of a change and im sure its the cheap TIM i used. Some daytec stuff i bought from Future Shop when i was in a bind. It had the consistancy of milk to be truthfull. Im sure some of my super high overclocks were responsible for this "cooking of the tim".
I stopped by my fav local pc shop to see what they had for new tim and low and behold they had Artic Sliver 5....3 gram tubes. I picked up a tube and on the way home grabbed some zipstraps. I had a moment while wandering the store...i saw some sandpaper. Ive never lapped anything before and thought if i was going to bust the card down i may as well give it a go. Now as i got my lab ready i had a horrable thought, a horrable awful wonderfull thought. There is a thead here where cakewalk popped off his heatplate covering the acutal chip on the graphics card, can you see where im going with this lol

So here it is. Part 2 of my build log

In this installment ill be removing my IHS (intergrated heat spreader) from my 580 Matrix. Ill be lapping both surfaces and also lapping the surface of my H70. I will doing the TIM on all surfaces with Artic Silver 5. I wont lie, it scared the crap out of me thinking of hitting my gpu with a hammer to sink a razerblade behind the IHS and NOT hitting a resister. Not doing it would have bugged the crap out of me even more...this is what i do, i mod. So here we go along with some nice pics to prove it all.

First shot. Ive removed the H70 pump cutting all the zipstraps, not much to see as ive removed the old tim now. Its more for a comparison shot for later.

Now i know this hammer looks old and rusty but trust me, it still works well. I tried tapping with a small wrench but i was not getting anywhere. I went to the shed to get a proper hammer. Took a few minutes to get the razerblade in far enough to pry off the heat spreader. Pretty neat stuff here, never seen this for real, only pics others have posted. Looked to have nice spread of tim and no issues i could see. No turning back now.

Look at how ruff the surface is here, Im going to clean it up and lap this surface. Being ive not done this and i forgot to look up lapping before starting i had to wing it...

IMGP0322 by cravinmild, on Flickr

Nothing really here, its a chip...KIDDING nvidia, its really cool as its the heart of my 580 your seeing here, its going to look even nicer once i clean it up.

And here it is all cleaned up, nice and shinny too

IMGP0325 by cravinmild, on Flickr

Now i will admit, ive seen better lapping jobs. This was the best i could do with the time i had. I started with 400 grit and finnished with 1200grit. Its still better than it was before IMO

IMGP0328 by cravinmild, on Flickr

This was much harder to lap as there is a lip around the spreader. I had to cut some chunks and rub the inside with my finger. The outer edges are still dull but compaired to the gravel surface it was before im pretty happy with how it turned out.

IMGP0329 by cravinmild, on Flickr

Now the H70 did not come out as nice as i hoped, the original finnish had really deep lines in the surface. It was shipped that way and were not scratches, just the way they are i guess. It took ALOT of time to get it even this smooth, i used most of the sandpaper on this part of the mod. I also took alot of surface off, my screws are much closer now. I saw a definate dip to the middle of the surface, not flat by any measure.

IMGP0332 by cravinmild, on Flickr

I started with the pea size drop the first time but i was not happy with the results when i lifted up the heatspreader to check it. I wanted it right the first time as this is more than a simple re and re to get back to this point. I ended up trying several methods here and ended up using the credit card method to spread the tim across the whole surface and then adding a small dab to the middle for good luck

IMGP0336 by cravinmild, on Flickr

Here is what the pea method did for the spread...Not to good imo

And here we go, all back together again.

Thats it for the pics, proof indeed lol
Ive only started the pc and did this update so far. Once the kids are down and im sure its not going to blow up ill try some stress tests and see what the new temps are. I dont know if this has cure time but ill not be going for a oc tonight, just benchmark the card for now at stock. So far the temps were 26c on startup but now sitting at 31c pretty much the same as before, its the stress tests where ill see if there is an improvement. I left everything the same as before the re & re so i could see if there are changes so fans are still 1200rpm and the pump is still set the same off the fan header to the mobo. Room temp is 78f right now....i was cooking dinner and using the oven. Ill post back once i get a chance........

Cravin, I suggest you sand down the edges of the heat spreader alot more.

As you see in guide pictures I sanded down the edges of the heat spreader alot more. Also did you scrape off some of the glue on the silicon? The black stuff?

Yours:

As you see there's barely any TIM on the heat spreader, that's the point, the surfaces are in contact with eachother, the edges of the heat spreader don't even hit the silicon anymore, or if it does, its not the main point of contact. It looks like the edges of your heat spreader are hitting before the heat spreader center is hitting the actual chip, hence the need for sanding it...

My lows have dropped but it was also cooler outside last night. The spread in the TIM is what one would expect when using the pea method. I used the card method after seeing how the spread worked. There is a nice fit here as you can see in the outer most area of the ring spread...its perfectly thin. The middle is only upset because of the lifting of the spreader to check.

Now with that said if i can get better ill be redoing it again. The spreader was not glued down and ill get another go at it.

I used the credit card method and spread it evenly, removed and checked again, looked pretty good to me.

The test will show though right and i plan on doing lots today. ill post back.
