How to get heatsink to touch on a 9700pro?

[airwolves]

Well I have problem of my computer locking up when playing CS. I did have it in the past but it would restart, like give yu the blue screen and reboot. but that time it was Nvida drivers.

NOW it just freezes on a screen and I have to pull the plug to restart. While it was locked up I checked the cpu heatsink and it was cool to touch. And I checked the back of the 9700pro It burned my finger its so hot that I cant keep it on there for a sec :( Wander if that might be my problem or they just run hot?

Ok took the heatsink off and THERE IS yellow sticker paste that didnt touch the heatsink, looking at it the center of the core is below the outer edge lip. So adding compound would do nothing :( it touches the outer square ring before the core :( Wander why?

I put some thermo contact stuff over it to see if it help tho. as the yellow stuff didnt even touch the center core.

NOW it gives odd colors at times and colors on walls go black look like I did something wrong. :(

Whats the crome ring around the core? Or do I need a new heatsink thats center is offset?

You need to add a shim under the heat sink.

remove all the yellow TIM from under the heatsink and offf the GPU. I shim can be made from aluminum or copper. I never made one from foil but a soda can might work as it is about the perfect thickness.

I'll begin by stating that I did not need to do this to my card, but was prepared to...and have read that others have removed it sucessfully.

The square frame you see around the GPU on these 9700's is sometimes on a higher plane than the surface of the GPU as you have experienced. THe only negative i have discovered on these cards so far. You can:

A) Shim it, which adds two additional thermal impedence layers (cooler-paste-metal-paste-GPU instead of cooler-paste-GPU ) that will interfere somewhat with good thermal transfer, but works.

Consider that one of the best ways to insulate (retain) body heat is to layer clothes, same principle applies here (more layers is equal to less heat transfer is equal to lower overclock) or:

B) gently pry up the square around the GPU and remove it to allow full direct (use paste though) contact with GPU. DO NOT scratch the board during this process (you can use folded paper to pry against.)

I believe the square is there (just an educated guess) to help keep extreme pressures off the GPU and to minimize that chance of uneven pressures on the corners of the GPU. So if you remove it and are very careful in your mounting, you should have no problems, but if you overtighten or torque your pressures unevenly, you could be asking for trouble at the corners.

Option B is a somewhat xtreme mod, but that's what we are in this forum for, right?

Downside is you DO risk damaging the board and superglue and and RMA's are a then possibilty in your future.

And heatsinks for the memory is virtually a must.

Good luck, and feel free to PM me if you like as I have generally maxed this baby out thanks to help from DDtung, Chong345. Mr Iceee, and others.

With volt mods I have achieved stable 430/379 timings out of this card (water-cooled).

Good luck!

If you're looking to really push your Radeon 9700, perhaps with an after market cooler, this is something that can potentially stand in the way - so now you know. Heatsinks like Zalman's ZM80A-HP however, have the necessary undercut (about 0.3mm relief) to fit properly on the R300 core without having to use a huge amount of thermal compound.

this is wat they said at the end
but..
check this one

One issue you might come across with installing this unit on a Radeon 9700 as I have is the fact that the GPU actually sits lower than the frame you see around it. The Zalman manual actually mentions this, and suggests that you use slightly more heatsink paste than usual. This is not quite optimal, but you'll find it to be satisfactory in this case.

i don't in who i should belive, i'm from portugal .. and i still haven't found ZM80A-HP in any local store to see who's right
