7950 Heatkiller 60-DIY Block...need help.

post #1 of 6
Thread Starter 
I ve installed the GPU-X Core LT block and heat sinks to the VRMs. I m trying to apply the 60-DIY to what I believe are the voltage regulators on the back of the card. Problem is, the person I saw with a similar card has slightly more room than I and that throws this design off. For those not familiar I can cut the copper base plate to any shape I want and use thermal pads to contact what I want actively cooled. The dimensions have to be the same size or larger than the black acetal block that is attached to the copper plate.

The long slender red outlined block towards the back of the card is the area that should be cooled. The problem is that the modules slightly past it are 1-1.5mm higher than the regulators (not sure if that is proper). I m unsure as to whether I should use one large heat pad and just pray it contacts the front enough to transfer heat, or if I should grab a 2.5-5mm thick pad to make up the different and use a .5mm pad on the back items.

Outside of the above option all I can think to do is possibly have a custom copper block CNC'd that only touches that part and raises up to the full acetal size while not touching anything.

Why not just use a proper 7970 full cover block

Because this is purchased and obviously in front of me. I wanted to use this for future video cards as it would be cheaper, but this is my one obstacle that I did not calculate for.

Yeah, I get that but surely having a VRM block CNC'd for this one would counter any savings.

I guess your best bet is to shape that piece exactly the same as the VRM block on the FC7970 blocks. It will be difficult though, it has a very narrow raised centre section that contacts and the rest of it including the 2 mounting screw areas do not.

CNC doesn't usually cost me anything but shipping and time. Best friend has done it since he was a kid, but I wanted to avoid the delay and complications if possible. Trust me I am and have considered a full block, but I d like to find a way to make this work. I may just stick heatsinks and a fan on the back of this card.
