I ordered this block today, along with all the other parts to my new build, to pick up from PCCG tomorrow. I stupidly didn't check if my Gigabyte 7970OC Windforce Rev 2.1 was compatible with it. So I just took it out now and took off the heat sink and took some pictures:

Left one is mine and I've circled the differences I could spot. These are both the same card, same brand, same Windforce cooler, but different revisions!

So...moment of truth. Will the Heatkiller block fit? Images on google show the the right hand side isn't covered anyway, but the newly placed caps on the left hand side might cause problems.

I want to know this so I can change my order before I go and pick up all the parts tomorrow.

Thanks guys.

Unfortunately It seems like its only going to fit the reference pcb.As it says on their website:- Compatible: ATI Radeon HD7950 / HD7970 (reference design)

There is always a difference in factory overclocked PCBs and Reference PCBs and most of the LC Full cover blocks only fit reference designs. I always use this tool to check. http://www.coolingconfigurator.com/step1_complist...

You will probably have to get one of the universal blocks...Hope this thread helps

Yeah Gigabyte recently switched the PCB of the 7970WF3 to the same one used on the Ghz edition. There are no full cover blocks made for it, or will fit it. Even if it would fit over the components the mount holes are in different places. Your only option is to go with a universal block or change the graphics card.

I think of all the 7970's available at PCCG at the moment only the HIS and MSI refernce blower fan models still use a ref PCB

Just picked up 2 of these for my 6950's. There universals and you have to cool your vrm's and ram separately but they should work along with the other universals.
