Issue with EVGA GTX 580 and EK fullcover / backplate

post #1 of 7
Thread Starter 
I hope this is in the right place!

I have a reference design EVGA 580 with an EK full cover block on it (I bought it off eBay with the block already on). I picked up one of EK's backplates and when I tried to install it, the three middle screws that go straight through the PCB and into the block seem to be ~2mm too long. I took the block off and all the pads and spacers were correct, so I rebuilt it only to find the same problem.

Now I also have a 580 from Gigabyte (also reference PCB) with the same block, although this one is the old Nickel + Acetal vs. the EN + Acetal on the EVGA card. I installed the block and the backplate on this card without having any problems...

All the screws that came with the backplate are 12mm long, so I don't think I used the wrong screws in the wrong place, and when I had the block off I was able to thread the screw all the way to the bottom of its thread in the block... maybe the newer EN blocks just have bad threads.

Anyone with EK VGA experience ever run into this problem? I guess you'd sorta have to use an EK block to understand the issue I'm having.

So the issue is the screws are too long and will not sit flush against the PCB, or the GPU is not making contact?

The block sits well against the GPU/Memory. The problem is with the screws the mount the backplate to the top of the card. Typically in this situation I would dismiss it as a mistake on the part of the manufacturer shipping the wrong size screws, but the curious thing is that my other 580 is basically the same card with the same block/backplate, and the same size screws fit perfectly. Here's a pic:

I cant see why there would be such a difference, unless there is some tolerance in the backplate/screw/block. Maybe the thread is damaged so the screw will not screw down completely?

Yep. I ended up shaving a few mm off with a bench grinder, and now they fit perfectly. Still interested to hear what EK says about their manufacturing tolerances though!

EDIT (Jan 30): EK replied to my ticket and told me that they updated the block design and started shipping the new spec backplate screws with the block itself. Doesn't make much sense, but at least that explains it!

funny, I had the exact problem!! I had some extra screws from my EK block that were shorter and it worked perfect.
