EK-FC680 GTX+ Water Block Fitment with EVGA Backplate

post #1 of 3
Thread Starter 
I wanted to chime in with my experience on fitting the EK 680 block on a reference layout with EVGA's included backplate.

My card is the EVGA 04G-P4-2686-KR and the block is the EK-FC680 GTX+ (copper/plexi). This is the 4GB version that has VRAM on the back so I wanted to use the backplate. Problem is, the EK supplied screws have too big of a head to fit down into the hole of the backplate so they are too short. EVGA's screws are not M3 size so they do not work either. I went to lowes and picked up M3x6 screws and used those instead of M3x4 screws EK supplies. Pics below on how I mounted the block and backplate.




As you can see below, these longer screws with fit flush with the backplate and not be too long to damage the block. They tightened up snug and worked great.




Here is what screws I used and where. I did use EK's 4mm long screws around the GPU core since they were able to drop into the backplate holes and grabbed snugly.




And finished product.

Nice dude! SOO are you keeping the setup then? Or getting a different block?

Also I just noticed that there are still some thread holes not filled... are those due to the block?

I am not a fan of the CSQ design, but I do NOT have a window in my case so I basically chose the cheapest EK block frozencpu has in stock. The double down firing holes REALLY sucks, but I guess I'm just going to have to deal with it. I'm kinda stuck on EK blocks due to how well my current one works on the 580 and how high flow they are. My pump is a little weak (chose for silence) so that was my main reason behind wanting a high flow block.

About the extra holes not filled. The extra backplate holes don't have the waterblock behind them. There is only 9 standoffs that the EKWB attaches to the card with and I filled all 9 of those.

Edit: If I could have found the non-CSQ design I would have jumped on it. The versatility in switching a port to fire upwards to my EK CPU WB would have been really nice. Now I am digging through my watercooling parts to find a 90 degree barb to run the tube over the card.
