GTX 670 PCB bending

post #1 of 25
Thread Starter 
Hi. After setting up my CPU + GPU water loop, I noticed that my GTX 670 pcb is bending due to the weight of the waterblock + a bit of excess tubing. My question is: would this eventually break the pcb if I leave it like this? Would performance decrease because of this bend?

Thanks for reading.

That's a nasty bend you have going there, I would't worry about performance decreasing but breaking under the weight could happen i suppose, you need to take some of the slack out of your tubes going into the card to try and put some lift on the card.

I agree frown.gif. I knew i should have invested in some quick disconnects. This is going to be a pain to take apart and re-loop just to fix this problem. Anyone else?

I just removed some PCI expansion slot screws that way the PCB won't bend back up. What do you guys think of this?

Put a backplate. Maybe after some time to get back to normal.Maybe your tubes pushing down your card hard? Thats a pretty big bend

there is little stands that you can get to keep your cards sitting right. You just sisuate them under the card. But I cant remember their names. redface.gif

Thanks for the responses so far. I'm just wondering if there is a chance my card will break over time. If these PCBs are tough, i'm not going to bother until next time I flush my system (in half a year)

Agree get a backplate and you should be fine. That is what I had to do to my Crossfire Sapphire HD 7970 setup. And truthfully I think they looked better with the backplates anyway.

I would run a hose out of the bottom of the card. That might help push the card up a bit. Thats more sag than I would feel comfortable with.

that is near breaking, you must take the extra slack out of the tubes or risk snapping the card.
