GPU backplates - do they prevent warping?

post #1 of 3
Thread Starter 
I have two reference 7970s with EK water blocks. Due to multiple factors (stress from the connected tubing, weight of block itself, etc) it looks like the PCBs are flexing downward a little bit. As soon as I noticed this I immediately removed the cards from the loop because I do not want to damage anything. There's an EK backplate but I'm not sure it actually helps keep the PCB straight because it only has 4 screws that attach to the 4 corners of the block, instead of corners of the PCB that are not covered by the block. Does anyone know of a backplate that actually forces a PCB to stay completely flat?

Since the gpu is screwed onto the backplate, you would have to bend the steel to bend the pcb. So yes it adds a lot of rigidity to the gpu pcb. They are also quite cheap so grab yourself some. Can help lower temps also.
