Hello,

I have a gtx 770 that I have modded to have a corsair h100i mounted to it. In the process of doing the mod I mounted copper heat sinks on the ram and vram. I used a ceramic epoxy, making them to my understanding more or less permanent. I now have a bug to do a water cooled set up and i want to put a water block on my gpu. My question is, does anyone know if I was to cut the heat sinks down to the height of the thermal pads if this would work under a water block? Anyone know a way to remove ceramic epoxy? Anyone want to buy a modded very fast, very cool gtx 770 h100i included? I know it would be easier to get a new card and start fresh but I don't have the budget for that.

If you have any thoughts on this let me know.

Thanks,

if you use a full cover block you HAVE to go to the pads

Yes, I understand this, what I was thinking was cutting the copper heat sinks down to the size of the thermal pads. In effect making copper thermal pads. Would that work?

no it would not however you should be able to dissolve the epoxy with acetone however just make sure you work in a well vented are and let if fully dry before testing it.

Really? Thank you for responding btw. Well ventilated is not a problem, are you certain acetone will dissolve the epoxy? I used Arctic Alumina, Ceramic Thermal Adhesive to attach the copper heat sinks. Also, acetone will not damage the ram/vram?

no it will not and it should work since it is still resin based and that is what it will disolve and it is safe for a pcb just try not to get it on the bare gpu

From what I am gathering from research, acetone will loose uncured epoxy but not fully hardened epoxy. This has been hardened for a few months.

it should be strong enough to disolve it though it might take seval aplications and i do not know of any stronger solvents that wont damage the pcb

Let this be a lesson to others to not do this, full cover block and proper pads in the long run. Also experienced modders don't use epoxy on vram unless on cheap crap cards. BTW when buying a new card one thing to look for is if the card has a discrete mid plate that isn't apart of the overall stock cooler.
