Hi have two GTX 760s in SLI. Work great, fans are working fine, temps are fine. However while under load they start to make a fluttering sound. It is the best word I can use to describe it. I tested every other fan in my system individually, and no sound. I turned the GPU fans to Max while nothing was running and I get no sound. But while under heavy load, a fluttering sound comes from the GPU area. Is this normal/okay? Any fixes? Will it damaged my cards/machine?

can you try to manually adjust teh fans to see if it goes away while playing? I'm thinking maybe the temps are right at a point where the fans need to speed up but once thay do teh temp drops to a point they slow down creating teh up and down effect your hearing. to test this just up the fan speed and see if it persists.

It's probably "coil whine". As the load on the VRM's change you hear the pitch of the whine change making it sound like "fluttering". It won't damage the card, however it can be distracting. Not really much you can do. You can isolate the card doing it and see if the manufacturer will RMA it for "coil whine". However I seriously doubt they will unless it's causing a problem ie. crashing, artifacts, spontaneous reboots etc.

Okay. That is what I have been hearing it is. But you are sure it won't damage it? Even over time? I don't think they will RMA so no real way to fix it huh?
