Thanks for the advice. I've opened the side and I'm pretty sure there's no cable hitting the fans. Custom fan curve is worth a shot, just need to learn how to do that :P. Do you know exactly what rpm you kept them in at idle, since I know literally nothing about this?
I am tempted to RMA it. But the card seems to be functioning fine, and temps dont seem too bad (but not impressive either, hit 80C the other day). I ordered from Amazon UK, so if they themselves can test and replace it, I'll do it. But if I have to send the card to Gigabyte, I'll probably keep it, see how it goes, and RMA later if it actually stops functioning inside the 3 year warranty period. Thanks for the advice mate.
