Well I got my new Hybrid 2 days ago and it's silent
Interestingly this one boosts higher than the other one too. Striaght out of the box it goes up to 1366Mhz and if I increase voltage to 1.22 it boosts to 1402Mhz but I hit the 110% power limit often so I might be flashing a new bios soon to stop that happening.
Anyway glad I did the RMA. If anyone else is reading this because your pump buzzes then get the card replaced!
Also I have to say dealing with EVGA was so easy, first time I had to deal with their tech support and RMA team but it was a breeze

Always good to know support is there if I need it from a company, will make me want to by from EVGA again.
