I sold my 780ti in January and bought a 1070 hybrid, RMA loud pump.
Received a new card, same scenario. Back to EVGA, the received a 1070 FTW Hybrid.
Same problem. Decided to wait, and stepped up when i had the chance.
Its easier to live with a card that is whisper quiet when idle, and then noisy under load.
Than an irritating buzzing all the time
