Hi,
I recently had my 970 Hybrid Gaming RMAd. I received a brand new card, I think (has a -KR suffix).
Problem is, the new one has the exact same issue with the radiator fan: after about an hour of low-load operation or immediately under high load the fan starts to emit a grinding/gurgling sound. The radiator is installed horizontally in a top vent of my case.
The card is operating fine otherwise: GPU delta temps are around 20-25°C under load, and the blower fan and pump on the card are completely inaudible (as are my 4 case+1 CPU fans).
Is this really the normal noise for these cards?
Is anybody else experiencing similar issues with their hybrid cards?
