My Asus 6950 DCII makes a very strange metallic grinding sound, but only within a very narrow range of fan speeds.
Here's what happens:
Normal sound at 0-49% fan speed
Strange metallic grinding sound from 50-52% fan speed
Normal again from 53-100% fan speed
In the video below, the first ~6 seconds are at 49% fan speed (Via MSI Afterburner), followed by 50%, 51%, 52%, and the last few seconds are at 53%. The fan noise is totally normal at 49% and 53%, but it makes a grinding sound from 50-52%.
Can anyone help me with this problem?
