Hi
I just bought a GTX 1660 SUPER™ GAMING OC 6G, I first noticed when i was using the aorus auto oc tool, after a while the gpu started making a strange slightly rattlely noise.
i narrowed the issue down to the middle fan, which spins clockwise opposed to the two other fans which spin anti-clockwise. i think the noise is only noticeable if i have afterburner or the aorus engine controlling the fan curve.
