GTX 970 STRIX Weird Noise?

[CombustLemons]

So I was messing with the fans in GPU Tweak. I decided hey lets turn them to max and see the temp drop! As I did that I noticed the fans make a weird scratching/screeching noise when on the highest setting. I immediately opened my case with the fans on max to see what was wrong. I used a flash light and looked at the fan and nothing was scratching or rubbing. What should I do? It is in warranty as I got it got this year around Christmas.

Edit: It seems to be gone now. Maybe I am just paranoid.

Fans will never spin anywhere near 100% under normal circumstances, so I would not worry.

Maybe the fans were still new, I have had new fans that made weird noises for a few days and then stopped. But I may have been another component making that noise due to vibrations when your gpu fans reached 100%. Anyway, your fans will never have to reach 100% under normal loads/conditions because the Maxwell GM-204 is very efficient and modern coolers like yours, EVGA's, Gigabyte's and others also are.
Hope I helped
