What kind of noise? Fan spinning too fast? Or does it sound like the blades are loose or touching a wire?
If it is the second one, it is possible that dust is the culprit here. Try opening the fan from the shroud and you should see a sticker on one end of the center circular area. Gently peel the sticker and spray a little wd40 inside the hole. Put the sticker back and try testing the fan before reassembling it back to the GPU.
