+2 pts“Damn, I literally got the Airmega 250s yesterday from Amazon and found this exact issue with the fan. I am also debating whether to return it or not (Amazon does not offer to replace it for some reason, only return is possible and price went up today by like $100). In level 1 and 2 speed, all is fine, no vibration at all. Though at level 3, it does vibrate/shake slightly but nothing out of ordinary. I am a bit sensitive to noise so always run it at level 2 max I guess. Do your guys think it will really cause issues in the long-run? The warranty is 3 years. P.S. Just want to avoid the hassle of packing everything up again and maybe get a replacement that has the same issue :/”
