So, I've had this case for about a month right? Airflow is good, very good, has two fans in the front, and one in the back (as well as the fan for the PSU, CPU), so there's a lot of airflow. But, the top fan in the front of the case is vibrating, a lot, granted, I find this to be unacceptable in a new case. I expect this to happen over a couple of years, but a month? I really hope that the bearings are starting to go out, or that the fan is otherwise starting to go out after a month. The product in question is linked here: https://amazon.com/gp/product/B013AY4V4S/ref=od_aui_detailpages00?ie=UTF8&psc=1 I really like this case, it's better than my last one by far, but the fact one of the fans is doing this is driving me nuts. When I listen to music, play games, I can't hear it, but when I don't, I can hear the low hum, especially when I get closer to it, I know it's there. The question is, am I totally boned? Did I get a bad computer case? The reviews were good, the case again, has good airflow. Should I just ignore the hum with headphones and assume that as long as the airflow is good, nothing is wrong? I don't know what to do and I really don't want to have to buy another case, fan, sure. It looks like two 120 mm fans in the front, but I don't know how easily replaceable they are, I've heard nightmares on Amazon on replacing fans for this case. Please advise. Thank you.
