Review on Cooler Master MasterFan MF200R ARGB Lighting Fan by Thomas Taylor

In the first month after I installed the fan, one fan started making a very faint rattle that lasted a second, then disappeared and turned back on. wasn't too loud, not too frequent, and I figured I'd be rejected (and paid) if I rmad it for it. Now I am three months old and the throbbing is constant. Sounds like a bad camp. From time to time the chassis shakes and vibrates (I would forget if he didn't just do it - not even daily). I twirled it around a bit while it was off to see if it made any noise and it does. One of the other two starts knocking very softly, but you don't realize that until you turn off the terrible one. The third fan is fine, but 1 out of 3 after 3 months is not a very good indicator. After 3-1/2 months I am about to replace the fan and the second shows the beginning of it. Questions.
