Review on 💨 Cooler Master MasterFan MF120R ARGB 120mm 3 Pack Fan: RGB LEDs, Rubber Pads, PWM Control for PCs – R4-120R-203C-R1 by Michael Keitt

Within the first month after I installed the fan, one fan started making a very faint rattle that lasted a second, then disappeared and started again. Not too loud, not too frequent, and I figured I'd be turned down (and paid) if I took it for that. 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.
