I installed 6 of these fans on my computer (Lian Li 011 Dynamic) because they were affordable branded RGB fans. However, they are definitely not made with the same quality as some other brands. Within 5 months one of the six fans started making a noise that seemed unbalanced to me. I would best describe it as a rattling noise rather than the sound of something rubbing, but it was loud enough to be significantly louder than any other noise my computer makes. I replaced the face and after another 6 months I started doing the same with the second fan. It's been a year since I replaced that second fan and I haven't had any more issues. I suspect it's still a lot cheaper compared to the extreme price of Corsair fans, so overall not a bad buy. Note that they are usually pretty quiet, although I keep them at pretty low speeds considering I only have 9 fans.
