Review on 🌈 Lian Li Bora Digital Series RGB BR Digital-3R S, 120mm Addressable RGB LED PWM Fan Pack - Black Frame, Enhanced Cooling Performance by Brian Campbell

I bought 4 of these for a liquid cooled system. One of them is used as a direct intake fan and the other three are used to extract air through the upper radiator. So far, after 6 months, all 4 have become so loud (whining, rattling, humming) or run very slowly that I had to replace them. The looks are nice, the aluminum cover is nice but they just don't hold up. I have 3 similar brand intake fans that cost less in the front radiator that have had the exact same number of hours/treatments and still work great and are quiet.
