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 Jonathan Jensen

These were probably the nicest fans I've ever bought. Aluminum frame, great RGB lighting. However, the only thing they fail at is being a fan. They are good in some orientations but if you place their hub as top exhaust fans you will hear a very noticeable knock/pull sound. I order 2 sets of these fans and all 6 had the same issue. Contacted the manufacturer and they sent me 3 more, 2 out of 3 had the same sound. I replaced some cheap old fans that were sitting idle and the problem was solved. Too bad, such cool fans
