Review: Best value to quality fans I know of - Great fans, quiet and very nice performance, though one did arrive with broken RGB. I have another 3 120mm versions installed in another PC and never had any issues with those, and the replacement fan works fine so I still feel good recommending these to anybody
Review: Best fan's I ever had - Amazing fan's, a little expensive but the build quality makes up for that. Noise is okay and it kicks out alot of air. PC running 5°C cooler now after replacing my old cheap fans. RGB look's amazing. 10/10
