If it's based only on the fan and not on any color, it's 5/5. Fan works great, exhaust is great. My real problem is the color. I usually blush inside the case. During the holidays my wife insists I change the lighting to reflect the holiday. This year she asked for some green and blue. I've noticed that other case colors drown out the red color of the fan. Green is the worst as it almost turns white again. Blue makes it purple. I have 3 120mm Cooler Master Sickleflow fans on the top of the heatsink and these fans stay red no matter what colors I have inside. I was expecting something like this with this 140mm, but unfortunately didn't get it. I have to give 3/5 because if you don't care what color you are you will still buy Noctua fans. TL;DR Big fan of bad colors when other colors are present
