I never liked their skin tone colors. If i need a fan i always go to Noiseblocker first. Never been disappointed in years and i'm only using their lowest end range of fans. They are nice looking, good airflow, silent and easy for maintenance (they are sleeve bearing after all).
I've had 2 Noctua fans (with a Noctua CPU cooler) in my hands when i was assembling the system for a friend and they weren't silent at all and one was clicking in intervals while spinning. Not exactly impressive.
