What is the difference aside from color on these fans
Phobya NB-eLoop 1600rpm Bionic 120mm Case Fan
and
Noiseblocker NB-eLoop Series B12-PS 120mm PWM Bionic Loop Rotor Fan, 1500rpm, 21 dBA
First one listed is 1600 RPM whereas second one is 1500 RPM and is rated at a higher airflow 61.21 CFM vs 58.09 CFM and noise level 22.5 dB vs 21.2 dB. Another thing to consider is that translucent plastic fans like this one tend to be made of plastics that are less solid (or softer) plastics that tend to vibrate more when spinning at the same speed as a fan made from harder plastic, and therefore create more noise.
