Aside from CFM rating, the static pressure difference is massive. I am not happy that AIO fans only list their CFM and RPM rating, but not their static pressure rating. The original black LLs have a low CFM and a static pressure of about 1.4. The NEW white ones have a shocking 60+ CFM and a static pressure rating that puts them above the HD120s.
Below is a list of fans. The ones near the top have a high CFM and static pressure rating along with RPM.
In terms of fan performance hierarchy, the best PMW fans I know from Corsair are:
ML Pro Series (Includes LED Counterparts) LL RGB White Edition HD RGB ML Pro RGB LL FGB Black
The rank is weird how the Maglevs are high up with static pressure of 4.2mm and a CFM of 75. The upsetting part is how the ML RGB versions have a CFM of 47 and static pressure of 1.7mm and lower RPM than its LED version. It costs more money and is crippled and compared to their single-color version. This may be another topic, but fans using the same bearings and fan blade designs should have the RPM ranges for same specs. The specs RGB version of ML should be equal to that of LED versions with the difference being the colors.
The coolest idea Corsair could have is if Corsair made a fan combining the motor of a LED Maglev (the highest performance one) and have the LEDs of a HD120 or LL(the most beautiful ones depending if you want more addressable zones of 2 loops to customize ). We would have the ultimate fan and colors without compromising.
