Performance – Max & Speed Percentage
Max RPM, CFM, Pressure & Power
The fan’s airflow is low, but this is not the case for static pressure, which is increased.
20 – 100% Fan Speed Percentage
Since most fan control ICs don’t apply precisely the percentage of RPM speed that you want (e.g., 50% PWM for a 2000 RPM fan should be 1000 RPM), I used to find the fan’s maximum speed and then dial directly the fan speeds that corresponded to 10%, 20%, and so on of its maximum rated speed. I decided to stop doing that. So from now on, in all of my fan evaluations, I will dial the corresponding PWM value in 10% steps to also check how accurate its fan controller is and for my noise results to align with the airflow and static pressure results from the Longwin apparatus where I don’t use RPM but PWM control for all testing.

Proprietary connections with need of a special SW (this fan), proprietary fan connections (BQ DR Elite) with special adjusted form factor of the fans (BQ DR Elite, CM MA824 Stealth & Assassin IV) that you cannot even buy from the manufacturer, and you have to look for it on AliExpress… And people think… what an “exclusive solution” …exclusive doesn’t mean something is “cool”, but the exclusion of other options, solutions, and replacements … and people are even willing to pay more for such an “exclusivity” … when the Apple can profit on it, why wouldn’t others try the same recipe.
…sorry for grumbling, but I can help myself 😊, …by the way great review as usual.
I hope that other manufacturer will not “applemimic” themselves and will not jump on the “great ship of exclusivity” and proprietary environment.
True, exclusive parts or connectors are not always good, especially when we are talking about fans. Corsair’s idea on the Link is good, but other brands won’t follow it, so it is only for Corsair products, which are expensive (but of good quality at least).
I think you have an error in your data for the Lian Li TL fan. CFM at 25dBA should be 44.6CFM and not the 57.2 you state and mmAQ should be 1.4 and not 1.62. I checked with the data from here: https://www.cybenetics.com/index.php?option=fans&manfID=79
