Its rotational speed ranges from 350 to 1,900 rpm, with a maximum noise level of 27 dBA (31 dBA for reverse blades), airflow of up to 62 CFM (54.3 CFM for reverse blades), and a maximum static pressure of 2.9 mmH2O (2.83 mmH2O for reverse blades).

The 140mm model measures 144x140x28mm, also employs an FDB and PBT blades. Its rotational speed ranges from 400 to 1,600 rpm (350 to 1,600 rpm for reverse blades), with a maximum noise level of 28.5 dBA (29.4 dBA for reverse blades), airflow of up to 68.1 CFM (64 CFM for reverse blades), and a maximum static pressure of 3.5 mmH2O (3.1 mmH2O for reverse blades).

Both models feature a unique 7-pin connector and require a dedicated controller for operation. Stand-alone products are primarily for expansion purposes. While pricing is a little unclear, ti seems the LCD fans cost $55 each.
