Its speed and pressure labels are swapped between the two fans and are not used.9Reviewenostech.com/be-quiet-dark-rock-pro-6-review-flagship-cooling-solutionRead 14 October 2026The 135 mm fan is rated 1900 rpm, 76.59 CFM and 2.25 mmH2O. The 120 mm fan is rated 2000 rpm and 2.5 mmH2O. The text gives 89.95 for the 120 mm fan with the unit CFM, which is the m3/h figure in the maker's table, and is not used.
