NF-A14 FLX,NF-A14 ULN
The last test at 12V made Noctua NH-A14 FLX work with it’s maximum performance with airflow level of 100.8 cubic metres per hour at only 1275 revolutions per minute, while Noctua NH-A14 ULN was much slower with only 825 revolutions per minute and airflow level of 64.8 cubic metres per hour. At 12V there was a tiny noise coming from the air passing through the propeller, while there was no noise at all comming from the second model.
"Both of the fans were completely silent to 9V, but Noctua NH-A14 FLX started to produce noise coming from the air passing through the propeller at 12V. Noctua NH-A14 ULN was completely silent even at 12V." (Dobrin Krastev, DVTests.com)
