I noticed that the 14cm yates are supposedly quieter than the 12cm yates with more airflow can anyone reign in on this.
They have lower rpm which could explain the quiter dba rating but having the same or greater cfm seems unlikely.
I googled for reviews of the D14SL but didn't come up with anything.
Also how are D12BL yates vs. D12SL yates and S flex?
Was looking toward D12BL yates for horizontal mounting since the SL performed so well in test's here similarly to the S flex's yet much cheaper.
