Fan selection depends on a LOT of different factors.... rated fan speed vs. voltage applied, CFM vs fan speed, dB vs. speed vs. CFM. Min/Max current required, dimensions including thickness, type of bearing system, etc, etc... Ambient temperature.... Inlet restrictions, outlet restrictions, internal obstructive flow.... thermal loading, etc etc... Isolation mounts are simply one consideration.
BUT, anyone considering the replacement of stock fans should insure that the replacement part supplies the same or more air volume at each speed level.... unless you're planning to do a detailed study of your operating condition to make sure the air delivered will accomplish the thermal control required. ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 2/11/2017 10:27 AM, Harry Yingst via Elecraft wrote: > A few years ago I replaced the stock fans on my K3 with the Noctua NF-A6x25 > FLX fans and rubber mounts.
