I am looking for recommendations a quiet fan for a 24v battery bank.  Muffin style preferred. 

I currently use one that would typically be used for a computer, but it is loud. Blows real hard. I put a 24v LED light dimmer on it to try to slow it down, but it doesn't work well. 

Any thoughts?

Thanks!

    Fan noise is related to RPM and CFM ratings... The faster the fan spins, the more noise. You can get Muffin fans with different RPM/CFM ratings. Just find one that is rated lower.

    Here is a Link to a solid & honest company with a number of fans of varying kinds.  (I have no association with All Electronics,   but have dealt with them for several decades,   and they are a very reliable vendor IMO):

    There are not many 24  VDC fans listed there.   You may not need one that runs on 24 VDC.   If you did need a 24 volt fan,  you could probably get  away with wiring two identical fans in series.   Using several fans could help ventilate  a larger area,   and help maintain a consistent battery temperature,   if that is important.

    Would suggest using  a Ball Bearing fan,   for longevity and lowest noise
