a truly poor choice, do not recommend such

a 'low flow resistance' rad (presumably single row and low fin density) in a noise sensitive app needs a low speed fan
2800 RPM is not low
My choice was based on the static pressure of the fan and the fact that there is no motor hum when using a fan controller. I do not plan on running this fan at full speed. I would assume that at 7V-9V this thing is closer to 30db than 40db.

Also, it is my understanding that the PA series has improved upon the HE tremeandously for low speed fans BUT they higher speed fans still have a performance lead.

I have not actually ordered them but I thought that this would work excellent with a PA120.3 plus shroud.

Do you see something inherently wrong with my logic here? Please let me know as I am makign a purchase in the next day or two.
