Your fan should be a lot noisier at lower speeds than the one I am planning on buying because it hums at lower rpm.
This one:http://www.greenshorticulture.co.uk...108/RUCK-Temperature-Controlled-Fans-1250.asp
150-L has 4 windings and switches between them to change speed.
The two fans would be probably only comparable if yours ran at full power and mine at ca half.
I guess I'll have to just buy it and see/hear.
an expert on fans now?????????
