I am rather ignorant on this topic, so apologise if the question is rather stupid.
I have this fan: https://www.arctic.a...ctic-f8-tc.html installed on the back of my dobson primary mirror. From the specs I can see that it can operate at 12V, 7V, and 5V, reducing the RPM of the fan.
If this fan is attached to a dew controller (e.g. AstroZap 4 channels controller) and this is set to low, will the fan rotation decrease?
The reason why I ask this is because I would like to leave the fan on while observing, but at a reduced speed.
Thanks for your help.
