I have been using air cooled spindle for some years now, though it is only 1.5kW, but it is that noisy before cutting starts. If it must be replaced I'll buy another air cooled spindle, that's for sure.
Thanks, it would certainly make things easier to go with air-cooled. I have a small room set aside for the CNC to go in anyway, so that will probably be the best way to deal with overall noise.

You mention that you have a brushless spindle? The one I'm looking at has brushes as far as I know:

I can't find brushless spindles above 1kw. Where did you get yours?
