You might fins what I've posted on this thread (towards the end) very relavant:

Have you considered a water cooled spindle

They come in ER16 size you need a VFD to use & control the speed OK in Mach3

They run from 8 to 24K

As they use water for cooling they should be pretty quiet as it's the air cooling fan that makes the noise in routers
