The noise will be coming from the tool spindle hardly any from the stepper motors/drivers.

To cut down the noise you need a water cooled spindle but they tend to be bigger in relation to the motor supplied with that machine so a water cooled spindle will not fit that machine.
I agree, brushed motors like that are very noisy. Now I've got the water cooled spindle there's no comparison, however the cutting noise is, of course, still a significant contributor to the noise.
