I have all sizes, from the 95w that plugs into the cig lighter no fan and no noise, to th400w that can be plugged in or fard wired, a bit noisy from the fan, to the 3000w that I have hard wired in my big rig, has a fan but not noisy until it has a big load, then the fan will come on and you can hear it then it shuts off.
As for brands I just buy what is on sale.
