Dos buenas noticias para los que están adquiriendo etapas pro baratas.

La DSP Inuke además de incorporar DSP como plus parece ser más silenciosa que las de la serie EP:

the DSP3000 is just borderline on tolerable to me with stock fan. It spins up like a tornado when running hard - but if you are running it hard you'll NEVER hear that fan over the audio levels it's cranking out, it idles back down quick, the only time it's really obnoxious is between songs that aren't crossfaded if you have the volume cranked. I haven't felt the absolute need to mod the fan yet, like I did on the EP4000.
Aún así, como todavía hace ruido tiene el plus de que sus ventiladores son estándares de 12V de PC (no como los de 24V de las EP)., luego realizar un cambio por unos baratos de silenciosos estará chupado:

By the way - the Inuke DSP 3000 uses a standard 80mm 12 volt .4 amp fan. So finding a replacement will be easy. Just browse over one of the dozens of best silent 80mm fan in every single PC forum and you'll have some good suggestions.

The EP4000 by contrast uses a 24 volt fan, and it's a bit more difficult to guess on a unknown model.
