My WES 40s have been running on the tank for many years and aren't that noisy running in TSM. Purchased my first MP40 in 2008. For me personally noise is a non-issue regardless since I have a large air pump running 24/7 sitting next to the display. It drives the wooden air diffusers in my old school skimmer which also sits there making the whole scene not only noisy, but rather ugly too . The cooling fans for my diy LED fixtures run most of the day helping to further drown out any sound emanating from the VorTechs. I have no personal experience with the new QD VorTechs, so can't offer any advice there, WarDog has contributed info on those with his thread.

If you want dead quiet, VorTechs may not be the choice for you. I suggested 2xMP40 because with your size tank, you'll have a ton of options & flow while running them at a lower speed. In my experience with my non QD versions, they are barely audible up to about 50%. If you want to make a large wave, then you need to run them in short pulse mode up to almost maximum speed and that will drive you nuts long term, so not a good way to run them constantly. If you run them in TSM limited to 50%, you'll barely know they are running, provided you get them aligned properly.

Here's a link to a post from another thread where I provide a bit of history on my experience with VorTechs.
