Looking for the quietest all metal hotend setup.

Looking for the quietest all metal hotend setup. Ultimately I think it comes down to the fan size. Have been looking at the E3D lineup and at the Deltaprinter Mini as well as Ubis 13s. This is going on a machine that is quite silent otherwise and I really want to complete the package with a nice quiet hotend. My current setup uses a Ceramic Ubis with a 40mm fan blowing on part of it. While it works fine I don’t want it near my plastic effector.

Would love to hear you guys’ comments/suggestions

I would suggest that you replace the hotend fan with overpowered blowers that you run at undervoltage to get it to be really silent.
