Thanks. I saw the 2808. Do you know of any with fan(s) that is probably the most quiet?

Yeah, might be more in the pipe dream category.  I have full L3 Cisco/Linksys SG300-20 for my home lab for the same criteria you gave (L3, and no fans).  That was really the only one I could find at the time.  And most with fans will be disappointingly loud.  Just a byproduct of throwing in a 1/2" fan and trying to move x amount of air.

Please share if you eventually find one.

Thanks for the share...I'll have to check it out. I heard Juniper offers good layer 3 gigabit switches that's fan-less. HP had a good one but it was 10/100...come on Dell! Its 2013 already :)

I have the HPE 1920S 24G switch that it is Layer 2 and Layer 3, fanless and 25cm depth.

Dell EMC N1124T-ON switch. It provides both Layer 2 and Layer 3 functionality, is completely silent (fanless), has a depth of approximately 25 cm, and includes 24 x 1GbE RJ45 ports and 4 x 10GbE SFP+ ports.
