Just commented on your little TV video saying I have one. Turns out I also had this switch! (but the 24 port version) Had it running in my living room for ages until the noise got too much (for me but especially the lady haha) I sent it to electronics heaven in the end (the switch not my girlfriend), worked well though for the time I had it.
I actually put a low profile 120mm fan venting out of the top (I cut an appropriate hole in the plastic top) of this same switch . Used the existing fan power supplies and situated the fan over the mainboard ASIC heatsinks, using the side vents as intakes Works super silently in my home office. Not sure how feasible this solution is if it's in a crowded rack (could probably construct a baffle system to direct the airflow from one side to the other through the 120mm fan)
It is certainly another solution. It always is going to be a problem when you use pro grade kit in a domestic environment because the ultimate goal for the manufacturer is uptime rather than noise. If server rooms were subject to industrial noise regulations we wouldn't be seeing kit with baby scream fans in it.
@@GeorgeChristofi I probably should have tried the two in series solution first before pfaffing about with the 120mm mod. I guess I blindly assumed those little screamers would be noisy no matter what (the gunked up OEM fans certainly were!)
@@dainipeagram4837 I know 3com didn't care because they were destined for server rooms and cupboards, but when you put them in a domestic situation you have to keep the lady of the house happy for many reasons.
@@GeorgeChristofi Did the mod, fans at half speed, but power led is red. I'm guessing the switch is picking up that the fans are not at normal speed? it's a 4200G 24 Port switch

They are pretty good switches with a decent throughput but the noise is silly.

how is the switch going now, about a year on?
Still running fine, no blips or service outages. Not had issues with overheating or any other issues. I'd say it was a success!
@@GeorgeChristofi Brillant! will do the same for my switch, as the noise level did not pass the wife test

@@GeorgeChristofi oh! and also the switch works fine, just the power led is red not green
