This switch is a great value for a HomeLab rack. However, if you are using this in the same room you are working in the fan is LOUD, and I would recommend a passively cooled switch instead as the fan gets loud!
However, a 5V (not the 12V, it will not work) Noctua fan of NF-A4X20 fan works in this switch as a replacement, you just need to swap some pins around (the ground and 5V wire are switched I think). However, it still made a slight whine (might just be a me thing), so I just didn't use it
However, if you are looking for a cheap Gigabit managed switch, with the ability to go into 'dumb switch's mode this is for you!
