Procurve 1810 is silent and quite a decent switch
I've got a 1800-24g at home and it's a solid switch, I'm not sure of all the differences between the 1810 but it looks like the 1800 is quite a bit cheaper on ebay.
The 1810G is just an updated version of the 1800. Also the 1810G has jumbo frames OOTB where as the 1800 requires a frimware update. Other then that they are pretty much the same.
Ha, that sucks, I was going to mention that I got my 1800 for $100, but I figured I'd just let you be happy with your purchase, but now that it's too late for that...
That's odd. Datasheet says no fan. I wouldn't disconnect it though. Why waste that lifetime warranty?
