I just got a current USA 1/15 HP nano chiller for my 30 gallon temperate seahorse tank.
It is quiet but not silent. A quiet fan noise.
It lowered my 30 gallon tank from 78 to 68 degrees no problem.
I have it turned off now (horses haven't arrived yet). I am waiting to get a bigger pump for the chiller, with too low a flow rate the thing cycles on and off too much.
