Have any of you seen a test where they test the db from pumps (and who much foaming that’s needed to make it totally quiet)?
Or a review with a compassion to a Hydor?
I'm going to use a Land Rover-71 as a radiator to make the system totally passive (I can almost go passive on my HL120.3, the water temp goes to delta 13°C with ~60Watt load).
And are there any tests with the correlations between volt and flow/pressure/dB on 1046/1048?
