Yes I've owned a few chillers and Oceanic is by far the quietest on the market (I hardly notice it when the compressor / fan are running)... Note: The exhaust fan blows out allot of heat. You could probably use this as a heater during the winter months... Currently I'm using my 1HP chiller for a 500gal fish tank but I hooked it up to my computer prior to see how it would work... It worked great but I wasn’t using the rated pump so the water started to freeze after a few minutes (I wasn’t about to use my aquarium pump for this test)... Unfortunately I really can’t provide you with allot of data but I was running Prime95 (58C) when I tested this chiller and within minutes the temps started to drop dramatically and I had condensation on the lines after about 2 minutes.. IMO this is not a good option if you’re going to keep it in a small room or office because of the heat… Ooo and this thing weighs about 32kgs (living areas are okay). The lower the HP the quieter the system will be, and I’m sure the ½ HP has plenty of power and it’s designed for continues cooling… Hope this helps a little…
