Hello all! So I picked up my Sicce Syncra 3.0 return pump about a month ago from my lfs. From my research they were some of the best and quietest pumps on the market. On immediate set up there was a significant humm, there was also like a very faint churning noise like as if you were tumbling say some media in a reactor. The noise seems to lessen if I put my hand in front of the intake of the pump. I have purchased a silicone mat to help with vibrations since then but its not a quiet pump by far. Just wondering if others were having the same issues. Thanks all!
