Alphacool Eisstation 40 DC-LT Pump Top and Reservoir, Pump Not Included

BLUF- Reservior is amazing, dc-lt pump the jury is still out (and hard to find reasonably priced at times)I want to clarify FIRST, this is an amazing small res for itx builds. I managed to fit it perfectly in my Silverstone Raven RVZ 01.The problem I have is the dc-lt pump itself is a little weak, but the noise is my big issue. I used a smaller 73 lph from another product and it worked ok but made noise. The I decided well if I'm going to have noise I'll try the 120 lph version. At a 100 percent dc power is LOUD. Like the reservior is dry or cavitating. It's no though. It's really weird. I may try in another build to see if it get quiet after a few weeks as some had said. I tried loosening it some which did help a little.
