One reviewer said it is very noisy. Well, I can't hear mine at all. It works very well, and has lots of options. How long will it last? I don't know, but for now it is cooling my Ryzen very well. Are there better pumps? Sure, but at this price, I doubt it. Long term is what will make or break this thing. I do recommend it.Works for me. No leaks. Single speed. Pumps well.I took off a star because of how noisy it is. It's the loudest of all the pumps I've tried so far.This is same pump offered under different vendors: Ciglow, Sanpyl, Aramox. Cheap, plastic copy of EKWB. Get something better for little more.I've been running this in my build farm loop for about two weeks now, and it has been doing a good job.Originally I was running a single CPU block and a 120mm rad, the pump was nice and quiet and had good flow rate. I've since added another CPU block and upgraded the rad to 280mm (so it's now cooling 2x the machines with a lot more liquid mass to move around) and the pump is audibly buzzing, so I'd say it's just a little bit too much for the pump to comfortably handle. Stick to a single block with reasonably sized tubing and you'll do just fine with this little pump.Inlet ports on the top and sides are a nice touch, as well. I've got a reservoir directly attached to the top inlet port, but it's nice to have the option to have the res be remote as well.
