Richer-R CPU Water Cooling Pump, 3.5m Head, 800L/H Flow, 3000RPM, PC Compatible, Black

its a great little pump that has been running like a champ. im happy with it

Usually pretty quiet but definitely avoid if it's for your main system as it will die after a few months.

Very quiet for 3 months. Then one evening got loud buzzing noise, the next morning it died.

When these fail they make an awful sound, a deep rooted, monotonous rasp that gets louder and louder, I suspect this particular pump is not used to the initial bubbles you get when you first run the loop, completely unavoidable but beware. The first pump failed, the replacement however seems to OK after 2 months of use it is quiet and efficient. Lets see if it outlasts the EKWB pump I purchased as that has been flawless for nearly a year (I am running them both and getting around 4-5 litres per minute flow).

This is a terrible pump and terrible QC. It was ok at first but started making a noise after 2 months. Took it apart, 4 screws... cleaned, it had grease in it. Once this was cleaned it sounded like your typical fish tank pump. So it has grease in, not ideal, it will find it’s way around the loop.There was damage to the impeller,Pulling the impeller out and inspecting behind. there is a spacer washer that sits against plastic on the ceramic rod. Where it had been glued was not even, so the washer was not held straight and could pivot. that might be why it started making noise after a while or maybe the grease just washed away.got in contact with the company who first offered 10% refund.this was not satisfactory.They then offered 30% refund because it had been used for 2 months.So they are happy for me to pay 70% for 2 months use? That doesn’t sound great.I bought another well I was expecting a refund for the first one. i wish i hadn’t now. It did give me an opportunity to take a photo of it before running it and the grease is visible in the new one. Not only that, the new one does not spin as fast on the same settings. 60% would give me 3000RPM on the first one, the second 60% 2600RPM.The pump is all over the place and relies on grease to stay quiet. It’s junk in a pretty case.

The only reason this dropped the 5th star is because the first one burnt out within around 4 hours. The second one however has been connected for a couple of months and is still going strong.If i needed another pump i would buy this again

so I found out where my water leak was coming from on my pc it was the new water pump the casing wasn't made right and not making the seal it's now blown the circuit board so now my pc system is in bits and unusable.Perhaps I just got a badly manufactured pump from a bad batch which is unfortunate because it did seem on paper this was a solid reliable pump which it was not and I've been building water cooling system for years so i'm an experienced pc builder.

Actually a very decent pump clearly labeled out and in does the job

I didn't expect this pump to be that strong. Having 2 waterblocks, 240 mm radiator and 200 ml reservoir connected with 13/10 tube. The jet is literally blows the opposing wall of the reservoir at 100% pwm. The noise is audible at this rate, about 5kHz, I think. However at 60% it is completely quiet. The flow rate is enough for 2 devices cooling, perhaps even excessive. It doesn't vibrate or heat up at all. The long-term performance is, of course, yet to be seen. I'll take one star away for this.

Zur Lautstärke der Pumpe kann ich nichts sagen, da ich so weit gar nicht gekommen bin. Schon beim Einfüllen des Wassers lief es unten am Kabel direkt wieder raus. Der Plexiglasdeckel ist so ungenau gefräst, dass die Dichtung komplett versagt. Das Wasser läuft ins Pumpengehäuse und würde selbst wenn kein Wasser auf leitende Teil im Computer läuft zu einem Kurzschluss führen, da die Elektronik der Pumpe komplett nass war.Wem sein Computer lieb ist, dem rate ich dringend vom Kauf dieser Pumpe ab.
