This was my 2nd dc-lt pump. After 18 months, it's completely dead. The last one started rattling like rocks in a tin can after the interface for the shaft on the impeller elongated and the impeller was hitting the housing as it spun.Unfortunately I'm locked into using this pump until I build a new PC as I'm space constrained in my case.Not worth it for the short lifespan of the pumps.

They claim it's silent....that is incorrect - i can not hear the pump at all, it makes literally no noise at all.This is beyond silent, has also very little amount of vibration and all that at 100%!According to what the label on the pump says, it runs at 3,2Watts of which i was sceptical, after all, my weakest pump has 9Watts.And the label also says 72L/hour.....i assume that is at 100% rpm and a level difference of 1 meter?bcoz it has actually a very good performance even at 50% of speed, it seems it even starts at 40%, very interesting.Just like one of my high performance water pumps, it has to run at 80~100% when the CPU draws more than 200Watts, as seen in the screenshot, i ran it it 250Watts, and the pump at 50% did result in slight thermal throttling, but at 100% rpm there was no thermal throttling at all.The water block on the CPU is the "Heatkiller IV pro" which has a very dense fin design and some of the pumps i have, do not really perform well with it.The radiator i use is a MO-RA3 420, and it take about 5 minutes for this pump to make the water complete a full loop, which is quite awesome, as i intended to run it at low rpm to make the use of the radiator size, so that it can cool the water without the fans - passive cooling with this pump will work excellent.At 100% speed, the pump made it in about 2minutes and 20 seconds through the MO-RA, which is similar to my 9W pump that runs at 50%.This is quite interesting, i need 100% on my old pump to not let the CPU thermal throttle, and with less flow speed the DC-LT 2600 achieves it at 3,2Watts instead of 9 Watts on my old pump.I think the static pressure must be very high on this tiny pump.I was going to make a video on the noise level, but for that, i would have to turn off all of the fans in my PC, even the one in the power supply, just to show that the pump produces literally no noise at all.Since my most silent fans from BeQuiet run apparently at 15dB at minimum speed, and those can be heard, i assume the pump has be literally close to zero dB noise level.Well, that is my first experience with this pump, and by far, my other centrifugal pumps may have higher static pressure, but most of them have a hard time to start at 50%, and this here does 40%.At 50% the pump housing is at about 30~35°C, and at 100% it seems to climb up to ~45°C, which is not bad at all, except i have no housing for the pump that encloses it completely, and teh pump seems to have some holes on the bottom for passive cooling.The top for the pump as seen in the picture is the 'Alphacool 52197' ordered it also from amazon (it comes with 2 bolts that are slightly longer, than the bolts provided with this pump here, both versions of the bolts are good to mount the pump).

I used this pump for around 5 and a half years before I needed to change it.I think it’s good so far.I hope this one lasts another 5 years.

Ho revisionato la pompa del dissipatore CPU che non girava più

Très bonne pompe (très silencieuse) pour un watercooling custom (cpu custom loop)En revanche les câbles sont très fragile à manipuler avec précaution ( vous torsader le fil 3-4 fois et ça se déchire) j’ai du resouder les câbles pour qu’elle fonctionne à nouveau

I figured a premium water pump would be quieter. Probably not a problem if mounted well secured or hidden in a large PC case.
