EKWB EK-Quantum Kinetic TBE 200 D5 PWM Pump-Reservoir Combo, D-RGB, Acetal

Es ist meine erste Pumpe und ich bin top zufrieden, schöne rgb Beleuchtung allerdings ist der Schriftzug nicht extra beleuchtet.

Now I know these pumps are not made by EKWB (EK Water Blocks) themselves but they have a resposibility to address any issues that may develop over time (at least within 2 years under EU law) should there be a manufacturing problem - and let me tell you right off the bat that if you have a problem, they will flat out deny that there's anything wrong and it's all within "their" standards and will refuse to do anything about it. Don't be fooled by their reassuring fluffy customer support mission statement that is intended to give you false sense of security. I've had this unit for just about 1.5 years and during that time I've heard all sorts of noises coming out of it, one being an insanely loud grinding noise, to just plain loud at anything over 3000RPM - if it sat or was connected to the PC case - now in my ignorance of anything actually being wrong I was able to mitigate these problems by resting the unit on soft packaging foam and limiting it's Max speed to just under 2800RPM Problem solved! Or so I thought, 1.5 years in and the thing wouldn't start causing my graphics card to over heat and force me to do a hard shut down. This is when I realised the pump wasn't working and wouldn't start. Got in touch with EKWB customer support to RMA the thing, as it's still under warranty under EU law (2 years) And they said that all I needed to do was open up the pump and clean it. Which I did, and I found tons of this black plastic residue coating the internal structure of the impeller and bearing seat where it's rubbing, and sure enough it worked again, all good so far - but then I noticed that the impeller part of the unit wasn't really looking very good eg. what I have shown in the photos as internal plastic chipping. wearing of the seat where the bearing makes contact, horrible moulding, external edge chipping, a dent in the outer shell and rust! I couldn't believe my eyes and thought there's got to be something wrong here, and there is - it's called balancing, these impellers have to be carefully balanced to take out any wobble it might have at high speed and if it's even slightly out your going to get vibrations which lead to wear and noise, ultimately after further use the thing will destroy itself! Easy fix you might say, just swap out the impeller for a new one? Nope! EKWB (EK Water Blocks) say "Impellers are not available as separate spare parts, and we do not replace them individually." and "There is no functional fault that would qualify this pump for an RMA. This concludes our position on the matter" LOL - It's like the dumbest response to a simple fix I've ever got from anyone - all they had to do was contact their suppliers - Xylem - in this case and send out a replacement part - no need for RMA. Anyway, if you've read this far, my word of caution is, if you have any symptoms like loud crunching noises or unbearable vibration above 2800 RPM you may well have a dodgy impeller, open the unit and visually inspect the impeller, if it doesn't look right send the unit back immediately! - personally I wouldn't buy from EKWB (EK Water Blocks) as they are just completely useless as a company, have no quality control standards at all, and they will leave you high and dry on your own. Good luck!

Works great, no problems so far.

Quite running. Could use a better manual it took me a while to figure out the installation procedure. Now that I know how to do it it would not take that long. One thing I could not find was what cooling liquid can you use. I use Thermaltake Coolant 1000 green. Will see how well it works.

Bought to replace an old leaking failed DDC water pump. This pump is quiet and provides ample power to push fluid through a loop consisting of two radiators, a pair of parallel GPU water blocks, and a CPU water block. I like the LEDs, though the plug is a little wide to fit in my ARGB splitter so I had to trim down the size of the plugs and there are visible hot spots in the LED ring.
