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

This is a very strong pump and its beautiful. I designed a custom loop that goes through two 44mm width 420mm Alphacool Nexxos V.2 radiators, a Quantum Momentum^2 Z690 Hero mono-block, and a EK-Quantum Vector FTW3 RTX 3080/3090 D-RGB - Nickel + Plexi GPU block. Though the loop order is scientifically insignificant, I wanted the coolant to hit the CPU first, then be cooled, then hit the GPU, then be cooled on its way back to the pump. This required slightly longer runs than the boring, go straight from the pump to the GPU block, to the monoblock, to the rads. From my years of past experience as a wildland firefighter and a plumber in my younger days, I like the plumbing aspect. However, I knew that the longer the runs, and the more fittings used, the more drag the plumbing would have and therefore the more pressure would be needed, not to mention the coolant had to make it through two big radiators. I did not want to sacrifice volume for pressure by going to a DDC, so I needed a pump with both good head pressure and volume ratings. The D5 was the obvious choice. Though my case and fans (that I love) and RGB controllers were all Corsair, the XD5 just did not match up statistically though it would have showed up in iCUE and I do like the square design, and it was $30 cheaper. Upon installation there was a major issue that you can see in the video. My pump seemed super weak, and I hesitantly theorized a vapor lock issue over a weak pump. But after tipping the system several times, no air was bubbling out. Something was wrong. First I tried disconnecting a tube and siphoning some coolant through most of the system to see if I could break the vapor lock but only ended up with a bad taste of coolant (a little I washed out thoroughly ha!) and the same problem when I reassembled. So, reluctantly I drained the system and pulled the pump to see what mechanical issue might be going on. When I pulled the pump apart, everything looked fine inside but when I grabbed the reservoir, by chance I noticed something was off. At a certain angle light was barely coming through the metal inlet tube I had screwed into the reservoir lid to avoid splashing. I looked down it and saw that there was something in there. I poked it out with a small screwdriver. Turns out two plastic washers were lodged in the inlet tube. I remember the tube had come rumbling abound in a bag of parts with screws, washers, a plastic vortex tube, etc. Somehow they must have lodged in the tube and were the perfect outside diameter to match the inside diameter of the tube.I attached a photo of this as well. I then reassembled and tested the pump outside the case (lesson learned) and found it to be pumping great. I then put it back in the loop and this pump now kicked arse. It pumps so hard, despite the big loop, that it would drain the reservoir in about 5 seconds while bleeding. Massive difference. So, the moral of the story is to check your pump before install due to poor packaging of parts, and that this pump is insanely good when it’s not handicapped. Definitely BUY THIS PUMP, IT’S POWERFUL AND EASY ON THE EYES. My system is running super cool. Even my power hungry FTW3 stays low to mid 30s at idle.

Very quiet, but it could be an inconsistency among other customers. I've never needed to use any extra dampening. If not for the fans, you'd never be able to tell if my pc is running. It was a bit large for my current build butting into the gpu I have over reaching to the radiator in front so I had to downsize the reservoir. Turns out the whole thing is simple design, which allowed me to twist the cylinder right off and swap that out with Thermaltake's. The other pump I used prior, which is also pretty good, but the pump simply seemed a bit small with how much water and rads I wanted to go through. So glad I upgraded here. Noise level: Not even a whisper of any noise just outside the glass case! Ease of installation: A simple design that features different power options to plug into (Molex, Sata PCIe). The motor itself is quite compact.

Works great, no problems so far.

If you're looking for a high-quality liquid-cooling pump at a decent price, you've found it! I've been running it for 6 months and it has performed flawlessly. It is pretty big and may not fit in some mid-tower cases so check your measurements carefully if you need it to fit inside your case. It is very quiet. I have to look for the movement of liquid in the reservoir to even know that it is running. Installation wasn't too difficult. You may need to drill some holes in your case for mounting (a template is provided). I feel like it will give me many years of reliable service.

Don't get me wrong.. It's a gorgeous setup but very expensive. I have a 7 year old 500 liter per hr. EK pump/res combo that still functions but wanted a better flow rate for my new build. These D5 pumps are 3x as powerful. Very noticeable difference! This clears out air bubbles with ease where as before I would have to tilt my case around and help the pump out. I feel like with anything EK, you end up paying for looks as much as quality. But my whole loop is EK so godda do it!

Got this for my first cooling loop build and I'm pretty happy with it. It's very quiet and as you can see from the picture, it's RGB is pretty bright and illuminates the reservoir to the top. This thing is beefier than I was expecting and it's pretty solid and seems well made. There are 3 inlet ports on the top, and 2 inlet ports near the base and one output port. Make sure before you plan your loop that you know which port is the outlet or you'll be making some changes like I did. when filling your loop, just make sure not to run the pump dry. I didn't have this issue, but every video I see on the matter stresses the importance of this. Overall, I am happy with this pump/rez combo from EKWB.

I unfortunately had a poor seal in my pump/res causing a leak. Titan Rig was very quick to help out and they sent out new o rings because it would be faster than waiting to return and replace the unit. Unfortunate that EK does have some quality control issues, but Titan Rig was quick to help out when they could have easily said “well that sucks”.

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.

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

Packaging très propre , simple a monter .

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!
