Those metal pins are for balancing the impeller. i have 2 pumps. A Laing D4 (old one 2007 or older) and a AlphaCool branded one, and both have have a couple of pins of varying height (thus weight).
yes the metal is throwing the pump out of balance, you may not see it vibrate but it is indeed vibrating, your option to open the area a little simply opened the tolerances between the rezzie and pump so that now it isn't hitting.

@@calvinminer4365 just saw this so I thought I'd answer I know this was posted a year ago. Here is some suggestions for the future Watercool.de (aka heatkiller) , alphacool, aquacomputer, and hardware labs and some magicool products. Most of the brands that have confidence in their products are fairly transparent. For example hardware labs gives info about pressure testing as well as at fairly high deltas how much energy dissipation you could expect to get from their rads. Believe it or not that info is actually fairly useful though again they rate it at a very high delta. I can't fault them for it but atleast they do it. Watercool.de (heatkiller) gives pressure testing specs and has confidence in their blocks. They are some of the better machined blocks and for reasonable prices only gripe in on some portions of the block the surface finish could be improved but they are very good blocks. Alphacool has some good stuff and some meh level stuff but they do give proper information about how they test their products. Magicool is actually a OEM for a few companies actually one of them I mentioned has used them in the past. But magicool does make fairly good radiators for certain uses. They also pressure test to some of the highest pressures in the industry on SOME not all of their radiators they have a few different series and they are not all pressure tested to the same degree. However I would ague they are one of the more transparent companies. Barrow also with some things is a good alternative as well. Assuming the price is right EK refuses to give really any information on their products and they will happily void your warranty. For example they make blocks with some questionable acrylic and they don't provide torque specs to prevent damage. Then they will void your warranty for improper torque being applied via fastener that they don't provide a spec on. In some places this would be illegal but you would have to argue this in court. One of the best examples of this on their blocks is the supremacy MX blocks there is a version with a waffle like top that's not even solid acrylic. It has cracked on tons and tons of people from not even cranking down to hard on the fittings actually if your tubing is a bit stiff just trying to get the loop plumbed up will be enough to crack it. EK also has a history of making crappy blocks on occasion in the past few years then totally revamping the product cause the performance was shit then telling the people who bought the original version we won't help you other then we will give you a few Percent off the purchase of the vastly improved actually useable version. This has happened a few times over the years now or stuff similar with them. All in all the companies that are trustworthy tend to backup their products with data and post it in plain sight on their website. The companies that tend to be untrustworthy don't talk about pressure testing , or any other specifications. I don't have to name all the names of brands that have those issues. You can just see it for yourself when you look at their product pages and look into those products. I will give EK credit on 2 products. Their pressure tester kit is one of the better ones on the market though the hand pump it comes with leaves a lot to be desired and the price at 40 is a bit steep for what you get if the kit was 30 I'd have 0 complaints. Also their rubber ZMT tubing is actually good from the standpoint of watercooling specific tubing products however it's more flexible but not quite up to par in other ways with automotive trans oil cooler lines and double wall fuel line. Are often made of the same material. Good for different uses. I prefer using the double wall fuel line and trans oil cooler line (with corded sleeve between the 2 walls) for water chillers esp. as these tubes are quite well insulated with 2 seperated layers of rubber. That being said they still get frost/condensate on them eventually
@@Onewolfoc This is very good information. Could you link examples of the automotive hoses that you use. Do these work well with all cooling liquids and are they inert to chemicals?
the balancing is used for more viscous fluids being pumped, otherwise its a problem with material as thin as water cause it will form its own self correcting bearing, EK has a habit of more money = better not what is the best solution for the problem we are solving
My XSPC D5 Vario has those weights inside the impeller for balancing, but my Xylem D5 PWM pump doesn't have any balancing inside, I am assuming they do that only if its needed for that specific impeller and that specific pump and they may not have gotten it 100% perfect on that one. Love the vids man!
Great stuff man, I love your work. Glad everything worked out with the pump and it's a great idea to show people that you are always changing things to fit in the real world. Keep the vids flowing!!!
FOGGY CONTACTS what baffles me is that a good name brand as ekwb would have gave me this noise issue. but at the same time that’s why I try to get different pumps from different brands to get this type of problems before I release something and adapt
@@radikult-custom I see that issue before. A lot in fact. They let the pump run dry and burned the ceramic ball off causing the impeller to contact the body. I also see balanced weight fall off causing the impeller wobble that burned the ceramic also. But that is much lower number compare to the first case.
I recently bought a EK FLT with D5 and it makes a grinding noise at startup or any speed under 50% I think the impeller balance is off or maybe the res housing is off. I’m ordering a Aqua Computer D5 to replace pump hope it fits the EK res mount bracket with the smart panel on top of the pump.
It’s really hard to tell which part is “faulty” maybe the pump housing is a hair off and that’s why it makes that sound. Or the impeller is a bit out of balance. As you can see in this video I try multiple brands and I could only get the noise from the EKWB pump and by close inspection I notice the pins inside the impeller had like “extra” material at the top while all other impeller didn’t.
@@radikult-custom have you tested the fitment of a Aqua Computer NEXT D5 pump in a EK FLT res. I’m a little worried the top/screen attachment might be a little to big for the res mounting plate.
Hello, I have a vpp655 vario since 2006 working. I had a problem with the rotor. It seems that the area where the ceramic sphere rests broke due to fatigue, I suppose. I bought a new rotor on Aliexpress and the exact same thing happened to me that happened to your client. The rotor collided with the block (alphacool HF d5). The decision I made was simple. Replace the O-ring with one that further separates the pump from the block. I think it would be a simpler solution for your reservoirs. All the best
Hi 👋, probably the impeller is a bit out of balance and that’s why it’s making some noise inside the reservoir. Unfortunately there is no easy way to balance an impeller, but putting a thicker oring to separate the pump a bit is a good idea. 👍 I have already change and updated the pump inlets on the reservoir to prevent any of the issues with impellers hitting the reservoirs. Thanks for the tip maybe someone can read this and help them
@@radikult-custom That's what I thought when I put it together and indeed when I raise the revolutions to more than 3/5 the rotor vibrates. I'm going to buy a new block and pump. I don't know whether to apex or go to what I know works and take a VPP655 again that has been working for many years, but this time I will take the PWM version. I think it is not worth buying an Apex because it no longer has the ceramic dial as I have read. Great job you do, I always wanted to make my own blocks, but I never had the money to buy a decent CNC. All the best

Disliked for misleading title, this video isn't about a decision between D5 *OR* 655 at all, which is because usually any 655 pumps just *ARE* D5 pumps. Which is why this title made me curious. And then you were talking about a reservoir all the time. Dude!

You know all those are D5 pumps right... They all made by the same company.
Disliked for misleading title, this video isn't about a decision between D5 *OR* 655 at all, which is because usually any 655 pumps just *ARE* D5 pumps. Which is why this title made me curious. And then you were talking about a reservoir all the time. Dude!
That's what I thought when I put it together and indeed when I raise the revolutions to more than 3/5 the rotor vibrates. I'm going to buy a new block and pump. I don't know whether to apex or go to what I know works and take a VPP655 again that has been working for many years, but this time I will take the PWM version. I think it is not worth buying an Apex because it no longer has the ceramic dial as I have read. Great job you do, I always wanted to make my own blocks, but I never had the money to buy a decent CNC. All the best 😊
Was here
Failed to explain anything about the pumps and their differences. It was just a video about a problem you encountered with a pump. That is fine for what it is. But the title is completely deceiving and it was a waste of my time.
