EKWB Alternatives

Alphacool, huge range over the years I think, individual ram chip blocks etc but I could be combining Aquacomputer into the same range in my memory.
Aquacomputer
Watercool Heatkiller, limited range of blocks but very nice ones without breaking the bank.
Bykski, these cover everything including lower power GPUs, more budget friendly.
Barrow, mid range? Not really looked into them.
Singularity, high end premium boutique stuff I think.
Monsoon, fittings + accessories.
Bitspower, fittings + more maybe?
Others I've forgotten...
 
From personal experience: (overall components not just fittings), and only those i would/have use/d in a build

Premium Quality Budget Friendly
Barrow & BarrowCH - OEM of Bitspower
Bykski
Primochill
XSPC
Monsoon
Iceman
Techn
Thermaltake

Premium Quality Reasonable Prices
Aquacomputer
AlphaCool
Watercool
Thermal Grizzly
Koolance
Stealkey Customs
Phanteks

Premium Quality Premium Prices
Singularity
Bitspower
Optimus
Corsair
EKWB - now debatable
HardwareLabs
Lian Li

My go-to/most common brands:
Radiators - HardwareLabs
Pumps - D5 Vario or DDC PWM.. obviously made by Laing but there are knockoffs floating about - usually EKWB, Aquacomputer or Alphacool
Blocks - Various.. but was EKWB. currently TG DD and an Alphacool Core as a backup
Reservoir - Was EKWB, now Alphacool
Fittings - Previously EKWB, now Barrow/Bykski.. tend to stay away from Alphacool fittings and tubing
Tubing - Soft i would go for something like Clearflex or Tygon zmt. Hard i'd use Acrylic/PMMA any brand

Honestly anything that has an actual brand name on it is as good or better than EK. Been playing with a lot of Barrow kit recently as I plan a few projects and it's every bit as good as the (older) EK stuff I have. Got a couple of Bykski GPU blocks as well and they're solid.

And I've yet to be dissuaded from Alphacool radiators.
 
Just upgraded to x870e/7900x from x570e/5900x and I have to admit I will really miss the EK Monoblock I had for the X570. With that said for the new rig I went for the Optimus Foundation CPU water block and it's a work of art. Really impressed with what they did with this so I can recommend them for a CPU block.

I also have XSPC cpu water blocks and reservoirs, no problems and excellent quality
Always used D5 pumps by Alphacool
Radiators by Alphacool
I have a mix of EK and Barrow fittings which are all great.
Currently got Alphacool 7900xtx GPU block which is working brilliantly.
Koolance quick disconnects are the best thing I bought for my external rad setup but expensive.
Optimus Foundation CPU block check out those micro fins. :cool:
 
Thats some great lists here.
I would second the following:
Hardware Labs
Koolance (compression fittings)
Bitspower (especially 45/90 rotary fittings)
Aquacomputer
Corsair (XR rads)
Laing

I think tubing is by far one area that there is a lot more challenges now - difficult to source older brands like Clearflex and Tygon. I'm about to buy few meters of 13/19mm stuff and still haven't decided where and what :D what is Corsair stuff like?

Clear?
Or coloured?
You can actually get good tubing
If you have a local car factors/parts shop
They do all sorts
Clear pvc,epdm,reinforced stuff for higher temperatures/pressure
Silicone in various colours
Wouldn't be the first time I wanted tubing immediately
And popped into my local one

I may end up with clear this time round, but once I got the kid laid out, I will have a think if maybe black is not a better looking way to go.
Did you mean places like Euro CP or more specialist?
I'm not desperate lol so can pre-order ready for the build:)

Ek zmt is very good in matte black
Basically epdm
And pay a bit extra for ek name
Similar with corsair probably someone else makes it
Shoves ek,corsair name on it and adds a premium

I use local independent car factors
Some of their stuff does come from euro car parts
If you want something they don't have in stock
They get same day delivery from ècp if they have it
There's quite a few local car factors near me luckily
Price usually works out cheaper as no ek,corsair etc name shoved
On the tubing too

The other alternative to the EK Zmt is the Alphacool EPDM tubing. I use this in 10/13mm for my rig but what I will say is that the side walls are quite thin and they give up on very tight bends but otherwise it's not too bad.

The ek zmt in 16/11mm is the same very flimsy
Yet the ek zmt in 16/10mm is totally different
Much much better even though it seems like that tiny amount
Wouldn't make much difference

Looking forward to using Alphacool EPDM 16/10mm for my new AM5 build.

Upgrading from the EK ZMT 16/10mm, hopefully not too much difference, I do have some tight bends on my dual GPUs.

Only changing because for the new build I accidently bought as I bought the 16.1/11.1mm instead, then realised too late, so then decided to try something else.
 
I hear you. I have been buying from Alphacool and Optimus in the US (which costs me a fortune in shipping as I am in Europe). EKWB quality was going down the drain for quite some time. The last straw for me was when I tried to undo a velocity 2 waterblock about a week ago. Firstly, it is badly designed. As if it was meant to be installed one time only. It has these hard to see allan key type screws in from the back of the blackplate which are almost as thin as needles. But when I went to under them I found that they were also made from extremely soft material. So one literally fell apart and 2 of the remaining 3 rounded off. I had to drill it out of the motherboard to get the cpu back. Which was annoying as it was a perfectly fine Asus Hero x670E motherboard I was going to give to a friend to use. There have been other issues, like radiators needing gromits and not having them, with the gromit also changing the clearance measurements overall and a bunch of other issues. So I finally gave up with them. I have to say that I have no idea why I used them for so long. Alphacool have been great. Optimus were great too and the product quality is fantastic so far. (CPU block and 4090 Block as well as some other bits and pieces). I like standard parts that don't fall apart. I am always tinkering with 4/5 different machines at a time for benching and modding so it drives me crazy when a company fails to ship, ships something incorrectly or a product is more proporietary than it should be etc etc. But the attachment screw thing. That blew my mind at how badly designed it was.

Bykski have a great range, try to buy most parts for my build using their parts, and usually they come out with GPU blocks faster for ones that are not reference or FE.
No problems with them, although their manuals are a bit hard to decipher at times.

Other than that, I usually just buy Alphacool.

For radiators, Corsair rads are my goto if buying new, if not I buy 2nd hand as it is way cheaper.
 
I had some bad experiences with Corsair. I cant forgive them for their insane RGB ecosystem so perhaps I am prejudiced. One of the pcs I have has 2x480mm rads and a 420.... so all those fans. It is in a corsair 1000D case. So the natural choice was to go with Corsair fans, which mean Corsair RGB... because why not.... OMG, more wiring than Boeing 747. Utter torture. Particularly the way that when you build it all out it needs corsair, core, corsair commander, hub etc etc and nothing about it is particularly obvious. Absolutely hate that brand now because of this.

On a more positive note. I have a lot of monsoon components for fittings. I have found them to be robust and reliable. Alphacool is bulletproof in my opinion. I havent ever had a single component that did not do exactly what is was meant to. I have an old alphacool monsta / monster radiator in a pc that has been going forever and it is awesome. It is as thick as some rads are wide so very limited case wise, but its brilliant.

More recently, and against my better judgement I started flirting with Ali Express..... Huge mistake. I got hit with a scam. I am english but living between 3 homes in 3 countries. There is this thing where you place an order and you see a value in the local currency. So you hit buy. BUT, then the delivery becomes a value in dollars, not local currency. Two thoughts on that. 1. I was stupid and perhaps it was obvious. But it was and is a known scam. So instead of the equivalent of about ten euro delivery, I got hit with 725 odd dollars, for delivery of a 45 euro equivalent order. Stay away from Ali guys.... it will get you in the end. I thought I was way too smart for that and yet it happened.

But, before it all went pear shaped. I did order some fittings from aliexpress. From a company, trading parts as Barrow. They were actually pretty good. No complaints.

The things is, that the more you step outside of the EKWB continuum, the more you realise what a fool you were. There is far better, for far less. I had some real bs with EKWB from time to time. Most notably on that build I mentioned above. I planned that build, with help, using a pretty detailed CAD drawing. But then the radiators turned up and they HAD to have a weird gromit thing installed or they would leak. This was not clear on the measurements and specs. To make it worse, one of them didnt even come with them!. I had to go through a massive debate just to get them to send out replacements. It was ridiculous. Prior to that, my experience with them was great. You could speak to a guy that knew where you were coming from and if necessary, would tell you that you got something wrong, or even better, this thing that you are trying to do?, you should buy this as well. Which is on the face of it an upsell. But that was great! I loved speaking to someone who knew what they were talking about and didnt insult my intelligence with a script because frankly, I do this all the time. I am fine with dumbing it down, if it gets people into watercooling and enthusiast pcs. But it got to the point where they made things so granular at order, and so painful that they become an obstruction. Where you get to the point that its a 2 euro cost on a 800 euro order and it isnt there, just because the company wants another buck. That is just wrong and worse, recognisable gross incompetence you recognise if you ever ran a business.
