What did Alphacool do here? Water Block Roundup 2023

[@DerangedCoconut808]

I always find EK to be the SnapOn of the watercooling industry. Big money for identical or comparable performance to lower priced products. you are mostly paying for the name just like SnapOn or Matco tools. (old mechanic here, thats the closest analogy i can relate to)

[@LawrenceTimme]

It would be interesting to test older water block generations to see the progress. I still use my ek supremacy evo

I use EK-Supremacy EVO too and I wish to know if it's worth upgrading.

[@spaghettilocomotive]

I recently swapped out my Supremacy Evo for the new velocity2+direct die conversion kit for my 12900k, but the block or direct die part was pure garbage, the old supremacy evo cooled better than after delidding and liquid metal. Safe to say I wish I could turn back time and just keep it stock with the old block.

@der8auer EN Pleassse do it. I know in a vacuum choosing LTT was the right business decision (assuming they wouldn't mistest it and slander it) but I would love to see Roman's opinion as an engineer. Neither Steve from GN, Jayz2cents, or any other youtube have the machining experience Roman has and that should be one of the main things to be evaluated. Aesthetic finish, fluid dynamics, craftsmanship, performance, and value. I have no clue what gives Linus the right to say it's overpriced when he knows nothing about labor and materials costs in Europe. Roman has first hand experience running a machine shop and would have the best opinion in the tech space on whether the product is priced competitively in an objective sense. I know it will never have 'value' when it's competitors have 1/8 the price, but what manufacturing costs are all things considered and what the profit margins likely are. If I can pay my local machine shop to make the same/similar for me at a more competitive price then they might have a problem.

Agreed. Although, as unfortunate as the situation was, it brought a lot of things to the surface along with the Lab's jabs at HUB and GN regarding data collection stuff.

[@marinipersonal]

EK is not too bad. Performance average, design is good, but is waaaaaay overpriced, also quality control is poor. Shipping active backplate with longer screws that wouldn’t fit as desired, cracking the bridge between the blocks (stress), distro with over tighten or not tighten enough, same issue for GPU blocks. Let’s not forget the DOA RGB strips or the flipped jet plates. Apart from that, is fine. 😂

I just switched from EK to a Heatkiller block for my x570/5900X, and it was used. I had to take it apart, and clean it but it dropped my temps by nearly 10c compared to the EK. Increased clocks on all cores, breaking the 5Ghz barrier I had before, to 5.12Ghz, and near or over 5 on every other core. It's sharing a single 240mm x 60mm rad with a 3090.

[@robertbrundige3998]

Excellent review. Very surprised by EK's performance. I am going to have to reevaluate my cooling decisions. Thank you

[@rekareaper]

I really wish you would test with higher pump speeds as well. I understand why you don’t, but it would be interesting to see the differences.

[@GhostPsi69]

Theoretical performance vs actual real life performance, also doing max pump speed would allow manafacturers to cheat on flowrate in the blocks.

[@rekareaper]

@@GhostPsi69 it is actual real life performance for me. I have two loops that I sometimes combine. Each is a MORA3 with an EK Dual D5 pump top that all run at 100%. It isn’t cheating on flowrate to have a block designed for high pressure and high flow, as that’s how you’re going to get the best heat dissipation.

[@jjlw2378]

I run my pump 100% all of the time. My computer sits a good distance from me and I can't hear it at all. I've never not run a pump at 100%.

[@fermitupoupon1754]

@@GhostPsi69 how is it cheating though? I mean I vary my pump speed because I want to achieve a certain dT across the radiator, but other than that I see no real reason to do so. If you mount a D5 properly, you're not going to hear it, regardless of pump RPM. My old D5 didn't even have speed control at all, it always ran at full speed. As long as you keep the same pump speed between different blocks in the test, it effectively shouldn't matter what speed your pump is running. Unless a specific block is really designed for slow flow, but then again why would it be, as that just isn't the efficient way to go about it.

[@Gobbbbb]

Would just like to say thank you for making English videos in addition to the German ones, it really is appreciated and I hope one day to learn German.

[@alexanderm2702]

I would like to see a test with a vapor chamber between the CPU and the block. I've looked into doing it myself but the power rating on the ones that would fit seem to max out at 150W. My theory on why the Alphacool block is so good: the sideways slots offer an easier path to get rid of water that has already contacted copper and warmed up. That allows higher flow rate of fresh cool water. It also creates turbulence in the water and also creates a bit more surface area.

[@skaikey]

This was very good, thank you.

[@jirismidak2001]

Hello, IT? Well, I actually own the Alphacool CORE 1 block, it sits on 14th Gen i9 in Z790 motherboad. And all I can say is, its awsome! It really is! It performs great, keeping the CPU around 60C when playing MSFS2020, which is the most demanding application I am currently using. To be fair, I must say that there is also an Alphacool GPU block on a 3090. And I have a very custom loop with 2 huge 40mm 360 radiators with legendary German Noiseblocker FANs and almost 4 liters of water in the whole loop, pumped with DDC 1T Plus pump. So, plenty of liquid + plenty of cooling capacity = cool and quite components. Great video as usual! Thank you!

[@Gregregorovich]

That Barrow RGB header is compatible with standard 5V ARGB, if you make (or buy, if they exist) an adapter; looking along the wire (with the wire closer to your eye than the connector), with the pins at the bottom of the plug with the snapped/cut off plastic tabs below it, it maps to left to right 5V, Data, (no gap), Ground.

[@СусаннаСергеевна]

My favourite block is the Barrow CPU-pump-reservoir combo. Elegant way to fit watercooling into SFF. I’ve also asked why they use a fan cable for their LEDs. The answer, it seems, is simply “it’s a better connector”. Which is true, anything would be better than the actual LED connector, but it feels like it’s only an excuse to sell adapter cables.

[@scottcondie1363]

The core 1 looks great and performs very well. I still use an alphacool nexxos xp that I modified to fit my 10850K but its tempting to upgrade. It would be nice to have good mounting pressure as my mounting bracket has a single bolt that presses down in the centre of the block.

[@1984TarpeN]

Really nice videos to watch, I just bought an AMD 7900x3d and bought myself a Corsair Hydro X Series XC8 RGB PRO JTC Edition because it was so much cheaper than buying an EK block. and am really happy with the result. Corsair $110 vs EK $220 😃

[@Cinnabuns2009]

I went with HeatKiller IV because it has a bracket that I (as a machinist) can change out and make to fit any hole pattern on any board. Also, it doesn't need mounted offset because the inlet is toward the chiplet side on AMD so the chiplets get the cold side and the SOC gets the outlet. Very nice feature.

[@bluegizmo1983]

I'm running a cheap 360 AIO and it keeps my 13900K from thermal throttling. I hit a max temp in the upper 80's at all stock settings, just undervolted, which doesn't lose any performance, it actually gained performance vs not undervolting.

[@420bobby69]

@@bluegizmo1983 funny you mention that, undervolting dawned on me last night as a pretty obvious thing to do. how far did you push the negative offset on yours?

[@bluegizmo1983]

@bobbyp6592 I didn't use a negative voltage offset, as I followed a guide that talks about how its better these days with modern CPU's to use Load Line Calibration to achieve an undervolt. Google "Asus Maximus Z790 Extreme and Intel i9-13900k - A tuning guide for beginners." It's a long interesting read about why this way is better, but to jump right to the information, you want the second post, then scroll down to "So let's start tuning the beast !". Basically it amounts to setting the DC_LL = 1.02 and AC_LL = 0.2, that's it, it's undervolted. You can fine tune it more from there but as it says in the forum post, those numbers should be stable for just about all 13900K's

[@420bobby69]

@@bluegizmo1983 LOL dude im literally reading guides about Load Line Calibration right now wondering if that's a way to optimize the undervolt for stability. I remembered der8auer explaining that setting in his 8700k OC video years ago, and how it affected the way the CPU handles 'voltage droops' or something. You have incredible timing, checking that out now. Thanks.

[@the-wert]

12:20 - theoretically you could restore lost performance of coldplate created by such technology by recrystallization. You could test what difference (if any) would this make - just place it in oven with protective atmosphere at 400°C for a few hours.

This is a nice test you have going and would add a few blocks you could test as well.

I got the raystorm 280 kit with a x79 board, do to fluid in the res falling below half and barfing its fluid. I have have been using it for some year, with a d5 aalpacool eisstation instead. Im moving all that to server duty and got a x299 board to replace it, going to used use a 7th gen chip and your direct die kit.

I know lots fit it, but they don't all do very well for the coverage. Especially since it's much bigger, as well as a rectangle. The 'best' I have been able to find is something that is good for, compatible with the LGA 2066.

[@RetroTinkerer]

I was told "a while ago" by one notorious tech youtuber famous for its water cooling builds that there was no reason to review custom liquid cooler parts for their performance and a sponsored build was a perfect way to show of the parts. A medium one that used science in his handle also told me hey people build custom water for the way they look, no performance review is necessary. I guess corsair is a big sponsor and a performance review of underperforming parts is always unnecessary. BTW Thanks for the review and for actually testing the parts!

[@Hagop64]

Do these blocks have a specified flow rate or pump pressure given? You mentioned you tested them at 30% so I wonder if different blocks could be affected by this or if they were optimized to cool at a certain flow rate. It would have been interesting to see the comparison between 30% and 100% to see if all that extra noise is worth it or if there is a block that sees a non-proportional change in performance (ie at 30% it was 5th in performance compared to others but at 100% it was 1st.)

[@arthurmoore9488]

This is the disadvantage to standardized testing. Not that the results are "wrong", but A - B testing when components are optimized for certain conditions means a poor performer optimized for the exact test will do good even compared to the good ones that work across a broader range. Interestingly, this also applies to vehicle emissions. If you don't drive your car the same way the emissions tests are designed then it is often allowed to produce far more pollution than you'd think!

[@NINEWALKING]

When the video started, I thought Roman was testing my block as well. Packaging had a similar picture on it. I am a bit creature of habit. When some company gets me with their good performance, I stay with them until they eventually disappoint me. Currently, I still buy EK products, and they serve me well. My cyrrent CPU block is EK Quantum Velocity2 1700 full nickel. When 12900K came out with a new 1700 socket, I had to get a new water block. This mounting system and cleanness of the install both me. There is nothing to see from the top. You see, just a beautiful water block that looks like bonded to the mainboard. Knowing that most of the top brands' blocks perform very similar and with my giid experience with the EK, I've went for it. I do not own any other 1700 socket water block to compare it with, but my CPU Temps are great. It really depends on what you configure in the bios, to be honest. If I configure full tilt and allow CPU to pull all it wants, it is pulling over 300 Watts in the Prime95 small FFT, and it reaches thermal cap off 100 and then runs on 98 to 99 degrees. Load line calibration mode 2 archives same benchmark results, but Prime95 small FFT pull 260-ish Watt. That results in 80-ies temperature. Whoever thinks that's high, get Prime95, and run it stable for an hour with a small FFT option. Cinebench pulls like 50 Watt less than even default Prime95 test. Small FFT is pure torture. In everyday gaming, my CPU is at a low 60-ies range. That with very quiet system. BTW, that's mount without the contact frame. I have one but I am waiting for 14900K and will use it when that comes in.

Impressive. I happen to be using a Cuplex w/NEXT Vision display, the acetal top version and raw copper. Fantastic performance, I actually liked the mounting system coming from my old Eisbaer. I'm using it on a z590 though, Maximus Hero with 11900k. Pulling 290w reported in Hwinfo, my max temp thus far is 76c. Pretty regular loop, it's my first. A Nexxos 360mm and 420mm. Kryonaut of course, but not Extreme. The price here in the states for this version was $104 USD so I am extremely happy with my purchase, considering it's also made in Germany and has an integrated coolant temp sensor and OLED display with a lot of functionality. Side note: For the next version of Wireview, please make the display rotatable. I bought one and cannot use it with my Aquacomputer block w/active backplate :c Probably should have seen that coming, but I did not start my build for long after the return period so it's 100% my fault.

the material science part about deformed metal having reduced thermal and electric conductivity was super interesting.

Please compare them with EK-Supremacy EVO! You're amazing and the content is excellent. Thank you for the huge effort you're putting into these tests!

I would love to see a comparison between Acryl version and full copper version of both Aquacompter and Heatkiller blocks. I plan to buy a Heatkiller IV full copper for my upcoming build.

[@peteb5343]

The fact you actually have a Heatkiller impressed me..

[@sergeys2505]

Fantastic job, man 👍

[@der8auer-en]

thanks!

I wonder if annealing the copper block after skiving the fins would improve the thermal transfer. If so, it might end up being better overall and faster to produce than finely machined fins.

The Corsair blocks should come with an adapter to standard A-RGB in the box, at least the one I got did.

[@helljester8097]

Yeah same here they’ve been including more and more of these adapters with hydro X products.

[@ThunderingRoar]

i ll rather just avoid all corsair rgb products instead
