EKWB EK-Nucleus AIO CPU Cooler CR240 Lux, Digital RGB, Black

I needed a new cooler to replace an Arctic Liquid Freezer II 240 on 7950x in a Lian Li Q58 due to it getting too warm and also because I could not close the side panel. This EK AIO has no reviews as of this review but I have built many custom loops with EK components before so I was comfortable with the brand. The packaging of the AIO and specifically the mounting hardware would put Apple to shame. It was a wonderful experience unboxing the cooler. For the fans, originally I planned on swapping them out and replace with Noctua IPPC 2000 RPM fans. Upon receiving the aio, I decided to keep the fans as is for multiple reasons. One these are RGB and have a custom 7 pin (PWM and aRGB) connector for daisy chain making cable management easier. The fans can run at full speed of 2400 RPM and pushes decent amount of air while staying remarkably quiet. Not Noctua-quiet but very close. Pump: the pump in this AIO is the only PWM pump in the market that I am aware of which makes EK unique. At 80% PWM the pump runs at 2900 RPM and is extremely quiet to the point I could not hear it even if Iturn off all the fans. The arctic liquid freezer II claims to have PWM pump also but that is false advertising as the only component that supports PWM are the fans. Performance: running Ryzen 7950x without undervolting or overclocking, fans at 2100 RPM (pretty quiet), CPU sitting at a cool 56 degrees C during a 10 min Cinebench R23 run, for which it scored 34K. Running the CPU with auto boost and PBO, fans at 2400 rpm (louder but not too bad), CPU settled at 82 C and scored 38K. The only issue I encountered is the threads on the radiator. Not all the mounting points are fully tapped and it took some force to use the screws as tap.

one of the easiest to build with and the fans are extremely quiet temps are really low and the quality is worth the price. This fit in my ITX build

Really Good All-In-One water cooling solution for the Ryzen 7 7600x for around $110. The instillation instructions were clear and concise making the overall instillation pretty easy and stress-free. The quality is admirable and can easily go with any aesthetic. The RGB can be easily controlled with Aura software and looks smooth with changing hues. Although I did replace the front cover of the Nucleus from the EKWB official website, the one that came stock with it still looks very nice. I do wish there was an LCD front cover EKWB would sell or come stock with it. Under heavy CPU load temperatures never went above 85 deg. C with the be quiet aesthetic fans being a bit worse that the ones that came with the AIO. Under light CPU loads, temperatures sustained between 40-50 deg. C. With the pump spinning at max speed, it is pretty inaudible. I would recommend.

Have been using EK water cooling products since I first started building PCs years and years ago. Have never had an issue with one of their products until this one. Can’t wait to say whether the blame is on EK, or the reseller, but as shown in the pictures, the radiator has a bent fin that is easily visible (see mid left corner of last photo). What’s even worse is that the mounting screws for the radiator don’t even fit the mounting holes on the radiator. They aren’t even close to being the right size. Just for reference I screwed a couple in as far as physically possible just to show that they aren’t the correct size. I’m sure this would have been another great product from EK, but can’t even use or test it because of these issues!

First thing I noticed is the very premium packaging and a very smooth installation experience. It fits very nicely in my A4-H2o, with some creative routing of the tubes. I did need to remove the RGB LED logo cover to have it fit within the 55mm restriction. Performance is exceptional. Keeps my 7800x3d under 75c on long prime 95 runs. Costs a bit extra, but worth it.

The mounting system, packaging, product quality are fine, what you'd expect from EK. However, for me, an AIO liquid cooling is about 2 things; Noise level & cooling capabilities. I literally don't care about RGB or the physical aspects. The pump is noisy, keeps making bubbly sounds along with a relatively high pitch continuous sound that I can only force to go away if the pump speed is set at 30% which is ridiculous. The 2 fans also have vibrations and are not as quiet as you'd expect them to be, granted I have an all-mesh case "Asus AP201" but you can still tell that those fans are not quiet at all. For the cooling performance, 240 AIO kept my 13700K on a leash never going beyong 83C. Which is fantastic, but the cost was the higher db floor.

I wasn't aware of this brand until I read around on newer AIO's as the one I had originally installed started making a lot of unsavory noises. So, after reading some other reviews, I gave this cooler a shot, it's great. It's working as expected and keeps my 14900 / 7950x3d CPU's cool and quiet. So, I expected it to cool well, but what got me the most was the packaging. So well done and clean, I was surprised as you only get that "quality" packaging feeling from overpriced brands. I ended up buying a 2nd one for my other CPU (mentioned above). Give it a shot, well worth the money.

Installation initially proved challenging, as the screw holes on the radiator (both fan side and mounting side) were not pre-threaded on the unit received. Attempts to mount the radiator required excessive force. Once notified of the issue, EK Customer Service advised that the radiators are painted after the threads are made, and that there may have been too much paint on the threads; however, they were quick to resolve the issue after further discussion and send a replacement. Installation of the replacement went much smoother with minimal resistance from the mounting screws. While the initial defect may pose QC concerns, I am ultimately satisfied with the EK team's responsiveness. Depending on the longevity of the product (TBD), I would consider purchasing again in the future.

You will not be dissapointed :)

Produits très facile d installation, plusieurs adaptation possible. Je suis passé de 85/90 degrés à 45 degrés, max 60 en game. Mon pc revit 👌

If you are looking for easy to use mounting hardware, good performance and affordable price, there isn't a better option on the market. You CAN get a better performing AIO at this price, but it would look significantly worse. You CAN get an AIO with an LCD screen, software, etc. but it would be a lot higher priced. My one gripe about the product is that it doesn't have a coolant temperature sensor. That would make it absolutely perfect.

ekwb - EK-Nucleus AIO CR240 Lux D-RGB nach genau einem Jahr war die WK kaputt und brachte die Hitze nicht mehr von der CPU weg. Sehr schade, denn warten kann man sie nicht. Für solch eine kurze Haltbarkeit kann ich nur einen Stern vergeben, den sie ist dafür zu teuer und ich mags auch nicht unnötigen Elektromüll zu produzieren. leider gibt es hier bei Amazon keine Möglichket Support zur Problembehafteten Firma EK zu bekommen, weshalb ich trotz Garantie auf dem Schaden sitzen bleibe. Von der Verarbeitung war sie gut und Lautstärke OK, die Pumpe allerdings nur im runtergeregelten Zustand, da sie ansonsten ein unangenehmes geräusch gemacht hat. Der Einbau war einfach aber was soll da bei einer AIO auch groß schwierig sein. Die LEDs liesen sich mit Aura Sync einfach einstellen. Der Kühl und Pimpemkörper ist nicht Mini-ITX geeignet da einfach zu hoch. bei mir hat er nur reingepasst weil ich die Farbspielkappe ab lies. Wegen dem fehlendem Support und damit eingehendem nicht bekommen meiner Garantie rate ich von EK Produkten ab.
