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.

Was able to cool 14700k with this 240mm thing, which is a serious feat. Noise is considerable (under high cpu load, otherwise aio is silent), but that’s what you get for cooling one of the hottest cpus on the market. Performance is at the top level. Best 240mm aio by far.

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.

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.

Really great 240 AIO. Construction and finish quality is top notch and much better than other mainstream AIO offerings. Installation was a breeze and couldn't be any more simple. Unbelievably quiet! I run my pump at 85% and it's absolutely inaudible. Looks amazing in all black. ARGB works perfectly. Also the packaging and instructions were really well done. I can't think of any downsides??? Edit: Ran Cinebench R23 three times straight, about 30 minutes of heavy CPU load. At 205 watts sustained, my CPU topped out at 73 degrees. Definitely a legit AIO.

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 bought an EK 240 BASIC AIO recently and it failed 6 months later, bought this to see if maybe it was a fluke and their newer stuff is better. Honestly yes this is great, but it sucks that I already purchased one AIO from this manufacturer to have it fail in months then buy another more expensive solution for longevity. 3 stars since I finally got what I paid for. Edit 01.02.2024 This AIO also died after only a few months of use. One star for the product and never buying an EK solution ever again. Disappointing waste of time and money spent on this awful component.
