About Item
  • UNIVERSALLY COMPATIBLE - All EK-Nucleus AIOs come with a universally compatible CPU water block, fitting all the latest Intel and AMD CPU sockets (LGA 1700 and AM5). The installation process is very straightforward, thanks to the included manual and mounting mechanism. This product requires enough space to mount a single slim 240mm radiator, making it compatible with almost all modern cases.
  • ADDRESSABLE RGB - Customize your all-in-one system to match your setup with its fully addressable RGB lighting effects. This closed-loop liquid CPU cooler offers a plug-and-play solution with a fan-like D-RGB lighting effect around the pump top for all who search for that perfect RGB AIO aesthetics.
  • NEW POSITIONING OF ROTARY FITTINGS - The AIO CR240 Lux comes pre-installed with reinforced and sleeved rubber tubing, now featuring finer threads. The fittings are covered with an aesthetic black radiator cover at the connection of the tubing and the radiator to ensure a sleek design and flushed line with the added fans. The improved position of rotary fittings on the other side, which are now placed next to each other, allows the EK-Nucleus AIO to be installed in even the tightest spaces.
  • ROTATABLE PUMP TOP - The top allows you to re-orient the D-RGB EK badge no matter in which direction the cooler is installed. The orientation can be changed in 90° increments, so if the cooler is installed upside down, rotate it 180 degrees to display the logo right side up. Regardless of the angle needed to install the AIO, it will always offer clean and aligned aesthetics.
  • HIGH-STATIC PRESSURE FPT FANS - FPT series fans aim to succeed the EK-Vardar fans completely, as they improve upon many aspects while maintaining focus on excellent radiator performance. FPT fans feature a full frame design that doesn't allow air to escape outside the frame and thus achieve overall better static pressure.

    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.

    I originally bought an Artic 240 cooler but it didn’t come with the 1700 bracket and I wasn’t going to wait 30 days for them to ship one out. Took a chance on this since I have an EK pump/res in my other build and its been perfect for the last 3 years. This current build is for a adobe workstation. Its running an i7 13700k and with this cooler while under Adobe load the avg temp is around 31C with a max so far of 42C. I haven’t tried any games on it yet as that’s not its purpose but may run some Apex eventually and see how the system fares. The packaging and instructions were excellent. Everything feels way higher quality than Artic and the instructions were great. All brackets were included as well. Definitely worth the extra 60$ over the artic.

    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.
