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. Review: works well and feels premium - 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 ### ⭐⭐⭐⭐⭐ Great 240mm AIO paired with Ryzen 7 7600x! *by A***R on March 24, 2024* 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. ## Frequently Bought Together - EK Nucleus AIO All-in-One Liquid CPU Cooler with EK FPT Fans, Water Cooling Computer Parts, 120mm Fan, Compatible with Latest Intel & AMD CPUs (240mm, Nucleus - CR240) - Thermal Grizzly Kryonaut - 1 Gram - Extremly High Performance Thermal Paste - for Demanding Applications and Overclocking CPU/GPU/PS4/PS5/Xbox - AMD Ryzen 7 7800X3D 8-Core, 16-Thread Desktop Processor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/503985020-ekwb-ek-nucleus-aio-cpu-cooler-cr240-lux-digital-rgb](https://www.desertcart.co.za/products/503985020-ekwb-ek-nucleus-aio-cpu-cooler-cr240-lux-digital-rgb) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-01*
