Rotatable pump top with the top, you can realign the D-RGB EK badge regardless of which direction the cooler is installed. The orientation can be changed in increments of 90°. So if the cooler is installed upside down, rotate it 180 degrees to display the logo directly up. Regardless of the angle needed to install the AIO, it always offers a clean and aligned aesthetic.
New positioning of swivel fittings - The AIO CR360 Dark is pre-installed with reinforced and worse rubber hoses with finer threads. The fittings are covered with an aesthetic black radiator cover when connecting hose and radiator to ensure a sleek design and rinsed line with the additional fans. The improved position of the swivel fittings on the other side, now placed side by side, allows the EK-Nucleus AIO to install even in confined spaces.
Microfin Copper Plate - The copper cold that touches the CPU IHS is made of copper to improve heat transfer properties. It features a dense stack of microfins that increase the thermal transmission range between copper base and coolant, ensuring unparalleled cooling.
High static pressure FPT fans want the fans of the EK Vardar to be fully successful as they improve many aspects while maintaining the focus on excellent cooling performance. FPT fans feature a full frame design where no air escapes outside the frame, thus achieving better static pressure.
Generally compatible - All EK Nucleus AIOs are equipped with a universally compatible CPU water block that offers the latest Intel and AMD CPU sockets (LGA 1700 and AM5). The installation process is very simple thanks to the included manual and mounting mechanism. This product requires enough space to mount a slim 240mm radiator, making it compatible with almost all modern cases.

[TRCC Control Center] Please confirm the completeness of the wiring before installing the software. The software can be downloaded from the official website, and the real-time data monitoring, data transmission, and on/off functions of the LCD screen are all controlled by the software. For more detailed analysis, click on the "?" icon in the upper right corner of the software.
[Optimization of Details] Pre installed 3 fans for cold row, simple installation, wireless splicing design for PWM fans, can solve the problem of cumbersome wiring. The power supply interface of the fan is 4pin PWM, and the lighting interface is 5v 3pin ARGB. The accompanying SS2 buckle system is compatible with multiple CPU models.
Wireless Splice-3 Fan: Paired with TL-M12Q CPU fan, it has temperature control function, ARGB line embellishment, and infinite mirror lighting effects at the top and bottom, enhancing the appearance of the PC fan. The brand new power module control line transmits signals and power between fans through contacts. A high speed of 2000 revolutions per minute combined with cold exhaust and water pump can quickly remove high temperatures.
RGB Divine Light Synchronization: The ARGB of the fan and water cooling head synchronises with the 5V 3pin on the motherboard, providing efficient cooling and rich lighting effects. The color of the lights can be adjusted according to the motherboard's lighting software.
Excellent cooling effect: Using a visual digital water block + 360 specification aluminium fin radiator + polymer braiding protective water pipe + standard 120 mm infinity mirror lighting effect CPU fan, we are committed to creating a CPU cooler with low resistance, high cooling and visualization.
Excellent bearings: The fan adopts STABLY-FDB bearings (referred to as S-FDB bearings), which can solve the problem of fan blade vibration in lifting mode and greatly improve the performance of the cooling fan. The longer service life ensures the long-term cooling of the CPU by the radiator, and the corner pads around the fan also play a role in shock absorption and noise reduction.
