Our MO-RA3 (Monster Radiator) is considered the best solution for almost any application. It is not only perfectly suited for maximum silent systems. Also massively overclocked gaming systems can be easily cooled by this radiator. Even 24/7 operations of servers or workstations are no problem with this solution. It is even frequently used in industrial appliances, thanks to its powerful and robust design and construction.
To cool big heat loads like that, you require big amounts of material. In one MO-RA3, we use over 36 meters (118 ft) of copper pipes, connected to more than 3 square meter (33 sq ft) of aluminum fins. The fin geometry is optimized for fans with low rotations per minute.
We organized the copper pipes in four parallel rows to minimize the flow restriction. The coolant flows through 80 parallel pipes which transfer the heat to the cooling fins. The massive overall surface guarantees high cooling performance!
Our MO-RA3 is also very popular with beginner watercooling enthusiasts. External mounting doesn’t require specialized computer cases. Equipped with the dedicated feet (sold separately), you can place the MO-RA3 wherever it matches your setup. Even putting it on your walls is possible thanks to the wall mounting kit (sold separately). Combined with quick disconnect fittings, the whole system is mobile and flexible.
The port terminals are flow optimized, as well. They offer full flexibility with three G1/4’’ ports for inlet and outlet each. Several additional threads offer mounting positions for optional accessories like HEATKILLER® Tube adapters or fan grills.
MO-RA3 420 LT
9 pcs 140 x 140 x 25 mm fans
MO-RA3 420 Pro
18 pcs 140 x 140 x 25 mm fans
Separate mounting kits for thicker fans are available. You can populate one side of a MO-RA3 LT with fans. You can choose freely which side you want to use. The preinstalled mounting brackets can be switched from one side to the other.
You can populate both sides of a MO-RA3 PRO with fans. The PRO version can host double the number of the fans than the LT version. A powerful push/pull configuration is also possible with the PRO models.
All MO-RA3® components are manufactured on our own CNC machines at the WATERCOOL headquarters in Waren, Germany. Many steps of the process are manual labor and each product is finished under dual control principle. This is truly “Made in Germany”.

High-quality, elegant as well as timeless design and technical innovation - these are the features of the Alphacool Apex Stealth metal fan. With its patent-pending decoupling technology, the robust metal frame and a special rotor, this fan certainly impresses. Not only is the Apex Stealth one of the most powerful fans, but it also remains the quietest at any speed.
• High performance and whisper quiet
• Patent pending decoupling technology
• Frame made of high quality metal
• Suitable for cases as well as radiators
• Controllable via PWM + Zero-RPM Control
Whisper Quiet
The fan blades, motor and its suspension are completely decoupled from the metal frame. For this purpose, a special damping system was placed between the metal frame and the fan, which absorbs all vibrations. This type of decoupling is a completely new system, which is brought to the market by Alphacool for the first time with the Apex fan. In addition, the impeller is equipped with a closed frame that prevents the impeller tips from fluttering at high speed, which also has a positive effect on the fan's characteristics.
Powerful All-rounder
The Alphacool Apex Stealth metal fan is a true all-rounder. It sets new standards in terms of airflow and static pressure. Therefore, this fan is not only perfect for mounting on radiators, but also provides excellent airflow as a case fan. The Apex Stealth can be controlled between 0 to 2000 rpm via the 4-pin PWM connector. The startup speed is ~420 rpm. In addition, the Stealth offers Zero RPM control, which can be used to bring the fan to a complete stop.
Apex Design
Alphacool's Apex product line represents the highest level of perfection. First-class materials and innovative technologies guarantee a unique premium product. Consisting of high-quality metal, the curved frame gives the Apex Stealth its distinctive design and fits perfectly into any PC build.
Additional Features
As usual with Alphacool, multiple fans can be effortlessly connected in series via daisy chain. The cables can be hidden in the corners of the fan so that they are no longer visible. A 50 cm PWM cable is also included as an extension. The 6-pole motor in combination with the HDB bearing (Hydro Dynamic Bearing) ensures extremely quiet operation and high durability.
