Big, Bigger, SuperNova! 400 x 400 x 45 mm of pure cooling surface for nine 140mm or four 200 mm fans. No other Alphacool radiator offers as much surface area in a single product.
Make No Compromises, Use Copper.
As usual, Alphacool also uses pure copper for the NexXxoS 1260 SuperNova Radiator. The end chambers, water channels and cooling fins are all made of copper and are a unique selling point worldwide. As a result, Alphacool radiators have been among the most popular and best on the market for many years, providing the perfect foundation for every water cooling system.
Full Cooling Capacity
To maximize the performance of a radiator, Alphacool reaches deep into its bag of tricks. Copper is the starting point. With a thermal conductivity of 400 W/(mK) for copper compared to 236 W/(mK) for aluminium, the winner is clear. Alongside this is the special fin density. Alphacool is one of the oldest companies in the field of water cooling and has carried out countless laboratory tests. The result, especially for such large radiators, is a fin spacing of 12 FPI. This means that the air flow is almost unobstructed as the air can pass through even without high pressure. However, the cooling capacity does not suffer from this, on the contrary. To use the airflow optimally, all cooling fins have small serrations. These are tiny flaps that guide the airflow in the desired direction and increase the surface area. In the case of radiators, they are barely 1 mm high, but still provide controlled air turbulence to increase cooling capacity and minimise airflow noise.
Which fans?
The 1260 SuperNova Radiator offers for four 200 mm fans with a hole spacing of 154 mm on one side. On the opposite side, up to nine classic 140 mm fans can be mounted on another mounting plate. If you want to operate the radiator passively, you can remove both mounting plates. This will ensure you do not to obstruct the natural airflow. Of course, the mounting plates for both types of fans can also be interchanged. This gives you more freedom when mounting the fans.
Connection options
The Alphacool NexXxoS SuperNova Radiator offers two G1/4" threads for IN and OUT. A further G1/4" thread on the back of the radiator serves as a fill port. Alternatively, a temperature sensor or a drain port can also be attached here.
The king on the rads! No other radiator in Alphacool's portfolio can match the performance of the SuperNova radiator. With four 200mm or a whopping nine 140 mm fans and a pure cooling surface of 40 x 40 cm, it really does live up to the SuperNova name.

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 3000 rpm via the 4-pin PWM connector. The startup speed is ~500 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.
