1. Watercool Heatkiller Tube - Basic AGB Mounting Kit

The use of the bracket is incredibly simple. You just slide the bracket onto the struts to the desired position and then secure it using the countersunk screws attached to the side. On the back of the bracket, there are M4 threads that allow the bracket to be screwed onto the case wall. Vibration-dampening mounting is also possible, as decoupling modules are included in the delivery. With optionally available adapters, the expansion tank can also be mounted to mounting holes for fans in the sizes of 120 x 120 mm or 140 x 140 mm. This allows the expansion tank to be mounted, for example, to a radiator from the HTSF2 series. An adapter for mounting the expansion tank to a radiator from the MO-RA3 series is also available. Technical specifications: Material: POM (Acetal), Color: black. Delivery includes: 1x HEATKILLER® Tube - Basic Mounting Kit, mounting materials.

4. Alphacool Cape Corp Coolplex Pro 10 LT

The Alphacool Cape Coolplex expansion tanks have been a well-known presence in the water cooling market for many years.

Even such fundamentally solid products need an update to meet the latest demands. Therefore, we at Alphacool have phased out our last series and are now launching our tanks, newly made from POM under the name "LT" and from full metal in the "Copper Edition." Of course, the tubes are again made from high-quality Plexiglas, which has reliably operated in your PC in the past.

The updates are remarkably simple: In addition to the new colors, an additional threaded opening has been incorporated into the lid of the expansion tank. This makes filling with a fill port easier. Furthermore, this tank can now also be mounted flat! The riser tube, which is normally intended for venting the system, can now be unscrewed, as it is no longer needed when the inlet comes from above. A nice side effect: We now have more space for lighting modules and can showcase our new tank even better! To further enhance the overall concept, all closure screws for both models will be delivered in shiny copper.

Traditionally, all threads are sized at ¼”. Our well-known transparent mounts are also included in the package: This way, the tank becomes a wonderful eye-catcher for your PC under the glow of an LED!

Note: Additional screws are required for installation. 

5. EKWB EK-Quantum Kinetic FLT 240 D5/DDC Body D-RGB - Acrylic

The EK-Quantum Kinetic FLT 240 D5/DDC Body D-RGB is an innovative reservoir for water cooling systems, specifically designed for integration with DDC or D5 pumps. This standalone device allows users to utilize their existing pump, providing a cost-effective upgrade option. The reservoir features a modern, flat design that facilitates installation in standard PC cases without the need for additional drilling. With a total of six G1/4" ports, the Kinetic FLT 240 offers numerous options for tubing routing and the implementation of drain or fill valves. Made from high-quality acrylic glass, the reservoir ensures excellent visibility of the coolant, while a black anodized aluminum cover and an addressable D-RGB LED strip provide appealing lighting. The careful construction and use of EPDM O-rings ensure reliable sealing and durability of the product.

- Standalone reservoir without an integrated pump, allowing the use of existing DDC or D5 pumps
- Flat reservoir design for easy installation in standard PC cases
- Six G1/4" ports for flexible tubing routing and additional options for drain and fill valves

6. Alphacool Ice cream sundae Helix

The Alphacool Eisbecher Helix 250 is a visual highlight of the Eisbecher family. The helix inside the reservoir creates a special effect reminiscent of a DNA strand, making it a true eye-catcher. In the center of the reservoir, there is a UV cathode tube powered by a 3-pin connector. When UV-reactive water is used, it produces a strong glow from within the container, creating a truly impressive effect.

The bottom and the lid are made entirely of acetal but are covered by aluminum caps for an elegant look. The aluminum caps do not come into contact with the water. The connection options are extensive, with three G1/4" threads located in both the lid and the bottom. Additionally, there are two more G1/4" connection options on the side of the bottom. This allows for various mounting positions. Two different mounting sets are included: the aluminum brackets known from the Eisbecher series, which align flush with the top and bottom of the Eisbecher Helix and allow for mounting the reservoir on a radiator. This requires a 240 mm or 280 mm radiator or a larger counterpart, such as a 360 mm or 420 mm radiator. Alternatively, clip mounts are provided, which can be secured to the case with a screw. The Eisbecher Helix can simply be clipped in here, offering flexible options for mounting.
