Watercool HEATKILLER V ULTRA for RTX 4090 ASUS STRIX/TUF Acryl Ni aRGB

The new HEATKILLER V Ultra graphics card cooler for ASUS RTX 4090 STRIX and TUF graphics cards is an improved version of our already very powerful Pro cooler, optimized for maximum performance without any compromises. It also includes well-proven technologies such as dual-layer inflow and the symmetrical cooling design.

Key features of the HK V ULTRA series:

• ULTRAPerformance base Plate
• Selected high performance thermal pads on GDDR6X RAM
• Dual layer inflow
• Symmetrical cooling design
• Design-integrated connection threads in the terminal
• Screwless design
• Insulating spacers made of high performance plastic (Peek)
• Plug-in system for aRGB strips
• CNC cut thermal pads

Modular ultra-performance base plate with 100 x 0,15mm fins

With 100 x 0.15mm fins, we are setting a new benchmark for water-cooled graphics card coolers with our newest ultra-performance baseplate. In comparison to the PRO version, the ULTRA version features an massive larger cooling surface, which ensures significantly better temperatures. The Ultra-Performance base plate is therefore already considered the reference in the water cooler sector. All clearances to hot components have been reduced to an absolute minimum, ensuring that heat from thermally problematic areas such as the GDDR6X ram and the voltage converters can be dissipated optimally.

The PEEK spacers made of the high-performance plastic isolate the cooler optimally from the PCB and simplify the assembly. Thermal Grizzly's legendary Kryonaut thermal compound ensures the best possible heat transfer.

Dual Layer Inflow and Symmetrical Cooling Design

The dual-layer airflow and the symmetrical cooling design can also be found in the ULTRA variant of our HEATKILLER V GPU cooler. The increased inflow is especially important for the ultra-performance base plate. The division of the water on two levels ensures a better flow through the cooler. The wide and symmetrically designed flow paths optimize the flow and thus the general performance of the HEATKILLER V ULTRA cooler.  

Selected high performance thermal pads for GDDR6X

Our development department has invested a lot of time to find the ideal thermal pads for the hot GDDR6X RAMs. In the process, we found a thermal pad that significantly lowers temperatures around GDDR6X RAM compared to the very good standard pads.  

Design-integrated lateral connection threads

Another innovation is the connection threads integrated into the side of the terminal. This together with the screwless fairing and the backplate included in the package results in a cooler that looks like a single unit. To achieve the best possible appearance, the HK V ULTRA was designed so that no electronic components of the board are visible.  

Backplate and aRGB in one package 

The new cooler design relies on an assembly including a backplate. In our case, the black backplate ensures an improved distribution of forces around the cooling block. In addition to an impressive look, this also results in better temperatures. The aRGB strips used now rely on a modular design and a compact plug-in system. Due to the high compatibility of our LEDs, the Heatkiller can be integrated into any lighting concept. However, the plug-in system also allows the cooler to be used without any Illumination.  

Made in Germany

The production takes place with the greatest care using our state-of-the-art CNC machinery in Waren an der Müritz. Many work steps are carried out by hand and each product is brought to perfection according to the four-eyes principle. Made in Germany as you would expect it to be.
