Watercool HEATKILLER V ULTRA GPU Water Block for RTX 4090 FE, Acrylic Ni

The new HEATKILLER V Ultra graphics card coolers for Nvidia's RTX 4090 Founders Edition graphics cards are an uncompromising further development and versions of the already very powerful Pro coolers optimized for maximum performance. Proven technologies such as the dual-layer inflow and the symmetrical cooling design are also back on board.

Important key points of the HK V ULTRA series:

• Ultra Performance 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 stripes
• CNC cut thermal pads

Modular ultra-performance base plate with 100 x 0.15mm fins

With 100 x 0.15mm fins, our current ultra-performance base plate sets a new standard for water-cooled graphics card coolers. The ULTRA version has a significantly larger cooling surface compared to the PRO version, which ensures significantly better temperatures. The ultra-performance base plate is already considered a reference in the water cooler sector.

All distances to hot components have been reduced to a minimum, which ensures that the heat from thermal problem areas such as the GDDR6X RAM and the voltage converter is optimally dissipated.

The PEEK spacers made from high-performance plastic ideally insulate the cooler from the circuit board and make installation easier. The legendary Kryonaut thermal paste from Thermal Grizzly ensures the best possible heat transfer.

Dual layer inflow and symmetrical cooling design

The dual-layer inflow, like the symmetrical cooling design, can also be found in the ULTRA version of our HEATKILLER V GPU cooler. The increased inflow is particularly important for the high-performance base plate. Splitting the water into two levels ensures 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 in finding the ideal thermal pads for the hot GDDR6X RAMs. We have found a thermal pad that significantly reduces the temperatures around the GDDR6X RAM compared to the very good standard pads.

Design-integrated side connection threads

Another innovation is the connection threads integrated into the side of the terminal. Together with the screwless panel and the backplate included in the package, the result is a cooler that looks like a unit.

In order to achieve the best possible appearance, the HK V ULTRA was designed so that no electronic components on the board can be seen.

Backplate and aRGB in the package

The new cooler design relies on assembly including a backplate. In our case, the black backplate ensures improved distribution of forces around the cooling block. In addition to an impressive look, this also results in better temperatures.

The aRGB stripes used now have a modular structure and a compact plug-in system. Thanks to the high compatibility of our LEDs, the Heatkiller can be integrated into any lighting concept. The plug-in system also allows the cooler to be used quite easily without lighting.

Made in Germany

Production is carried out with the greatest care on our state-of-the-art CNC machinery in Waren an der Müritz. Many work steps are carried out by hand and each product is completed according to the four-eyes principle. Made in Germany, as you would imagine.
