Watercool HEATKILLER V ULTRA for RTX 5090 ASUS TUF ACRYL Ni aRGB (15688)

The new HEATKILLER V graphics card coolers for the ASUS RTX 5090 TUF graphics cards represent a consistent further development of the already successful RTX 4090 graphics card coolers, optimized for maximum performance.

Key features of the HK V ULTRA series:

• Modular ULTRA - Performance base plate


• Dual Layer Inflow


• Symmetrical cooling design


• Design-integrated connection threads in the connection module


• Connection module screwed to copper base plate


• Screwless design thanks to magnetic holding system


• aRGB board with improved connector system

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

With 100 x 0.15mm fins, our current Ultra-Performance base plate sets the standard for water-cooled graphics card coolers. The ULTRA version has a larger cooling surface than the PRO version, ensuring better temperatures. The Ultra-Performance base plate is currently considered the benchmark in the water cooling field.

All gaps to heat-sensitive components have been minimized, ensuring optimal heat dissipation from thermally sensitive areas such as the RAM and voltage converter. Precisely fitting spacers ensure perfect stability and optimal force distribution between the cooler, graphics card, and backplate.

The entire unit was specifically designed for the ASUS RTX 5090 TUF to achieve maximum performance.

Dual Layer Inflow and Symmetrical Cooling Design

The dual-layer airflow, as well as the symmetrical cooling design, are found in the current version of our HEATKILLER V GPU cooler. The increased airflow is particularly important for the ultra-performance base plate.

Dividing the water into two levels ensures better airflow through the cooler. The symmetrical flow paths, which were implemented through extensive flow simulations, optimize the flow and thus the overall performance of the HEATKILLER V cooler.

Screwless front design easy maintenance

The newly developed magnetic mounting system enables a screwless front design. It also ensures quick access for maintenance or the installation of an aRGB board.

High-performance thermal pads for GDDR7 RAM

Our development department invested a lot of time in finding the ideal thermal pads for graphics card memory. We found a thermal pad that lowers the temperatures around the memory compared to the very good standard pads.

Design-integrated side connection module

To ensure optimal airflow and compact dimensions, the connection module was integrated into the design. For increased stability, the module is screwed to the cooler's copper base plate. Together with the screwless cover and the included backplate, the cooler appears to be a single unit. A connection module with side connection threads is also available

Backplate and aRGB in the package

The cooler's mounting system has been completely redesigned. Unlike previous versions, the entire cooling unit is screwed to the backplate. This not only simplifies installation but also optimally distributes the contact forces, further increasing cooling performance. In addition to the impressive appearance, this also achieves better temperatures.

The aRGB board used now features a modular design and a compact plug-in system. Implementing it as a printed circuit board ensures greater durability. Thanks to the high compatibility of our LEDs, the Heatkiller V cooler can be integrated into any lighting concept. The plug-in system also allows the cooler to be used easily without lighting.
