The new HEATKILLER V graphics card coolers for Palit and Gainward RTX 5090 graphics cards are the consequent further development of our already very successful RTX 4090 graphics card coolers, optimised for maximum performance.

Key features of the HK V ULTRA series:

• Modular ULTRA - performance base plate
• Dual layer airflow
• Symmetrical cooling design
• Design-integrated mounting threads in the connection module
• Connection module screwed to copper base plate
• Screwless - more compact design
• aRGB board with improved connector System
  

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

With 100 x 0.15mm fins, we are setting the standard for water-cooled graphics card coolers with our current ultra-performance baseplate. Compared to the PRO version, the ULTRA version has a larger cooling surface, which ensures better temperatures. The Ultra-Performance base plate is currently considered the reference in the water cooling sector.

All spacing to heat-sensitive components has been reduced to a minimum so that the heat from thermal problem zones such as the ram and voltage converters is ideally dissipated. Precision-fit spacers ensure perfect stability and the best possible distribution of forces between the cooler, the graphics card and the back plate.

Dual-layer inflow and symmetrical cooling design

The dual-layer inflow and the symmetrical cooling design can be found in the current version of our HEATKILLER V GPU cooler. The increased inflow is particularly important for the ultra-performance base plate. The division of the water into two levels ensures a better flow through the cooler. The symmetrical flow paths, which have been implemented through extensive flow simulations, optimise the flow and therefore the overall performance of the HEATKILLER V cooler.

High-performance thermal pads for GDDR7 RAM

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

Design-integrated side connection module

Another innovation is the connection threads integrated into the side of the module. For additional stability, the connection module is screwed to the copper base plate of the cooler. Together with the screwless panelling and the backplate included in the package, the result is a cooler that looks like a single unit.
In order to achieve the best possible design, the cooler has been designed so that the e
