Watercool HEATKILLER V PRO for RTX 5090 ASUS TUF Ni-Bl aRGB GPU Water Block, G1/4, Nickel Plated Copper (15685)

A full-cover water block for the ASUS TUF Gaming GeForce RTX 5090 and its OC Edition. The Watercool HEATKILLER V PRO for RTX 5090 ASUS TUF Ni-Bl aRGB combines a nickel-plated electrolytic copper base with an acrylic cover, black anodized aluminum trim and pre-assembled aRGB lighting. It cools the GPU, the memory and the voltage converters. The backplate is in the box.

Made for one card

According to Watercool, the new HEATKILLER V graphics card coolers for the ASUS RTX 5090 TUF graphics cards represent a consistent further development of its already successful RTX 4090 coolers, optimized for maximum performance. The entire unit was designed specifically around the ASUS RTX 5090 TUF board to achieve high performance. These are the key features of the HK V PRO series:

• Modular Pro-Performance base plate with 60 x 0.25 mm fins
• Dual layer inflow as well as a symmetrical cooling design
• Design-integrated connection threads in a connection module that is screwed to the copper base plate
• A screwless front thanks to a magnetic holding system
• An aRGB board with an improved connector system

Modular Pro-Performance base plate

Watercool says its current PRO Performance base plate, with 60 fins of 0.25 mm, sets the standard for water-cooled graphics card coolers. In its words, the base plate of the Pro version is currently considered the standard in the water cooling sector. The PRO version uses a generously sized cooling surface whose channel geometry gives high flow rates and performance.

All clearances to heat-sensitive components have been reduced to a minimum, ensuring the best possible heat dissipation from thermal problem areas such as the RAM and the voltage converters. Precisely fitting spacers ensure perfect stability and an optimal force distribution between the cooler, the graphics card and the backplate.

Dual layer inflow and symmetrical cooling design

Both are found in the current version of the HEATKILLER V GPU cooler. The increased inflow is particularly important for Watercool's performance base plates. Dividing the water into two levels gives a better flow through the cooler. The symmetrical flow paths were implemented through extensive flow simulations, and they optimize the flow and thus the overall performance of the block.

High-performance thermal pads for GDDR7 RAM

Watercool's development department invested a lot of time in finding the ideal thermal pads for graphics card memory. Watercool says the pad it found lowers the temperatures around the memory compared to the very good standard pads.

Compatibility

Watercool lists two boards for this block. The same block also comes in a nickel version with natural anodized trim.

• ASUS TUF Gaming GeForce RTX 5090
• ASUS TUF Gaming GeForce RTX 5090 OC Edition

Notes

• Take off the pre-mounted backplate first; its red plastic washers are only transport protection and must be removed.
• Watercool recommends demineralized or deionized (distilled) water with a suitable corrosion inhibitor as coolant.
• Removing the original air cooler may affect or void the graphics card warranty.

In the box
