After an amazing Watercool Heatkiller CPU water block, it’s time to test cooling for video card and more precisely for Nvidia GTX1080 Ti. In this review we will show you how to install the Heatkiller water block and how it performs on one of the most demanding graphics card on the market.

After this short introduction, couple of words from Watercool about the latest graphics card cooling solution.

HEATKILLER® IV VGA

Made from enthusiasts for enthusiasts

The HEATKILLER® IV VGA series is the climax of 15 years of experience in designing and manufacturing high-performance water cooling equipment. Only the best features of the previous generations were merged together to provide an even more powerful water block.

We continued the GPU cooling structure of the successful HEATKILLER® GPU-X³ series and enhanced it with the central flow design, already known from the HEATKILLER® GPU-X² series. Then, we did some improvements: the combination of an extremely fine microstructure right above the GPU and a reduced residual base thickness deliver even better cooling performance. We also improved the overall flow rates by constructing all channels as wide as possible. All relevant secondary components, such as memory or voltage regulation modules are also directly cooled by the fluent.

Another highlight of the HEATKILLER® IV for TITAN X and GTX 1080Ti is hidden under the black POM side bracket: you can find a precision milled groove in the acrylic glass here. This groove is the perfect preparation to illuminate your waterblock. You can simply install one of the LED strips here and directly connect it to the onboard LED connector (Strips sold separately)!

Thanks to preinstalled insulating spacers, the installation of the block onto the graphics card is really simple.

The HEATKILLER® IV VGA series is manufactured from high-quality materials only: we only use highly purified electrolytic copper and the original PLEXIGLAS® GS from EVONIK for our products. All our products are completely manufactured on our own modern machinery park in our own workshop in Germany.

Pre-cut thermal pads for RAM (VRAM) and voltage regulation module (VRM) are already included, along with the installation materials, and an installation instruction.

In order to connect several HEATKILLER® IV VGA water blocks in a Crossfire/SLI setup, the GPU-X Dual-Link and GPU-X Multi-Link accessories are sold separately. A backplate is also available.

For information on compatibility, please refer to the compatibility list for HEATKILLER® VGA coolers.

The Heatkiller IV for GTX 1080Ti is available in Watercool online store for €114.95.
