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 create 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.

Considering secondary components, we didn’t settle to only cool the VRAM and the first row of MOSFETs. The biggest coldplate we ever made for a Single GPU card with 800 grams of pure electrolytic copper covers the entire PCB. Not only does it provide an optic highlight by finishing all edges around the block with copper. It also gives us the ability to really cool all components for which Nvidia requires cooling in this generation: this includes not only all the MOSFETs and coils of the VRMs, but also several additional small components of the power circuitry. This guarantees a smooth and stable power delivery under load scenarios, which can provide better overclocking results and stability.

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.
