REFURBISHED - Watercool HEATKILLER IV GPU Water Block for Radeon RX 5700 / XT, Acetal Ni

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. All relevant secondary components, such as memory or voltage regulation modules are also directly cooled by the coolant.

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.
