1. Watercool Heatkiller V für RTX 3080/3090 - Nickel + Acetal
With the HEATKILLER V, Watercool is launching a new generation of coolers for Nvidia RTX 30 graphics cards. Equipped with unique highlights, the current version of the HEATKILLER V presents what is technically feasible. An increased number of cooling fins increases the cooling capacity directly above the graphics processor and thus improves the most important area. The cooler base, milled from a solid block, ensures contact with all relevant components. The directional dual-layer inflow distributes the water simultaneously on two levels. This ensures an inflow that is at least 30 per cent higher than that of the previous generation. The wide and symmetrical flow paths reduce dead spots (stagnant water) to a minimum and accelerate the flow. The overall result increases not only the maximum cooling capacity but also the flow rate of the HEATKILLER V. Thanks to newly designed spacers made of high-performance plastic (PEEK), the 10 mm solid copper block is ideally insulated from the circuit board. In addition to the technical innovations, the design of the cooler is also impressive. The screwless cover makes the entire block look as if it has been cast from a single mould. The symmetrical channels further emphasise the look of the cooler and make it a unique eye-catcher.
