Noctua has earned itself a reputation in the enthusiast space not only for its highly efficient air coolers, but also for its free mounting upgrade kit policy, which allows buyers of Noctua coolers to request a new mounting kit when a new motherboard socket from AMD or Intel launches, even years after they’ve purchased their original cooler. The company recently announced that it has shipped 500,000 of these free mounting upgrade kits since the project started way back in 2006 with the AMD AM2 socket. Noctua also promises that “as new sockets and architectures appear, we will continue to provide free mounting or upgrade kits where technically feasible.”

Noctua explains that the ethos behind the program is to “ensure that a quality product remains useful for many years,” and, in the blog post celebrating the achievement, it explains that change in approach meant rethinking the design of its coolers. New coolers designed by Noctua from 2006 onwards would need to be modular and standardized to maintain support across different platforms and generations. Noctua elaborated that part of the justification for the past and ongoing commitment to the free upgrade program is as much about the environment as it is about customer service and technical compatibility. Theoretically, 500,000 mounting kit upgrades means that up to 500,000 perfectly functional CPU coolers were kept out of the e-waste pile, conserving raw materials and cutting down on waste.
