Fan adapter, 90mm auf 60mm, for heat sink, acryl
Use this fan adapter to install a 90mm fan onto a heat sink which normally can only house a 60mm fan. Using a fan with larger diameter has a positive effect upon noise level, as these fans require far lower rotational speeds for the same air flow volume. Fan adapter made from transparent acryl and offers excellent price-performance ratio, including several screws and washers.
