Prolimatech announced a unique new accessory that makes it easier to attach fans to metal cases, at least those made of steel (and not aluminum). The Magnetic Pin is a conventional rubber fan bolt with a magnet on its head. This allows fans with four of these to snap onto cases' fan frames. The magnet is embedded into a rubber cavity, which dampens vibrations between the fan and the case, minimizing noise. Prolimatech is selling these pins in sets of four. The company did not mention pricing.
