Heat has been a major issue in the computer market for several years now, especially with the newest hardware on the market. It is an even bigger issue for overclockers, and for people who live in naturally hot places, i.e. when room temperatures exceed 28C / 83F. In this situation, users need to upgrade their cooling systems to prevent hardware damage. Most users buy fans for their system based on price, but without careful research, an average person is more then likely to fall into the noise trap: the wrong kind of fan will result in a very noisy PC, and users will be forced to spend money on rectifying this problem. At first, this might seem like a dead end for some people, but with Zalman's newly released quiet ZM-F1 80mm, ZM-F2 92mm, and ZM-F3 120mm Fluid Dynamic Bearing fans, as well as Zalman's quiet Shark's Fin Blade Design quiet ZM-SF3 120mm fans, users have finally found fans that ventilate quietly without decreasing performance. Zalman claims that their Fluid Dynamic Bearing have a very quiet motor, and the Shark's Fin Blade Design fans have a blade design that reduces air turbulence without reducing air flow. Let's take a look at how these fans compare to their well known Noctua counterparts.
