The advanced design of the SP120 provides the higher static pressure that radiators & heatsinks dem&, while maintaining a quiet noise profile. Seven ultra-wide, custom-molded blades deliver high static pressure, & the customized fan enclosure helps airflow move in the right direction. The rubber mounts & the advanced hydraulic bearing system combine high reliability with low-noise operation. Cooling today's high-performance PCs is a complex task, & a single fan design can't meet every need. The fan you use to exhaust hot air out of your case might not be the best fan to mount flush against a heatsink or radiator. Static pressure is the measure of how well a fan can push air in this type of highly restrictive environment, & this is where the SP120 excels. It's an ideal solution for radiator & heatsink use, as well as drive bay intakes, & other locations where you're mounting a fan directly adjacent to a heat source.
