With Zalmans technology, the FX100 is designed to utilize natural convection where the heatsink passively transfers the heat to the surrounding. The hot air is then exhausted out of the chassis with the help of chassis fans. &, due to its passive & efficient operation, several factors that contribute shorter life span in electronics (such as vibration, dust, & heat) have minimal impact, which makes the FX100 one of the most durable CPU cooler out in the market.
