The FHP141 is an exceptionally high performing 140mm fan designed for cooling CPU heatsinks. It has steeply raked fan blades thanks to its thick, 38mm profile, which enables the FHP141 to achieve not only high airflow but very high air pressure for its size. An integrated switch provides users with the option of running the fan in either power mode (500 ~ 2000rpm) or quiet mode (500 ~ 1200rpm) via PWM fan headers.
