- This NZXT 140 mm fan is perfect for high-end setups, thanks to its 1700 rpm speed - It's PWM controlled so it'll adjust the speed based on the temperature of your hardware - The tight frame design pushes more air through with less noise, so you get serious airflow without the annoying hum- The fluid dynamic bearings keep things running smooth and quiet for up to 60,000 hours, so it's built to last- Thick blades are made for high static pressure—great for radiators and tight spots
