The 120x120x25mm at the heart of the Tuniq Tower 120 Extreme heatsink spins at 2000RPM by default. The attached fan speed controller can bring that down to 1000RPM if you desire. A standard 3-pin motherboard header provides power. The seven bladed translucent fan is internally illuminated by blue LEDs. There is 47mm clearance below the bottom-most aluminum fin.
