EK-Loop VTX PWM Motor is a custom loop water pump with power management control (via PWM - pulse width modulation) of rotation speed through motherboard BIOS or a dedicated fan controller. 
 

These VTX pumps, which are already featured in pump-reservoir combos, boast a DDC-compatible mount, remarkable head pressure, and efficient flow rates in a small footprint – making them ideal for smaller cases. The pumps can be used with all reservoirs and distribution plates compatible with DDC pumps, providing an alternative option. 

Despite a remarkably small footprint, it has up to 5,3m of head pressure. This is more than adequate for most loops, aside from those featuring 4+ GPUs and lots of QDCs. With the maximum flow rate of 1100L/h, it is sure to provide an ample flow of coolant inside the loop.

The VTX pump is water-lubricated and must not be run dry to prevent permanent bearing damage from occurring. It uses a 4-pin Molex for power and a 4-pin PWM fan header for control and readout.
