Bykski PWM DDC pump, maximum flow 720L/H, maximum head 4.5m, PWM controlled water cooling pump, B-PMS6-NX-X

The Bykski pump/reservoir combo keeps coolant circulating through your custom water cooling loop reliably and quietly. Designed for continuous-duty operation, it maintains consistent flow rates even as loop temperatures rise under sustained GPU inference loads.

24/7 AI workloads demand a pump that runs indefinitely without cavitation or vibration noise. The brushless motor and ceramic bearing are rated for continuous duty — no cycling, no warm-up quirks, no noise spikes under load. PWM speed control lets you tune the balance between flow rate and acoustics.

Fittings: G1/4 thread. Power: 3-pin or 4-pin PWM (varies by model). Ships worldwide.
