Bykski DDC Pump Reservoir Station 220mm Temp Display 5V ARGB

SKU CH-RM35-6MB4C

A 220 mm reservoir with integrated DDC pump, digital temperature readout and 5 V addressable RGB lighting

  • Product typeCPU Block
  • Real-time loop monitoring with digital temperature readout
  • Quiet 5000 RPM DDC pump delivers 600 L/h flow
  • 5V addressable RGB lighting syncs across the build
  • 220 mm tall PMMA reservoir shows coolant clearly
  • Multiple mounting options include 120 mm bracket and DIY elbows

Pump-reservoir combo with temperature display

This Bykski station integrates a DDC pump, a 220 mm tall PMMA reservoir and a digital temperature read-out in one unit. It suits custom-loop builders who want real-time coolant monitoring and 5 V addressable RGB lighting without separate components. The aluminium cover plates and pump armour add structural rigidity while keeping coolant contact limited to acrylic.

Check G 1/4 thread count and mounting space

The station provides three inlets and one outlet, all G 1/4 in, so verify your fittings match that thread before ordering. A 120 mm mounting bracket and DIY elbow brackets are included, but confirm your case can accommodate the 220 mm height, 81 mm width and 73.8 mm depth. The pump requires a 4-pin PWM header and a 4-pin Molex connector from the power supply.

Thermals, noise and power draw in normal use

Rated at 15 W TDP on a 12 V rail (10–15 V range), the pump spins up to 5000 RPM and delivers 600 L/h flow with a 6 m head. At 4000 RPM the coolant temperature is specified at 45 °C while low-vibration operation keeps acoustic output minimal. MTBF is listed at 50 000 hours.

Questions about this item

Does the 220 mm reservoir station include every bracket needed for a 120 mm fan mount or must I source extra hardware?

The kit ships with a dedicated 120 mm mounting bracket (B-BKT-105) plus DIY elbow brackets, so no additional brackets are required for standard installation.

Should I choose the version with the digital temperature readout and 5 V ARGB or a simpler variant without those features?

This model is the only variant supplied; it integrates both the real-time temperature display and ultra-bright 5 V addressable RGB lighting as standard.

What does the 600 L/h flow-rate figure mean once the pump is running inside a custom loop?

At up to 5000 RPM the DDC pump delivers 600 L/h with a 6 m head, providing strong circulation for typical CPU and GPU blocks while reporting coolant temperature at 45 °C when spinning at 4000 RPM.
