I have been testing out a lot of watercooling parts lately, and most of them happen to be those that the general public wants to know more about. As such, sometimes products slip through the cracks which may have benefited a lot of people and this may just be one of those. XSPC somehow manages to have watercooling kits at prices that make me question my math at times, and that’s with the more popular Laing pumps. Today we get to take a look at their newest option for those constrained on space, and also budget- the X20 420 pump. This comes currently as part as a single bay res option, and also in a twin pump format with the pumps in series (in the same bay res). But XSPC has announced plans to have an even more compact res/pump option called the Ion. A big thanks to Paul from XSPC for providing a sample of the X20 420 bay reservoir model for testing.

Let’s begin by taking a look at the specifications from the product page:


  • Dimensions:149 x 42.5 x 79mm
  • Capacity: 105ml 
  • Material: Clear Acrylic


  • 4 Pin Molex
  • Maximum Flow: 420 lph (12V)
  • Maximum Head Delivery: 2m
  • Voltage: 12V
  • Startup Voltage: 9V
  • Power Consumption: 6W
  • Noise level: 35dBA
  • Maximum Temperature: 60C
  • Dimensions: 66.5 x 40 x 40 mm

Supplied with black faceplate, 4x M3 x 4mm screws, G1/4″ Plug, and blue LED

This is a single slot bay res/pump combo unit occupying a standard 5.25″ bay in a chassis. The reservoir is clear acrylic and comes with an aluminum faceplate in the front as we will see soon. The pump is plug and play here, with a single full size MOLEX connector for power and nothing else. You don’t get to monitor the pump speed, or control it any which way as-is. There are some devices that provide voltage controlled MOLEX outputs but I would not recommend them here. With a max pressure head of 2 meters (~2.85 PSI) and a max flow rate of 420 liters/hour (~1.54 GPM), you want to get as much out of the pump as possible. XSPC claims a power consumption of 6 W, and a noise level of 35 dBA but we will see soon how it holds up during testing. As with most pumps, it is rated to operate up to 60 ºC and I dare say if your loop hits that temperature then there is something wrong as it is. In terms of dimensions, it is longer than a Laing DDC is shorter in all other dimensions- especially once you have a heatsink on it. It also occupies a smaller volume compared to the D5, and this is one of the main reasons the upcoming Ion is so much smaller than most cylinder res/pump units. But enough of this, let’s take a look at the product now on the next page.
