If you haven’t yet, I would encourage reading the review of the XSPC X2O 420 single bay res/pump unit. That particular res/pump combo unit uses XSPC’s small profile X2O 420 pump which works pretty well for low-medium restriction loops. As such, I recommended it for small loops, and in particular mITX builds. But with more and more cases opting to not have 5.25″ bays, that particular product was not going to be as useful as possible. Similarly, not everyone likes using bay reservoirs. XSPC decided to make a more tower based version of this using the same X2O 420 pump and thus the Ion was born. Thanks to Paul for providing a sample for review, so we may see if the product delivers all that it claims.

Let’s take a look at the specifications courtesy the product page:


  • Dimensions: 58 x 50 x 154 mm (excluding accessories)
  • Maximum Flow: 420 lph (12 V)
  • Maximum Head Delivery: 2 m
  • Power Connector: 4 Pin Molex
  • Voltage: 12 V (Startup 9 V)
  • Power Consumption: 6 W
  • Noise Level: 35 dBA
  • Coolant Capacity: 84 mL
  • Shell Material: Aluminium
  • Reservoir Material: Acrylic
  • Maximum Temperature: 60 ºC
  • Inlets: 2 x G1/4”
  • Outlet: 1 x G1/4”
  • Fill Cap: 1 x M20

Please note that this is not a cylinder style reservoir, but rather cuboidal in shape. But functionally it is no different than a cylinder res/pump combo with fill port on the top and inlet/outlet ports on the body. It uses the same X2O 420 pump we saw in the review linked above, and the rated specs for the pump are identical here. XSPC has a scaling drawing online for those wanting to know more than just the 58 x 50 x 154 mm size of the unit, which is quite small as it is, and will help plan where and how to install this in a case. The Ion follows the same design scheme as their AX series of radiators and has an aluminum shell around the actual acrylic reservoir and pump itself. As with other XSPC products, there is a 1 year limited warranty on this which I would have liked to see increased to 2 or even 3 years myself. Let’s take a good look at the Ion on the next page.
