XD5 RGB Cylinder Reservoir with D5 Pump

Corsair HydroX Custom Liquid Cooling Review 18 |

The first reservoir and the one we will be using in the build is the XD5 RGB. This is a cylinder style reservoir, although this one is more squared off with flatter sides creating a unique aesthetic for the finished unit. The packaging, as expected, is taken over by the image of the unit with the descriptor portion across the bottom.

The box, as we saw in the previous image, had a split running horizontally across the middle, which allows it to open like a clamshell. When opened, we see here that the mounting brackets are visible along with the manual and other accessories below it.

Pulling the second covering layer and brackets out of the way reveals the pump/reservoir unit itself. Also, here is another bracket option for mounting, which is the one we will use to mount in the PSU chamber of our 680X.

Here we have the first pair of accessory parts. Firstly, it is the fasteners which consist of screws for mounting several different styles, from fan or fan opening mounts. We also have the knurled thumbscrews for mounting directly to the rubber insulated mounts on the pump/reservoir bottom mounts.

Next up is the mounts themselves, which has a 140mm fan mount, a 120mm mount, and the central unit which the pump slides into. This bracket allows you to direct mount to appropriate holes in a chassis or the fan mounts depending upon your needs. There is also a 24-pin jumper included, which will enable you to switch on the PSU without the system operating for leak testing without board and GPU components powered on.

Another addition to the reservoirs for Corsair is a water temperature sensor. This can plug into a motherboard header, such as those on the ROG board we are using, or we can connect to the Corsair Commander Pro, which is what we opted for.

The two paper additions to the kit are the XD5 RGB manual, which is a multi-page booklet, and the warranty pamphlet, which covers the warranty for the component.

Here we take a look at the ports on the XD5 RGB, and there is four total. The XD5 has one outlet for the pump, while the other three can be used for inlets or the thermal probe. I opted to use the two ports side by side for inlet and outlet while the others were plugged with a stop plug in one and the thermal probe in the other.

Inside the base, above the pump, we see that there is a form of anti-cavitation grille in place which has a unique angular design. The middle above the pump inlet is the Corsair logo cut out of the plastic grille.

Peeking at the bottom of the pump, we see the label on the D5 model, which shows it with a max of 30W and 10bar pressure. The unit is PWM controlled so that the pump speed will vary based on the PWM/controller input.

Looking at the top of the XD5 RGB, we first have the top ports. The two top G1/4 ports can be used for various things, one has a tube running into the reservoir area and would be best served as an inlet if you opt to have your return line for the loop come in through the top. Both can be used to fill; however, it is better to use the non-tube port as the tube one will stop filling once the liquid level reaches the tube unless you uncap the other port as well.

Looking at the top cap from underneath, you can see the addressable RGB LEDs. These are downward-firing, illuminating the walls of the reservoir along with the liquid within. These are individually addressable and controllable via iCUE.

The connectors for the XD5 RGB are split into two groups. The first being the pump controls, which consist of a PATA connector for power, which has only two pins for +12V and ground. The other is a 4-pin fan header with only two pins inserted. The two pins are for RPM sense and the other for PWM signaling. When combined with a motherboard PWM header or even the Commander Pro, we can control a precise curve for the D5 pump to give the best performance and noise profile.

The top cap is up next, and this is the RGB wiring, which we opted to plug into the Commander Pro. This is a daisy chain style as you see one male, and one female connection. This allows us to connect all the liquid cooling parts in line with each other.
