Installing the Orcus 240 is fairly straight forward with a couple of unique twists. Let’s get started.
We begin by attaching the fans to the radiator. Checking with the manual, Raijintek has them set to blow air through the rad rather than pull it. We suspect this is due to the orientation of the RGB ring on the single side of the fans. Attach them with the included screws with wires pointed to what will be the back panel of your case.
Next install the bracket to the motherboard around the CPU beginning with the backplate. The Orcus backplate is a squarish shaped metal frame that has holes for all socket types. Simply find the slots that align with the cutouts on your motherboard (ours is 115x) and place the appropriate screws through the holes. Align the screws with the holes and pass them through. On the other side of your motherboard secure them with the standoffs while first installing a plastic washer on each screw. Finally secure the block mounting bracket to the stand offs with the remaining screws.
You can now install the radiator into the top of the case. Align it with the mounting slots and secure it with the included screws.
Now the block is hanging ready to be installed. Before you do that remember to apply thermal paste to the top of the CPU and remove the protective sticker from the base of the block. The paste should be applied sparingly and spread evenly with the included tool. With one hand press the block onto the top of the CPU. With the other thread the block screws into the bracket and secure fully with a Phillips head screwdriver.
The main hardware is now installed and you are ready to move onto the electrical connections. To start attach the 3-pin power wire from the external pump to the CPU_FAN header on the motherboard.
Moving to the back of the motherboard attach an open molex power adapter from your PSU to the RGB hub to give the hub power. Then plug the three RGB connectors that come with the kit into the hub. Now find a place on the MB tray you can attach the double sided tape from the hub to and secure it to the tray. The fans themselves need separate power from the RGBs, we plugged ours into the fan hub that comes with our Phanteks case giving them full power. With that our Orcus 240 is fully installed.
Raijintek includes drip trays that you can place inside your case to collect any leakage that might come from an under-tightened port screw. You may use them for first time use but definitely use them if you’ve opened either of the ports. Fire your rig up and check that you have leds working in both fans and the block. Additionally make sure you’re getting good flow by checking the meter.
