Raijintek Orcus 240mm AIO Cooler Review

Raijintek Orcus

With some of the coolest looking and performing coolers on the market, I’m always excited to see what’s next from Raijintek. The continue to deliver extremely competitive, stylish, and surprisingly affordable products, so I’m hoping to see something similar from the Orcus.

The Orcus comes equipped with a 240mm slim form factor radiator and two high-performance Iris RGB LED PWM fan. Furthermore, it uses an “external” pump and a new CPU block design. The pump is located on the tubing, moving it away from the motherboard and radiator to reduce vibrations, which is certainly an interesting approach.


  • Complete water cooling system with easy installation
  • Pre-filled and maintenance-free
  • High cooling performance thanks to 38 mm thick dual-radiator
  • Two Iris 120 mm RGB-LED PWM fans
  • Comes bundled with RGB controller
  • Quiet 25 dB(A) pump
  • Improved compatibility

What Raijintek Had to Say

“ORCUS’s copper water block is a most advanced design of micro channels (0.1mm), extra large contact fin area with multiple channels for the best direct flow of liquid. More than this, ORCUS’s Pump is placed externally which will not incur vibration and stress on M/B and CPU. ORCUS external Pump is designed for high Q-Max, low dBA, and contains a reliable Bearing type.” – Raijintek

Packaging and Accessories

The box is very nicely designed and shows a clear image of the CPU block, radiator, fans and pump.

Around the back, you’ll find the specifications and technical stuff, as well as a few shots of the RGB lighting.

The Orcus really does come with a bit of everything! In the box, you’ll find some top-up fluid, fans, RGB hub and remote control, as well as the Intel and AMD brackets. Of course, you’ll also find the cooler, obviously.

The fans are nicely designed, with a frosted ring and fan blades. Of course, that should allow for the RGB lighting to really make them glow.

The RGB cables all hook into this hub, which is powered by Molex, and can be controlled via your motherboard or the remote. It’s just a lighting hub though, not a fan hub, so keep that in mind.

The control is pretty straightforward too, with all the usual effects and profiles just a press away.
