Today, we will present to you the Raijintek ORCUS 140 RBW AIO, one of the latest CPU coolers from Raijintek, and it’s also one of the most interesting CPU coolers due to its size and design. It’s not hard to notice, that not many manufacturers offer AIO coolers with 140mm radiators. Yet, Raijintek have decided to do this and offer coolers in many sizes, and sometimes less popular sizes too, so that all users can find something that will meet their demands.

Let’s begin this review with a couple of words from the manufacturer, and later we will focus on the key features of the ORCUS 140 RBW cooler.

ORCUS 140 RBW

ORCUS RBW, RAIJINTEK’s evolution All-In-One liquid cooling CPU cooler, designed in Germany and made in Taiwan. With several years of experience in liquid cooling products and cooperation with global engineers and manufactures, RAIJINTEK’s RD team developed the concepts of most performing AIO CPU liquid cooler and spent years to design one of most user friendly and spot light product for enthusiasts. ORCUS RBW’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 RBW’s Pump is placed externally which will not incur vibration and stress on M/B and CPU. ORCUS RBW external Pump is designed for high Q-Max, low dBA, and contains a reliable Bearing type. Not only a new design pump and water block are used, ORCUS RBW’s radiator is also using high density design fin radiator. ORCUS RBW has led the trend to designing a “Rotating Blade” with most popular ADD LED lighting inside tank, which able to show water flow and indicates the coolant level. More than rotating blade indicator, ORCUS RBW is also designed to be refillable. Furthermore, ORCUS RBW cooling fan system is with a 14025 ADD PWM fan, 8port control hub, and remote controller. With switch function (M/B ; Remote) of controller Hub, either you can connect control hub to M/B ADD header (thus, all cooling system ADD lighting including M/B ADD will be controlled synchronously by M/B), or you can switch to “remote” of control hub if no ADD header on M/B, then all ADD lighting will be controlled by Remote controller. ORCUS RBW is not only one of the best performing All-In-One liquid cooling at the market but it is the most user friendly AIO cooler in the world by the pre-filled liquid, providing extra 100ml coolant for your convenience for refill, which brought to you for the joy of friendly design and the surprisingly efficient performance.

The above table includes full specifications. Nothing is unusual, and many things are close to what we’ve seen in the previous Enermax series. There are some differences, but about that, I will tell you a bit later.

Now let’s take a look at the package and its contents.

 

Package and its Contents

The Orcus RBW cooler arrived in a retail package that is quite a large box but also typical for AIO coolers. As we can see, this package is shared with the version equipped with a 280mm radiator. However, I asked Raijintek for the 140mm version as this size radiator is really rare, while many users may find it just perfect for their exceptional PC.

We will find everything we may need for the installation in the package and even more as there is even a bottle with coolant. The cooler supports all popular sockets, but I won’t hide that the mounting kit is much better for the Raijintek EOS series. The brackets for the Orcus are quite large what makes it impossible to install the cooler on some ITX size motherboards or motherboards, which a backplates/heatsinks on the back of the PCB. As an effect, tests were planned with ASUS Crosshair VIII Impact, but the cooler couldn’t fit, so we used MSI X570 Unify. The same issue was with Enermax AIO coolers tested in the last months.

The used fan is very quiet. In tests, it was spinning at about 1000RPM for most of the time while under the maximum CPU load, it could reach about 1500RPM. The software was reporting about 5400RPM for the pump, which was also very quiet during tests. The pump itself is quite interesting as it’s external and has a small size. It’s rated at 86 L/H, so not much but still enough for this type of cooler.

The CPU block has a built-in tank with a coolant flow indicator. It shows if the water flows and if the tank is full of coolant. Simple and functional.

The water block with a built-in pump is similar to what we could see in the AQUAFUSION series. The main difference makes the top design. We won’t find here fancy mirror effect but what we get looks pretty good, especially in the dark.

The base is made of copper and has the same focused flow technology as the AQUAFUSION series so that we can expect similar performance.

Installation

The installation is simple, and everything is well described in the manual. ARGB illumination works excellent and can be synchronized with other devices. There was no problem managing it via included controller or MSI motherboard software.

The above photos are showing how exceptional the cooler looks. LEDs are bright and give live colors.

On the next page of this review, we will take a closer look at the performance.

Performance

All tests were performed on the AMD Ryzen 9 5900X, one of the more demanding processors on the market. Additional components contain MSI X570 Unify motherboard, HyperX Fury RGB 32GB DDR4-3600 memory kit, and ASRock Phantom Gaming RX6800XT graphics card.

Let’s take a look at the results.

There are three tests. The first is simply called Idle, so an operating system without additional load besides standard processes in the background. The second test is based on the PCMark 10 Extended benchmark, which simulates daily work. The last one is a high CPU load tested with AIDA64 with AVX instructions.

New CPUs are giving us a bit misleading results. As far as in the table you can see the temperature in each test, then it doesn’t mean it tells everything about the performance. We could observe that the Noctua NH-U9S couldn’t keep the CPU clock as high as other coolers, and the CPU frequency was more often going 100-200MHz lower than on other coolers. The CPU tried to balance the heat, voltages, and frequency to keep it below 80° C. The Orcus 140 RBW performed well enough to keep the CPU at its rated frequency with a boost clock up to 4.95GHz. Better results were only on the Noctua NH-D15 cooler on which the CPU could run at about 100MHz higher frequency under higher load.

Another difference is the generated noise. The Orcus 140 RBW, for the most time, could work at not much above the ambient noise, which was 32dB. We could register around 36dB for the test rig during mixed load tests, so about as much as Enermax LIQMAX III, which takes more space. The performance was also about the same as that of the Enermax cooler.

I’m sure that all searching for the liquid cooler with a single 140mm fan will be satisfied. There are not many options on the market, but Raijintek delivers a great cooler with many additional features and is available at a reasonable price.

Conclusion and Verdict

This is my second Raijintek review, and I can say that I’m not disappointed. The Orcus 140 RBW performs well considering its compact size and looks fantastic what is probably a must for the current generation of liquid coolers. Potential users of this product are always demanding, so everything counts, and Raijintek delivers a very competitive product worth its price.

Everything would be perfect if not an issue with the mounting bracket. I wish to see the same mounting kit as on the EOS coolers as it’s simply perfect. Most users won’t have problems with that, but I had to mention it as our readers expect. Besides that, the Orcus cooler is a successful product that will give a lot of fun to its users and can be recommended without hesitation.

The Raijintek Orcus 140 AIO cooler costs around €86 in the Amazon DE store. It’s less than most competitive AIO coolers cost, and considering all advantages, I feel it’s worth the price.

 

Pros:

  • High performance
  • Quiet work
  • Interesting design
  • Amazing RGB effects
  • Reasonable price

Cons:

  • Backplate not compatible with some motherboards
