Despite being a fairly new brand in the AIO liquid cooler market, Raijintek quickly become one of the strong contender its Triton liquid cooler. The Triton 240 and Triton 280 which we’ve previously reviewed, is able to perform just as good as a number of well-known brand i.e Corsair, Cooler Master, Deepcool, etc.

Here we have now is one of the latest liquid CPU cooler from Raijintek, the Orcus 240 that comes with a completely new design. The Orcus 240 comes with a pair of RGB fans which can be synched to your motherboard RGB lighting via the included RGB fan hub, integrated flow indicator in the CPU block, and the pump now positioned at the tube to reduce the vibration and strain to both the motherboard and CPU on the long run.

Without any further ado, let’s find out what kind of performance can we expect from this new AIO liquid CPU coooler from Raijintek.

RaijinTek Orcus 240 AIO (1)

The Raijintek Orcus 240 ships in a completely different packaging compared to its predecessor, the Triton 240. The box is way more minimalist in terms of the presentation, without highlighting any kind of features that is available on the Orcus 240. Though, it’ll be better if Raijintek can consider to include at least the prominent features of the cooler itself at the front of the box.

As we proceed with the unboxing, we can see that arrangement of the product and its included accessories is clearly better than the Triton. Putting back everything into the box is way much easier compared to the Triton, which is almost impossible for most users.

Inside the box, you’ll find the Orcus 240, a pair of RGB fans and other included accessories. The accessories that comes with the Orcus 240 includes a user’s guide, screws and mounting bracket which appears to be the same as the previous Triton, fan extension cables, RGB extension cable, RGB fan hub, lighting control remote and coolant for refill.

Before we move on with the Orcus 240, let’s look at what kind of feature does the RGB fan hub offer. At the side of the fan hub, you’ll find a total of 8 fan headers which is sufficient enough for you to configure a push and pull setup on the Orcus 240. At the bottom of the fan hub, there’s an optional header which you can connect it to the RGB header on your motherboard to sync with its lighting if you decide to flip the dip switch for motherboard RGB lighting.

In case if your motherboard doesn’t support RGB lighting control, you can still control the RGB lighting using the included remote controller. For those of you who aren’t really a big fan of RGB, you can easily disable the lighting for a peace of mind.

Much to our surprise, the Orcus 240 comes with a 27mm thick 240mm radiator which features only 18 fpi. Just so you know, 18 fpi is lower than the average 20 fpi count on most AIO radiator in the market.

Located at the end of the radiator is what appears to be a drain port for maintenance purposes. As Raijintek didn’t specifically mention anything about maintaining the Orcus 240 on your own, we don’t recommend users to perform maintenance on their own.

Moving on to the CPU block, the pump is now separated from the CPU block. Although this is not the first time seeing such approach, but we can see that Raijintek has taken some consideration before going for this approach. Having the pump moved away from the CPU block reduces the strain on both the CPU and motherboard due to vibration on the long run.

A refill port can be seen at the side of the block, which allows you to refill the coolant in case if it ever runs low. The built-in flow indicator is probably our favorite feature on the Orcus 240. This is especially useful to determine if there’s a pump failure or to monitor the level of the coolant.


The test is conducted under ambient temperature of 33°C using the following setup and the GC-PRO thermal paste from Gelid:

We’ve also compared the performance of the Floe Riing 360 against a few selected coolers to see how well does it fare against the picks. In order to see how well can each cooler performs right out of the box, no adjustments has been done to the fan speed throughout the test.

Other than the XSPC Raystom Pro Ion AX240 custom liquid cooling kit, the rest of the coolers remains at an acceptable acoustic level when the CPU is on load. We’ve recorded a consistent 68°C on the Orcus 240 during full load. While we can see a slightly better result than the Cooler Master MasterLiquid ML240L by 2°C, but it’s still no match for the custom cooling kit from XSPC.

The temperature increases in a significant number of at least 10°C on all of our test with different coolers. The Orcus 240 now has a peak load temperature of 84°C, due to the poor performing thermal compound between the CPU die and IHS – it’s a known issue for pretty much every Intel i7-8700K owners. This can be shown as even the best performing custom cooling kit in our list started to show signs of not being able to keep up with the heat output from the CPU.

Final Thoughts

Raijintek actually took a step further to redesign a new liquid cooler instead of slapping RGB lighting to the existing Triton liquid coolers. The RGB fan hub might not be the best looking out there, but it does get the job done. Truth to be told, we’re not exactly a big fan of all the RGB lighting. Yet, there’s no deny that RGB lighting is indeed the current trend and products with RGB lighting seems to be more marketable than those that doesn’t comes with any.

RGB lighting aside, the Orcus 240 is fairly easy to install if you’re familiar with Raijintek’s mounting mechanism. Compared to the Triton 240, the Orcus 240 has a much more approachable design that its predecessor. Other than having its pump moved away from the CPU block to reduce vibration on both CPU and motherboard, the built-in flow indicator which allow users to monitor the flow and coolant level of the liquid cooler is another added plus which is not commonly seen on many mainstream liquid coolers. Our only issue with the Orcus 240 is the cable from the pump, which appears to be too short to reach some of the headers on the motherboard if the radiator is placed too far away from the motherboard.

At the price of RM 389, the Raijintek Orcus 240 is a fairly reasonable option for those who wants a decent performing liquid cooler with RGB lighting that doesn’t break the bank.


  • Good performance
  • Comes with a built-in flow indicator
  • Surprisingly powerful pump despite of its position on the tubing
  • Sleeved tubing improves the aesthetics and reduces evaporation rate of coolant
  • Silent fan and pump operation
  • RGB lighting can be adjusted with included remote controller or synched with motherboard
  • Compatible with both Intel and AMD socket (including the fairly newAM4 socket)
  • Comes with extra bottle of coolant for refill
  • Fairly reasonable price


  • Installation guide never specifically mention the proper orientation of the RGB header for the fan hub
  • Cable for pump is rather short
  • CPU block has to be removed from the system for refilling
