Today we will be taking a look at the latest Raijintek AIO CPU cooler with the ARGB illumination. The cooler is from the EOS series and comes with a large, 360mm radiator recommended for the most demanding of processors. As you know, Intel recently launched their 11th Gen Rocket Lake processors, so for our tests, we will use the Intel Core i7-11700K processor, which is rated to run at 3.6 GHz (5.0 GHz Boost) with a TDP of 125W.

This is our first Raijintek review, so I’m even more curious how the latest AIO CPU coolers from this brand perform. The cooler also has a fresh and unique design, but about that, I will tell you some more on the next pages of this review.

Stay with us to find out how much to offer has the Raijintek EOS 360 RBW CPU cooler.

  • Closer Look, Specification, and Product Photos

 

Raijintek prepared an amazing presentation with installation elements so let’s take a look at the pictures below, including key features of the product.

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

The EOS 360 RBW comes in a typical for this type of coolers, quite large box. The product is also protected similarly to other brands, higher series AIO coolers. The most important is that the product is well-protected and the package contains everything we may need for the installation. The only thing missing compared to some other AIO series with ARGB illumination is an RGB controller. We can find it in Raijintek ORCUS, which will be reviewed soon, but not in the EOS series. I assume that most users don’t use it anyway, but those who don’t have motherboards with ARGB connectors may need it.

Since it’s our first Raijintek AIO cooler review, it’s hard to compare it to earlier products of this brand. We will make a little comparison in the upcoming Raijintek reviews, and I can promise you that some more products will be presented soon.

Used 120mm fans are very quiet and perform well. During tests, we could register up to 1600RPM, while most of the time, fans were spinning at about 800RPM. It’s hard to talk about the noise during a typical work as the ambient sounds were louder during the tests. Counting that, we could register about 32-34dB in a quiet room, then you can count that the cooler was generating lower noise by itself.

The cooler has quite a unique design. Most AIO coolers are designed with the pump built-in CPU block. The EOS 360 RBW has its pump in the radiator. It’s hard to say if it’s a better or worse option. Certainly, it causes that the CPU block is smaller, and at least for me, it looks better. On the other hand, we have to be sure there is enough space in the PC case as the radiator will be longer than the usual 360mm radiators.

The cold plate is made of copper, and it’s well-designed. It’s also using 0.12mm microchannels, and this type of design is right now the best option for CPU coolers.

 

Installation

The installation is quite simple, and everything is well-described in the manual. I actually like the new mounting kit. It fits perfectly on every socket and doesn’t use additional space so that it can be installed on every available motherboard. It also looks good.

If you are a less advanced user, then you can handle the installation without issues, as long as you stick with the user’s manual. All elements fit perfectly, and the lighting is compatible with all popular standards.

The above photos show our test rig with the i7-11700K CPU, ASRock Z590 Extreme motherboard, HyperX Predator RAM, and RX6800XT graphics card from ASRock.

The illumination can be controlled by ASRock software. Even more, if you don’t have a proper motherboard, then some graphics cards, like our RX6800XT, have ARGB connectors so that we can use them for the cooler lighting. The same ASRock software can manage the motherboard and the graphics card and synchronizes most modes with the Raijintek cooler.

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

All tests were performed on the Intel i7-11700K 8-core processor, ASRock Z590 Extreme motherboard, HyperX Predator 16GB DDR4-4600 memory kit, and ASRock RX 6800 XT 16GB graphics card.

There are three tests. The first is 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.

The i7-11700K is a new CPU, and I’m sure that our readers wish to see how popular 360 AIO coolers can handle its heat. The CPU was working at its rated frequency. However, to keep it at the higher frequency for longer, we had to unlock power limits and their duration and set a fixed voltage of 1.30V. The default Intel settings cause the CPU to limit the frequency and voltages, giving hard to compare results. At fully automatic settings, the voltage would go down to around 1V, and the frequency would balance between 3.6GHz and 4.6GHz, depends on many factors. This is how Intel handles the ridiculous heat generated by this processor. Either way, let’s take a look at our test results.

The EOS 360 RBW performs well. If we keep the CPU at automatic settings, we wouldn’t see more than a high 70°C. However, most interested in liquid coolers with 360mm radiators are also thinking about overclocking or at least manual settings with balanced, higher performance and lower noise. Certainly, Raijintek delivers high performance and low noise, which is hard to match by the most popular CPU coolers. The best performing and significantly more expensive coolers are about as good for the i7-11700K CPU.

The EOS 360 RBW could keep our fully-loaded processor at about 92°C. As I mentioned, all that at manual settings. Software like hwinfo64 was showing around 270W when the CPU was loaded with AVX tests. It’s hard to transfer heat from this tiny CPU die. Even though coolers are supposed to handle even 350W+, no popular cooler can keep 265W+ Intel Rocket Lake CPU below 90°C. It’s probably one of the reasons why sales of these processors are not going as Intel planned, and we can already see price drops.

The overclocking wasn’t possible because of higher voltage requirements, above 1.35V, which causes that the CPU is reaching the throttling point, so already 100°C+.

Conclusion and Verdict

Raijintek EOS 360 RBW ARGB cooler delivers high performance, quiet work, and amazing lighting effects. This is everything that gamers and computer enthusiasts expect of a cooler this type.

The cooler’s performance can be compared to top coolers from the competition. It’s also tranquil during a typical work. When fans work at their maximum speed, it will be audible but won’t be loud.

One of the key features is, of course, ARGB illumination. It looks exceptional and can be synchronized with other devices. Raijintek didn’t add an ARGB controller what can be a disadvantage for some users, but most probably won’t care about it.

One of the strongest points of the EOS 360 RBW ARGB is for sure its price. It’s one of the cheapest AIO coolers with a 360mm radiator on the market. The cooler costs around $81 in the Amazon store. This price is hard to beat by any other, competitive cooler.
