Raijintek Adios, Themis And Ereboss CPU Cooler Review


It is forgivable that you haven't heard of Raijintek before, however they are claiming that you will hear a lot more about them in the future. The business has been founded by some of the former employees of the well known brands Cooler Master and Xigmatek, which ultimately means that they have a great deal of knowledge and experience into the cooling market already. OverclockersUK picked up on Raijintek with them having them on sale first who have a massive customer base so they are aiding Raijintek to expand their market straight away. Raijintek has such a great management history but is still an 'unknown' brand.

The packaging on these products doesn't really differ, they all feature a common red and grey livery. On the front of the box, there is of course and image of the cooler, and you get more information on the cooler on the sides and rear. Inside the box we find the accessories that are required for the installation of these coolers. The accessories are standard across all 3 coolers as they all incorporate the same mounting mechanism. The only real problem is that the thermal paste is installed in a sachet rather than a syringe which can make it an annoyance to apply.

Raijintek Aidos 92mm CPU Cooler

The adios is the smallest cooler in the range (92mm) with a price of £14.99. The adios has a compact size meaning it can fit to most cases/boards considering it has it's own mounting bracket.

The Raijintek Adios

This cooler goes with the standard tower design, it has a single fan blowing over the fins. They clearly haven't concentrated on the aesthetic design of the cooler as the cooper heatpipes aren't nickel plated so they don't match the aluminium fins. The four U-shaped heatpipes, each with a diameter of 6mm, should transfer a good amount of heat. They have opted for the direct contact design here meaning they have direct contact with the CPU in the block. The fan included is a 92mm Raijintek branded model which has a rather unusual and unique color scheme of white and red. The housing on the fan is red with the blades being white. This doesn't appear to make sense to us as it doesn't match many other components on the market. The fan can spin itself up to 2,400RPM but it is PWM controlled so it can spin as low as 1000 RPM provided that the CPU is experiencing heavy load. It connects to the motherboard using a standard 4-pin fan header.

Raijintek Themis 120mm CPU Cooler

The themis is a slim type 120mm cooler with a price of £21.95. This makes an ideal cooler for most ATX chassis. With the anti-vibration rubbers and supporting all sockets, it is the ultimate choice at a budget price.

The Raijintek Themis

The Themis is the next step up in terms of size in Raijintek's range. It is designed for the users who are looking for that extra bit of cooling performance for their system. The Themis once again carries that tower design with an all aluminium heat sink arranged across the heatpipes. But again the aesthetics haven't had anything to enhance them, meaning the copper heatpipes are left exposed. The themis' 8mm heatpipes are slightly larger than the Aidos however there are only 3 this time. They once again feature the direct-contact design. The fan this time is once again Rajintek themed with a color scheme that is hard to find other components in, however this fan is a 120mm version which is free to spin between 1000RPM and 1800RPM controlled by PWM and it depends on what temperature the CPU is running at.

Raijintek Ereboss 140mm CPU Cooler

The Ereboss is the flagship cooler of Raijintek's current range (140mm) with a price of £31.99. It also includes the worlds top slim type 14013 fan. The Ereboss is designed to provide an awesome performance with a great price. While the fan is only 13mm thick it still provides outstanding performance.


  • Nickel copper base, efficient 6mm Heat-pipe (x6) & a rather large dissipating area fin
  • Super Slim type 14013 PWM fan - 13mm height; Low noise & outstanding air flow as well as pressure
  • Multiple mounting kits for a wide range of sockets
  • Patent designed holes on fins to provide excellent air flow and cooling efficiency
  • Ability to use dual fans and anti-vibration rubber attached.


  • Dimension: 140mm (W) x 110.5mm (D) x 160mm (H)
  • Base Material: Nickel Copper
  • Fin Material: Aluminium Alloy; Solder-free fins assembly
  • Heat pipe: 6 pipes
  • Fan Dimension: 140mm (W) x 150mm (H) x 13mm (D)
  • Voltage Rating: 12V
  • Starting Voltage: 7V
  • Speed: 1100 ~ 1650 R.P.M
  • Bearing Type: Sleeve Bearing
  • Air Flow: 66.65 CFM (Max)
  • Air Pressure: 1.72 mmH2O (Max)


The Raijintek Ereboss (upside down)

Being Raijintek's current flagship model the Ereboss is significantly larger than the Themis and is aimed at those users who are looking to achieve a fairly large overclock on their system. Just like it's counterparts the Ereboss features the tower design. The heatsink is once again arranged the heatpipes, however the Ereboss has six of them rather than the three. The six 6mm heatpipes should in theory provide twice the area to dissipate heat than the three in the Adios. But the heatpipes here aren't direct contact, as the CPU block here incases them and it is entirely nickel-plated. Despite the Ereboss being a single tower design, it has a massive surface area for heat dissipation as the individual aluminum fins are very large. The fan that comes with the Ereboss is a rather strange choice. While the 140mm aspect of the fan seems normal, however it is only 13mm thick. This puts it about half the thickness of a standard 140mm fan. It is remain to be seen as to whether this will affect performance at all. The fan itself is once again red and white in color. It is also PWM controlled and is able to spin between 1100 R.P.M and 1650 R.P.M. It also features a 4-pin PWM connect just like the other two fans. It would be nice too see a two fan variant in the future with this cooler as it is positioned as being a high-end model.

Final Thoughts

The Raijintek coolers are there to make a very strong first impression providing a bang-for-buck deal, as they offer decent performance at competitive prices points. This range appears to be have positioned to directly compete with the likes of Cooler Master and Xigmatek. They all utilize a single tower design which does keep them out of the top end of the market but this is a good thing as it is becoming increasingly crowded. The color scheme of the fans seems to be the only problem as there aren't many other components that are red and white. At this current point in time the coolers are only available for pre-order on Overclockers UK here. The prices make all the coolers a good value for money; with the Adios being priced at £14.99, the Themis at £21.95 and the Ereboss at £31.99. The Adios would be the best option if you are looking to build a powerful system in a fairly compact case. In the future it would be nice to see Raijintek release other components that follow this color scheme such as case fans or some cases themselves.

Interesting, can you provide links to that exact item? They seem to have quite a lot of these.


Also, do you know if they will ship to the US/take US currency? (Even if they won't take USD, just means I'd have to use PayPal instead of directly using a credit/debit card.)
