Reeven Okeanos RC-1402 – Test and Review

Reeven Okeanos RC-1402 is one of the latest products and actually the first twin-tower cooler, which makes it the biggest model in the company portfolio. This is a cooler designed to deliver a very attractive structure and to provide extreme performance and a lot of cooling capabilities for all modern processors used with the latest Intel and AMD sockets.

So let us waste no more time and check the package, the additional accessories, the cooler structure and after that perform the tests.

The cooler was provided to me for performing a detailed test and review in a very colourful cubical carton package, painted in black/grey/yellow and white colours. And there is plenty of them all around the box.

On the front side and the top panels there are company logos, big pictures of the product itself, seen from different angles and the name of the model. Also, there is a lot of explanation about the dimensions of the cooler, the materials used so it can be created and the compatibility options of the product.

Of course, the full technical specifications are printed on the back of the box in several languages. Actually, the package is not really big but it is very solid, truly reliable and most of all very attractive. The product arrived in perfect condition, so let’s open the package and check what is inside.

And this is the view, which I got after I opened the package.


The first thing to notice after I sneaked a peak the package were the two massive towers of the cooler with 3 white boxes all around them and all of them tidily placed inside the cubical carton fortress.

The first box in the middle of the cooler is actually holding the additional accessories pack, while the two white boxes on each side of the cooler are the cooling fans extra protected from any physical damage.

And this is the view, which I got after I took all of the parts out of the carton bed.


As always, let’s start checking what is inside the white box made to deliver the additional accessories.



All of the  accessories accompanying the cooler were provided to me separately packed in small nylon bags to ensure that all of the parts will be in perfect condition and most important in full quantity. After I took all of the accessories out of their packages and arranged them for taking some pictures, this is the view I got.


The standard Reeven Okeanos RC-1402 additional accessories pack features:

  1. Black metal back plate required for both Intel and AMD sockets
  2. Silver metal square front plate needed for both Intel and AMD sockets
  3. Silver metal bar made to hold the cooler attached to the front plate needed for both Intel and AMD sockets
  4. A set of four plastic tubes to stay between the motherboard and the front plate
  5. A set of four rubber washers to stay between the motherboard and the back plate.
  6. A set of 4 long bolts which will pass through the back plate and the motherboard to hold the front plate.
  7. A set of 2 short bolts to fasten the metal bar to the front plate.
  8. A set of 4 nuts to fasten the front plate to the 4 long bolts
  9. A set of 4 LGA 2011 screw pillars
  10. A small wrench
  11. Six metal clips to hold up to 3 fans
  12. SSA(Speed Switch Adapter) to lower the noise & RPM rate for the 120mm fan
  13. SSA to lower the noise & RPM rate for the 140mm fan
  14. A thermal compound
  15. Installation manual

In my experience and from what I’ve previously seen with other coolers part of the company portfolio, the accessories pack is rich enough to provide a lot of possibilities and to be compatible with all modern sockets and processors. Apart from that, all of the major installation accessories are actually made of solid metal, which will definitely deliver solid connection between the processor and the cooler and trustworthy performance.

Pretty extensive package content I should say and I believe it is time to make things more interesting and check the cooler’s structure.


Reeven Okeanos RC-1402 HEAT SINK STRUCTURE

After I took the cooler out of the package for the first time I spent some time examining the structure and according to what I saw I could say that it offers pretty standard structure with some performance enhancements and is made of the three common components which I am going to check one by one in this review. The cooler itself is designed as a twin tower cooler featuring two very stylish and at the same time pretty thin towers, the two types of cooling fans and the mounting kit.

First things first, so let’s start with the contact plate since it always has the most important role for keeping every processor running cool and most of all stable.

The contact plate The heatpipes
IMG_0272 IMG_0270


Reeven Okeanos RC-1402 is equipped with a perfectly milled contact plate with dimensions of 40 x 45 mm made of copper holding in line the outer 4 x Ø6mm and inner 2 x Ø8mm U-shaped copper heat pipes, which are symmetrical to the contact plate. Both the contact plate and the two types of heatpipes are soldiered together and nicely finished with a very shiny mirror-like nickel coating in silver.

And with these contact plate dimensions the cooler is definitely made to provide compatibility even Intel 2011 models and AMD FX models, which offer the largest DIE architecture.

Enough for the pipes, so let’s check the fin stacks.


Reeven Okeanos RC-1402 is made as a twin tower heat sink with tower structures which are absolutely identically symmetrical to the contact plate and are with dimensions of 120 mm (H) x 140 mm (W) x 40 mm (D) each and overall dimensions of the radiator of 163 mm (H) x 140 mm (W) x 135 mm (D) and weight of 1145g including the fans.

Every tower of the cooler offers 57 pieces of 1mm thick aluminum fins with 2 mm fin gap. Very typical for the company is that the top of the fin stacks, and in this case the 58th fin, which is 2mm thick is not only for performance but is also used to hold the engraved Reeven logo and boost the overall appearance of the cooler by covering and hiding the heatpipes. As usual, thick fins with big fin gaps will require not very powerful but very quiet fans to keep the product delivering stable and reliable performance.

And by mentioning the fans let’s talk about them.


Reeven Okeanos RC-1402 standard setup is made to operate with Coldwing 12 installed on the front tower and Coldwing 14 fan installed between the two stacks. Both of the fans are made to deliver:

  1. Coldwing 12 featuring a square 120 x 120 x 25mm black frame and yellow propeller designed with 11 very narrow and very sharply angled blades made to provide the best possible airflow, static level and noise level balance. The fan itself is made to operate at 300~1800 revolutions per minute range, delivering airflow level of 16.6~92.5 CFM, static level pressure of 0.003~0.098inch H2O at noise level of 4.0~33.4dBA.
  2. Coldwing 14 designed as a round 140 x 420 x 25mm black frame and yellow propeller featuring 9 narrow and very sharply angled blades. The fan itself is made to operate at 300~1700 revolutions per minute range, delivering airflow level of 16.3~92.4 CFM, static level pressure of 0.002~0.091inch H2O at noise level of 5.8~36.4dBA.

Now let’s install the fans and prepare the cooler for testing.

To install the fans I just had to place the Coldwing 14 between the two stacks and the Coldwing 12 on the front stack and then just secure them with the four metal brackets provided in the accessories pack.

And this is what the cooler looks like with the fans installed.

And here I want to mention that both of the fans are directly installed on the fin stacks without any rubber pads to reduce the vibrations and remove every possible noise. Also in the accessories pack there are 2 additional fan clips for installing a third fan on the back of the cooler.


The powering and the regulation method for this cooler is done by directly connecting the 2 fans to 2 fan headers on the motherboard. Something that is not really the best idea because all modern cases provide slots for a lot of fans, which have to be powered too. And here I found that the cooler is not supplied with Y-PWM splitter so the fans could be connected directly to the CPU fan header but every single one of the fans is provided with a voltage reducing adapter. Of course, both of them are marked with a small label to inform which adapter is for which fan.

When both of the fans are attached to the radiator the overall dimensions of the cooler are pretty serious and I am sure that everything around the socket will be covered by the cooler and that includes the memories too. And here I want to mention that if the motherboard is working with low-profile or normal DRAM memory modules the cooler is compatible but the front fan should be lifted a bit over the memories. Unfortunately, if taller memories are used, the front fan will be almost impossible to be attached.

And since I started talking about installation, let’s continue the article by preparing the mounting kit.

According to the official details provided on the company web page, the cooler uses the same backplate and is compatible with all modern sockets:

  1. Intel sockets: LGA 115x / 1366 / 2011
  2. AMD sockets: AM2(+) / AM3(+) / FM1 / FM2(+)

To do the tests I will use the AMD brackets and these are the parts needed so the cooler can be installed on my motherboard:


As always, the first thing to do is to read the installation instructions carefully and pick up the right mounting parts for the actual socket and then to prepare the installation kit before attaching it to the motherboard.


The next step of preparing the mounting kit is to place the 4 long bolts through the backplate holes meant for AMD sockets and later add the rubber washers on the side that will be contacting with the back of the motherboard.

Preparing the mounting kit The backplate ready

After placing the backplate behind the motherboard I installed the four plastic tubes on the front and on top of them the square metal front plate, which was secured by the 4 nuts. Of course, to do so I had to use the small wrench provided in the package.

And of course, the last step was to add thermal compound and secure the heat sink to the processor with the metal bar and the two short bolts.

And this is what the cooler looks like installed on the motherboard:

As you can see from the pictures above, with the heatsink installed on the motherboard it is not possible for memories with taller heat spreaders to be used without removing the front fan, since this is a very massive cooler which when installed is above the RAM slots and most of the elements around the socket.

And this is what the cooler looks like installed on the motherboard and inside the case ready for testing.


The cooler is just massive and fits in perfectly with the black interior of my SilverStone Raven RV03 case.


Reeven Okeanos RC-1402 TESTS

Since the cooler is installed I believe it is time to check my testing rig and continue the article with the tests…

CPU: AMD Vishera FX-8350

  1. At standard frequency 4.020 MHz (at 1.356V)
  2. At low overclock frequency of 4.220 MHz  (at 1.380V)
  3. At medium overclock frequency of 4.420 MHz (at 1.416V)

Motherboard: GigaByte 990FXA-UD3

Case: SilverStone Raven RV-03

Power supply: Antec HCP-750W

Cooler: Reeven Okeanos RC-1402

Thermal paste: Noctua NT-H1 thermal compound

For this test and review I am going to use the two standard Coldwing 12 and Coldwing 14 fans working at full speed of around 1700 revolutions per minute, providing airflow level of 92.5CFM, at noise level of 35dBA in push-pull setup.

The tests will be conducted in a closed system with:

  1. 2 x SilverStone AP181 – 180mm fans on the bottom panel of the case putting fresh air in and spinning at about 1200 rpm
  2. 120mm fan behind the motherboard cooling the socket and spinning at about 1000 rpm.
  3. Room temperature of about 19 degrees.

Both SilverStone AP181 – 180mm fans were connected together to the chassis 1 connector and were rotating at maximum speed.

And here I want to describe my testing method.

I will install Reeven Okeanos RC-1402 and do stress tests using Prime95 AVX software with constant load on the cooler for 14:30 minutes with custom settings of minimum FFT size (in K of 128), max FFT size (in K of 128) and Run FFTs in place at:

  1. standard frequency of 4.020 GHz (at 1.356V), at low overclock frequency of 4.220 GHz (at 1.380V) and  at medium overclock frequency of 4.420 GHz (at 1.416V) using only the Coldwing 14 fan installed between the two towers of the cooler working at maximum speed.
  2. standard frequency of 4.020 GHz (at 1.356V), at low overclock frequency of 4.220 GHz (at 1.380V) and at medium overclock frequency of 4.420 GHz (at 1.416V) with both fans installed on the cooler working at maximum speed.

Now let’s check out the test results:

And the fans speed during the tests:

Results R

I believe it is about time to share my conclusions regarding the product.



1. Okeanos RC-1402 performance:

After I am done reviewing and testing Reeven Okeanos RC-1402 I can say that it is definitely a very serious product made with a lot of smart thinking and meant to provide a lot of cooling options.

The cooler itself is just a massive structure made of very high quality materials such as copper contact plate and heatpipes nicely finished with shiny nickel coating, aluminum fins and durable plastic fans, which when combined delivers amazing cooling performance.

Through the test I was not able to believe the temperatures at which my processor was working at this load but seems Reeven did a good job and created a product which can maintain astonishing cooling performance. And according to what I’ve seen I believe that the cooler is capable of keeping every modern low, middle or high grade processor working at even extreme load without any problem. It will definitely handle to keep the processor working cool and stable. Of course, for extreme performance it will be a little noisy but no one could expect less.

Apart from that after I finished testing the product and set both of the fans working with automatic regulation, connected through additional Y-PWM splitter directly to my CPU header it was pretty quiet since the processor is not getting warmer. 

The only thing that I didn’t like at all is the lack of Y-PWM splitter, which could be very inconvenient if this cooler is installed in a case with a lot of fans and no spare fan headers. But of course with the provided SSA adapters for both of the fans they could be connected directly to the PSU and will work at stable revolutions per minute.

Overall, my impression is for an amazing product, which is meant to deliver outstanding cooling performance at low noise level.

2. Okeanos RC-1402 appearance:

Reeven Okeanos RC-1402 is a product made not only to provide great performance but also to deliver very attractive and eye-catching appearance. Yes indeed, with its silver/black/yellow colour scheme it is not the best choice to be installed in every case with red or blue interior, for example, but somehow the product looks very nice inside black or will look even better in cases with yellow interior.  The cooler is definitely a product which will attract the attention inside a case with acrylic window or modding project.

According to my review, I think that Reeven Okeanos RC-1402 deserves the following reward:


Official price (MSRP) for Okeanos RC-1402: 68 euro

Official warranty: 24 months

I thank Reeven for the sample!
