Introduction, Specifications, and Pricing
So far, our only experience with Reeven has been with the Ouranos single tower CPU cooler we recently reviewed. In regards to that experience, we will say that the time we have spent with Reeven products has been completely positive thus far. We learned that Reeven is very aware of the current market and its offerings, and has come up with a cooler that is very capable of holding its own in the fight for the top of our charts. We also learned that their coolers feature a very beefy, structurally solid design that definitely lends that top-tier feel to their products. Another thing we learned is that if you do like the looks and performance of a Reeven cooler, you will need to like the color yellow, because yellow appears to be their trademark color, as their fans brightly show.
As we just mentioned, our first experience with Reeven products was when we reviewed the Ouranos. Even though that design is prepped for two fans, it ships with a single fan, and its design is roughly based on the typical, tower style cooler design. While Reeven proves to hold their own in the standard tower cooler segment, they are also trying their hand at a dual-tower design. This means a few things right out of the gate. First, there are two fans in this kit, one to cool each tower. Secondly, the footprint increases as space and access around the cooler diminish. And lastly, one can only assume that with twice the fan, more surface area in total, we should also see a healthy performance jump over the Ouranos.
When we received the Ouranos from Reeven, we also received the cooler we will be testing today, the Okeanos RC-1402. While we covered most of the standout features offered in this cooler already, like the two bright yellow fans, a dual tower design, and its larger foot print, the Okeanos still has a couple of things left in its feature set. For instance, while the Okeanos is definitely not the same cooler as the Ouranos, the relationship between the designs is apparent in the trim and aesthetics.
Enough talking about the Okeanos though. Why don't we just get right into the specifications, so we know exactly what we are dealing with? Let's get a good look at the Okeanos RC-1402, and see what Reeven is offering this time around.
In the specifications chart offered by Reeven, we see that the Okeanos is indeed the RC-1402, it is compatible with all current Intel sockets, and it works with anything AMD since AM2. We are shown the overall dimensions of the Okeanos, including its 1145 grams of weight, 140mm of width, 163mm of height, and the 135mm from the front edge of the intake fan to the back edge of the second fin stack.
What Reeven doesn't mention is that both towers are topped with a one millimeter thick, brushed aluminum plate sporting the Reeven name. Reeven also doesn't tell us that these stacks consist of fifty-seven aluminum fins, which are 0.3mm in thickness, and are pressed onto the heat pipes. Here we are given some information on the heat pipes; the chart states that we get four 6mm heat pipes, and two 8mm heat pipes in the center. Of course, these are made of copper, but are also nickel-plated to add aesthetic appeal, and to help fight corrosion. The two-part base is also made of copper, and is nickel-plated along with the pipes; after they have been soldered in place, of course.
There is quite a bit of information to read about Reeven's choice of fans. In the box, you will find the 120mm, RM1225S18B-P, sleeve bearing fan used as the front fan. This fan is specified to spin in a speed range of 300 to 1800 RPM, delivering 92.5 CFM. As for the air pressure, we think we may have a handle on the information given. If our math and concept are correct, after converting the 0.098 inches to millimeters by multiplying it with 25.4, the 120mm fan should have 2.48 mmH2O. The 140mm fan for the middle of the towers is the RM1425S17B-P. This fan will spin in the range of 300 to 1700 RPMs, delivering 92.4 CFM of air flow. With that same math in play, our figures come up to 2.31 mmH2O of static pressure, making both fans almost a dead match outside of their dimensions.
Similar to what we saw with the Ouranos, finding the Okeanos cooler inside of the U.S. is nearly impossible, they just are not listed unless you happen upon a review sample on eBay, or similar websites. In our email correspondence with Reeven, we received the projected pricing for when the Reeven coolers do arrive on our soil. We are lead to believe that the Okeanos RC-1402 will sell in the range of $75 to $80. Think about that for a moment, and consider the release pricing of other dual-tower coolers. Just looking back at coolers like the Noctua NH-D14 and D15, or the likes of the Dark Rock Pro 3 and Assassin, these are all coolers that will cost much closer to the $100 range. If this Reeven is able to keep pace with the other dual-towers, that near $20 in savings will send the bang for the buck value of the Okeanos through the roof.
Reeven tells us "Don' think, feel it." just above the large image of the Okeanos that stands front and center on the packaging. In the black stripe at the bottom, we read that this is a dual radiator design, it is built with six nickel-plated heat pipes, it offers unique mounting hardware, and it offers in-line adapters for the fans.
After spinning the box around, we now get a view of the Okeanos RC-1402 naming at the top, and an image of a slightly different angle of the cooler. This time, the black stripe shows that there are two fans in the box, and gives another mention of the dual radiator design and nickel-plating, but this time, both have images showing where to find them.
On the back, in the gold band up top, we see that the Okeanos RC-1402 is made in Taiwan. The bulk of the panel offers the multilingual specifications chart, and that black band offers the Reeven company and website information.
This last panel starts off at the top by showing this cooler's socket compatibility. The panel then offers two renderings of the cooler with its dimensions clearly shown below and to the right. At the bottom, that black band now offers precautions to help ensure the proper use, and installation of this cooler.
Inside of the box, we find things packed for transit in a layered effect. On the left there is a box containing the 120mm fan, and then we run into the first tower of the cooler, which is kept in the center of the box. The hardware is in the box between the towers, then the second section of the cooler, and the last box at the right is where the 140mm fan is located.
With multiple layers of cardboard and the hardware to keep the towers parallel, the only oddity is the lower fins are slightly upwardly bent; the rest of the cooler, as well as the box's contents, all arrived in great shape.
Reeven Okeanos RC-1402 CPU Cooler
Starting out with the top of the Okeanos, this time we see that there are in fact two identical fin stacks in this design. Once all of the fins are pressed on, a thicker aluminium plate is applied, one in either orientation, so that the Reeven name is easily read in any orientation.
Putting the Okeanos in its upright position, and looking across the front of the fin stack, we get a good idea of how the heat pipes run through the fins. We also get a good sense of the heat pipe configuration, which poses the thicker pipes in the middle, and two thinner ones on either side to help offset the load.
As we get the profile view of the Okeanos, we can see there isn't any offset in the pipes that would allow us to say one orientation is correct over another. In this design, the cooler is evenly distributed to either side of the base, so the cross bracket can evenly support it against the socket.
While the edges of the fins are cut flat, we can see that there are peaks and valleys cut into the fins to take advantage of the way most fans distribute air flow. It is lowest near the center to allow the fan to build up some pressure first, and near the edges it is higher, as less heat travels that far to the edges.
Looking up at this side of the Okeanos, we also see the center of the sides of these towers have been cut away. While it does very little for efficiency, it does add another angle to view from the top.
To fully see how the heat pipes are configured, we took the time to snap this image. The center pipes take on most of the work, running through the center of the cooler where most of the air flow is concentrated. As for the thinner pipes, they run out wide, and are much closer to the outer edges.
After removing the protective plastic cover for the base, we grabbed a thumbscrew, and set it on the base to show the finish. While it appears to be nearly a mirror in its reflection, looking closer shows the faintest trace of very fine milling marks. The center of the base is slightly convex, and does not deflect until way outside of the contact area.
Grabbing the fans, and following the instructions, we put the 120mm on the front of the Okeanos with the 140mm fan in the middle.
Looking from the side with the fans now in place, it is easier to see how the smaller fan affords more room where it is needed most. As for the center 140mm fan, it does sit very low in the cooler, and will not raise the overall height of the cooler. It will also supply a good amount of air right near the power delivery systems on the motherboard.
Accessories and Documentation
The hardware kit that comes with the Okeanos is very similar to what we found with the Ouranos, with a few additions. Here we see the wrench that works on the top bracket nuts, which are shown to the right of the wrench. This wrench can also be used for the cross bracket screws shown below it. We find the backplate studs in the middle, and the LGA2011 hardware to the right as well.
We also find a universal AMD and Intel backplate that is not isolated on its own; it is just black painted steel. On the right are white spacers for the top of the board, and four rubber washers to surround the studs, and isolate the backplate. We also get a LGA775 preload spacer to stick to the plate, and a plastic bag of thermal paste.
Once the back plate is installed, and the spacers are on the studs, the next step is to add this universal top bracket. It will go on in both directions for AMD, as well as Intel users. Once this bracket is secured, you take the cross bracket at the top, set it in the base of the cooler, and mount it to the larger top bracket.
We also found the box contains a voltage limiter to keep the 140mm fan running at 1100 RPM, and an installation manual that is detailed enough to get anyone through the process. To the right we find the Okeanos ships with six wire fan clips, so it is prepared to run with three fans if that is desired, and we also find a limiter to keep the 120mm fan at 1200 RPM.
We made sure to get a look at the fans that come with the Okeanos. To the left is a 140mm fan, powered with a four-pin connection at the end of a sleeved cable; this fan offers a black frame, and nine large yellow blades. The 120mm fan offers the same features, but has eleven smaller blades so that it can keep up with the 140mm fan, and share almost identical capabilities.
Installation and Finished Product
To get things properly installed, we start at the beginning, aligning the studs with the keys cut in the holes of the plate. Then, we simply press the washer down over it to hold it into place, and isolate things from the motherboard.
The next thing to do is to grab the backplate with the studs securely in place, and drop it through the holes in the motherboard. We also see that the plate is trimmed to allow it to go in any orientation for Intel sockets.
To get here we slid the white spacers on, and installed the bracket to allow the towers to run vertically. The nice thing about this plate is that it does allow the cooler to be installed horizontally in orientation as well. This option works in favor of AMD users, and those instances like this where the cooler is too wide to clear our armor covering.
This is exactly why these next few images will look a bit off. Luckily for us, the Okeanos has no issues with this orientation. For purposes of the images, we installed the fans this way, but air flow was reversed for testing. In the proper orientation, we would have been able to keep the tip on the memory, but this way, the stacks do cause clearance issues.
With the fans in place, the Okeanos is nearly square, but ours is shifted a fair bit more to the left than most will see. We found, that there should be no issues with the first slot on the motherboard while aligning the cooler vertically, and with the fans blowing from the opposite side of the cooler, it is also free from obstruction.
If the cooler was vertically installed, it would not go so far to the right of the motherboard. For those wanting to use three fans, please note: this isn't as wide as the cooler would be, and just might cause some issues when trying to get to the eight-pin. For quad channel system users, make sure the heatspreaders are either low, or removable like ours are.
The Reeven Okeanos is one big cooler no matter its orientation, and will cause some issues all around with screws and memory. However, past submissions have shown us that as long as you are not swapping out memory and cases all the time, these coolers are worth the hassle to get them installed.
Test System Setup, Thermal Tests and Noise Results
Test System Setup
To see our testing methodology, and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.
With stock level load applied to the Okeanos, we find it resulted in an average of 50.25 degrees across multiple runs. Falling just slightly behind the Noctua NH-D15 and GamerStorm Assassin is a great showing for Reeven, and it does top the performance of the majority of air coolers on that list.
With the overclock applied, and many tests run, we found the average temperature to be 70 degrees flat. It closes the gap to the Noctua NH-D15, as it becomes the number two air cooling solution in our chart.
Noise Level Results
With the voltage limited, and the fans cruising at 1275 and 1100 RPMs (for the 120mm and 140mm fans respectively), we find the noise level to be plainly audible, but still tolerable at 38 dB.
Just for reference, these are also very close to the speeds that the adapters would provide, so this could also be as loud as the cooler would ever get with them installed.
The Okeanos suffers in the same department as the Ouranos, and that is here in the full speed fan testing. Where all the other coolers in this segment can do what they do with much less noise, Reeven throws silence to the wind, and allows the cooler to get to 62 dB while under full stress.
As for the fans, the 120mm fan reported speeds of 1900 RPMs, and the 140mm fan spun at 1650 RPMs with 12V running through them.
First, let us set everything on the square and level, so there are not any questions later on the topic. We did in fact have issues with the width of the heat pipes; more specifically, how far they spread across the cooler. This caused a conflict with the plastic armor above the socket, and we needed quite a bit more room to get the base anywhere near centered to attempt to mount vertically. Most users will not run into this issue unless you happen to have very tall heat sinks covering the power delivery system on your motherboard.
We also had the fans installed in our images just for show purposes; when it came to testing, we had the fans blowing at the video card, as not to introduce its heat into our sample during testing. Also, since we test in many orientations, initial installation is not so much of an issue, as we can revolve the chassis to get the fans and cooler oriented properly for the best functionality.
With that out of the way, we have very little negatives to discuss. The coolers fin stacks will indeed clear the memory slots, but with tall memory, even a 120mm fan on the front may come in conflict. If you planned to hang another 140mm on the back, let us persuade you to choose a 120mm instead to encounter fewer issues with memory on a quad channel motherboard.
On the flip side of that coin, there is a lot to like about the Okeanos. It does take up a fair bit of real estate, but it looks really nice with the sleek and stylish top plates on the towers. While it may take some time to get the cooler securely mounted, the performance we saw makes it all worth it. While it doesn't take over the top slot, being number two in air coolers is nothing to be ashamed of. Also, considering everyone else has had much more time in development to get where they are than Reeven has, the Okeanos proves that Reeven knows exactly what customers want, and is fully able to deliver it.
We really like that even while using two sizes of fans to offer some clearance where it is needed, there isn't a drastic offset in their performance. With everything being very close in CFM, pressure, and noise, the only thing that really changes is that the 120mm fan has to spin a few hundred RPM faster to keep up with the 140mm fan.
We also noticed that most of the other dual-tower designs were able to offer their results while keeping sound levels to a much more acceptable limit. However, we all know that when you find a great deal, there is usually a reason why it is such a great deal. Not that it is a crutch in our opinion, but if you want silence, it will cost you a bit more to get that.
While we really do wish that these coolers were already on the shelves, and ready to be plucked when everyone sees this review and the desire is strongest, we are still waiting with no real anticipated date of arrival. However, in all honestly, the Okeanos may very well be worth the wait. The NH-D15 is still the reigning champ, but for $20 in savings, if silence is not mandatory, Reeven has a boldly colored, very attractive dual-tower CPU cooler in their Okeanos. In our opinion, the Okeanos is a great deal to be had, and once they arrive somewhere, we can, and probably will buy them.

|Value for Money||96%|
The Bottom Line: Reeven tried its hand at dual-tower air cooling and wins silver! With only the legendary D15 in front of it, the Okeanos saves you a fair bit of an investment for very similar results - just keep in mind this is not a silent as all the others.
