Reeven Okeanos RC-1402 Review


Reeven Okeanos RC-1402 Closer Look:

The RC-1402 is a dual tower cooler with a two fans. Both fans are PWM units with the front fan being 120mm and the center fan is 140mm. The Okeanos comes with three sets of fan clips, so you can add a third fan, if you choose. There are 57 aluminum fins in each stack. Topping off the fin stacks are decorative top cover plates featuring the REEVEN logo stamped neatly through the center. The top plates also cover the termination points of the heat pipes and are secured with four flat head rivet-style fasteners. Some manufacturers leave the termination stubs visible, but Reeven keeps them covered up, and that makes for an aesthetically pleasing cooler, which looks good from any angle. At 163mm high, this cooler should fit most larger cases, but it is always a good idea to make sure you have the room in your case.




From the top, the Reeven logo on the decorative top plate catches your attention. The Reeven logo is also on the 140mm fan frame, but not on the 120mm fan frame. From the side view you can see how the towers are symmetric relative to the base center line. 


The Reeven logo is stamped in the top plates in an opposing manner so the logo can be easily read regardless of the orientation. The size (surface area), thickness, and density of the fins play a major role in the ability of a cooler to effectively remove heat. Another significant factor is the placement of the heat pipes within the stack, which we will see shortly. All of these things come together along with good air flow to deliver a cooler that will keep your CPU from cooking when the heat is turned up. The symmetry between the towers is more evident when the fans are removed.



Looking from the side, we see that the towers are, again, clearly symmetrical and the base is not offset like it is on the Ouranos. The layout of the six nickel plated heat pipes also diverges from the Ouranos design. The two larger 8mm heat pipes that emanate from the center of the base run up through the center of the fin stack, while on the Ouranos, they are towards the outer portions of the fin stack. There are four 6mm heat pipes (two on either side of the 8mm heat pipes) that bend toward the sides of the stack. They all travel vertically up through the fin stack and they are spaced to maximize the exposure to the air flow. Of course, at this point, I have not done any testing, so it will be interesting to see how this heat pipe arrangement performs. The top of the base is an aluminum extrusion with two raised guides on either side of a central groove. The groove and guides will locate the mounting bar that will secure the cooler to the  mounting bracket, which we will see later.



The base plate is machined flat and nickel plated. All of the nickel plated heat pipes are soldered between the two-piece base. Don't forget to peel off the plastic cover before you apply your thermal paste. If you gave the fans a test fit, you will have to remove them during the installation in order to access the installation screws. Here I have the protective cover peeled off and the base is ready for the application of the thermal paste.


Time to go over the fans. Another contributing factor to cooler capacity is of course, air flow. To move a lot of air, you need a large fan (or fans) and the bright yellow 9 blade 140mm PWM fan can do just that. It is rated at 0.25 amps, and can move up to 92.4 CFM of air. The rated speed is 300 to 1700 RPM with a noise level of 5.8 ~ 36.4dBA. The smaller 120mm eleven blade fan is no slouch, as it can move 92.5 CFM at 1800 RPM. So clearly we have a couple of fans that are capable of moving air through the two towers. The power cables are nicely sheathed in braided, black plastic covers. This is becoming a common practice now across many manufacturers and really helps to keep your cable routing clean.



As for the installation, Reeven uses the same multi-piece method on both the Ouranos and the Okeanos. The method is effective, but a little cumbersome. I think it could be simplified to integrate the mounting screws into the cooler base, similar to the way that Noctua and others have been using for years. Regardless, the rear mounting uses a typical metal back plate. Tower style coolers usually need the additional support of a firm back plate. There are four studs that push through the motherboard and screw into the mounting bracket that will install from the front.



Here is the mounting bracket. It sits on top of four plastic spacers and four nuts holding the mounting bracket to the four studs that are attached to the rear back plate. The the cooler is secured to the mounting bracket with a mounting bar and two screws. The mounting bracket can be rotated 90° to change the orientation of the cooler.

The first RAM slot is very close to the edge of the cooler - now you know why Reeve supplies a 120mm fan for this end of the cooler - a 140mm fan would be too large on this end and cause RAM interference. Low profile RAM should not have any problems, but if your RAM has tall heat spreaders, I suggest a test fit. All you have to do now is attach the fans and plug them into the CPU fan headers and power it up.


With the fans installed, you can see that it is tight for the first two RAM slots, and if you have RAM with tall heat spreaders, you can move the fan up a little. The Okeanos is large, but not too large. It looks nice in my test system. Ok, everything looks good, so let's see what happens when we turn up the heat.
