Reeven Ouranos RC-1401 Review


Reeven Ouranos RC-1401 Closer Look:

The RC-1401 is a single tower cooler with a large 140mm PWM fan. There are 55 aluminum fins capped off with a decorative top cover plate featuring the REEVEN logo stamped neatly through the center. The top plate also covers the termination points of the heat pipes and is 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 161mm 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 logo is even on the fan frame. From the side view, you can see how the base is offset from the center line of the fin stack, and this of course is for RAM clearance.



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 symmetrical fin stack is nicely made and feels like a larger cooler than it is.



And here is what makes the Ouranos potent - we have six nickel plated heat pipes, but Reeven goes about things a little differently. There are two monster 8mm heat pipes in the center, flanked on either side by two 6mm heat pipes. They travel vertically up through the fin stack and they are spaced to maximize the exposure to the air flow. You can see the 8mm heat pipes are towards the outer edge of the fin stack, where the most air flow is. And the heavy offset of the base, which comes in handy for RAM clearance, is more obvious from this angle. 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 fan a test fit, you will have to remove it during the installation in order to access the installation screws.


Let's talk about the fan. Another contributing factor to cooler capacity is, of course, air flow. To move a lot of air, you need a large fan, 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 power cable is nicely sheathed in a braided, black plastic cover. This is becoming a common practice now across manufacturers and really helps to keep your cable routing clean and tidy.



As for the installation, Reeven uses a multi-piece method that 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 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 hold 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. RAM clearance is facilitated by the offset of the base. This allows full access to the RAM slots. All you have to do now is attach the fan and plug it into one of the CPU fan headers and power it up. RAM in the first slot is accessible before the fan is installed.


With the fan installed, you can see that it is tight for the first RAM slot, and if you have RAM with tall heat spreaders, you can move the fan up a little. Ok, everything looks good, so let's see what happens when we turn up the heat.
