Top Tier CPU Air Coolers Q3 2015: 9-Way Roundup Review
by E. Fylladitakis on July 6, 2015 8:00 AM ESTThe Reeven Okeanos RC-1402
Reeven is a Taiwanese newcomer in the industry. Naturally, most people reading this probably never even heard the company name before today. The company was founded just over a year ago and currently only offers CPU coolers, fans and fan controllers. Reeven sent us their most powerful CPU cooler as well, the Okeanos (RC-1402).
The box that the Reeven comes supplied in is relatively small. Nevertheless, the protection appears adequate, with polyethylene foam protecting the cooler and the bundled items packed inside a cardboard box.
The bundle is a little crudely packed and virtually kept to a minimum. Reeven supplies only the hardware necessary for the mounting of the cooler, a single dose of thermal grease, wire clips for up to three cooling fans, speed reducers for the two provided fans and a leaflet with basic installation instructions.
Reeven supplies two cooling fans alongside with the Okeanos, one 120 mm and one 140 mm fan. Both fans have black frames and genista yellow blades. These are relatively simple models, with sleeve bearings, lacking fancy blades or vibration absorbers. There is one thing of note about these two fans though: they are ridiculously powerful, with the 140 mm and the 120 mm fan rated for a maximum speed of 1700 RPM and 1800 RPM respectively.
The Okeanos is a symmetric dual tower CPU cooler, with strangely narrow towers for its class. Although the difference is very small, the fins of each tower are not precisely geometrically symmetric, with the front side having three small and the rear side one long indentations. The top fin is a 1 mm thick aluminum cover with the company logo punched on it.
The wire fan installation clips do allow moving the front fan upwards in order to gain some RAM clearance - as long as the case is wide enough, of course. Installation-wise, they are a bit of a pain, as Reeven's approach is far too crude, with the wire clips just going straight into the fan holes and clipping onto the side of the fan.
Furthermore, the frame of the 120 mm fan just barely touches the extruded sides of the fins. It is very easy for the 120 mm fan to be installed with only one side on the extruded fins, increasing noise and reducing performance.
Even though the Okeanos initially looks very simple, the bottom of the cooler makes it very interesting. The base is split between a nickel-plated copper lower part and a steel top part, providing mechanical cohesion and retention. In between these two parts, there are six heatpipes, secured with a very generous amount of solder. The two central heatpipes are 8 mm thick, while the other four heatpipes are 6 mm thick, making this the only cooler with an asymmetric heatpipe configuration in our review. The contact surface is well polished and free of imperfections, yet not machined down to a perfect mirror finish.

Used to have 212+ once. Later I swapped out for a cheap closed-loop. Though the CPU temp is a few C lower, the closed-loop was much louder than the 212+ (due the the 'pump whine').Years later I upgrade the rig to a Core i5, which is not really that hot, and I'm not interested in overclocking anymore (being more mature I guess).
I find the 212 is pretty good for its price. It's a great entry-level cooler for those who want to upgrade. I also think that it could serve well as a baseline for the comparision.

I didn't know that overclocking enthusiast would prefer a lower performing heatsink instead of the best available. The reason is simple; CPUs consume less power throughout the years even with continuous but non synthetic workloads including gaming.Many years ago, I was a fan of watercooling then big-air heatsinks then not anymore. It is just not logical anymore as they are more expensive, larger, and cumbersome.

To me, the whole point of overclocking is to get a better cpu than what you paid for. So overpaying for a heat sink doesn't make sense - the whole point is to get the best possible performance, while spending the least amount of money. At least that is what overclocking means to me, and I'm sure a lot of other people as well.Ian Cutress - Monday, July 6, 2015 - link
That's usually how most people start with overclocking. For others, it's getting the best performance regardless. That's why people still that the i7-K and push it, rather than a Pentium-K and tweak it.kmmatney - Monday, July 6, 2015 - link
I bought my Hyper 212 for $19.99 - a much bigger savings than $10. It does the job, and in the end my overclock was not limited by temperature, but by the CPU itself. A more expensive heatsink wouldn't gain me anything.aj654987 - Wednesday, July 8, 2015 - link
What are you even talking about. The 212 is $35 and half the cost of many of these heatsinks. Its been the gold standard for years, if you only get another 1 C out of a HSF that cost double then its not worth it.CummingsSM - Thursday, July 9, 2015 - link
Yep. You save $9.99 and then this happens: https://i.imgur.com/COC5qW9.jpg(In case someone is wondering: No, I didn't over-torque it, the bolt got caught in the back-plate and sheared under the power of a screwdriver lightly applied; And yes, that bolt is hollow; And yes, that is the mounting hardware from a CM 212 EVO; And yes, I'm done buying CM products.)

Are you kidding me? Intel's CPUs might be efficient compared to AMD's, but there is hardly a valid reason to dismiss the dual-tower crowd. Intel's CPUs are hotter than they have been in years, thermal performance having declined steadily since Sandy Bridge due to sh*ttier and sh*ttier TIM and other reasons.rickon66 - Monday, July 6, 2015 - link
Regarding the CM 212+/EVO -They did not want to show a $25 cooler that beat the expensive guys.
