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.

http://www.anandtech.com/show/6830/cpu-air-cooler-...It is far more impressive than you give it credit for. I easily hit >5ghz on this fan with i4790K.

If you're going to extreme OCing, why the hell aren't you on custom water cooling or Dice/LN2?Nfarce - Wednesday, July 8, 2015 - link
Because where I am in overclock, the best air keeps up with the best closed loop kit cooling for far less money.tabascosauz - Monday, July 6, 2015 - link
What farce said is true. At high voltages and overclocks, the 212 EVO breaks down and the dual towers begin to shine.DanNeely - Monday, July 6, 2015 - link
Which with simulated thermal loads ranging from 60-340W should have been made apparent in the course of testing.I would hope and expect that most if not all of these coolers would out perform it, especially at higher loads. But as a de-facto standard budget cooler for people who want something better than Intel's I think it should've been added to the matrix to show how much better these bigger ones performed. A stock Intel cooler should've been included as well for the same purposes (at least at the lower loads; no sense risking burning the test setup by trying to broil 340W through it). Including a mainstream reference point is especially important in this case because E. Fylladitakis's synthetic test load means that we can't cross reference his results with those found elsewhere.

Totally agree - to get the full picture and to aid comparability with other tests the reference points of the Intel stock cooler (free) and CM 212 EVO (£25) should be included.Flunk - Monday, July 6, 2015 - link
If you buy one of those things on sale I've seen them as low as $30, which if you don't need better cooling, is a good deal. The reason the Hyper 212 EVO is popular is that it's cheaper than most of it's competition and easily available. They're good enough for moderate overclocking on a 1150-series chip so they do fit the bill for a lot of people. Something being popular doesn't make it bad.Pastuch - Monday, July 6, 2015 - link
I have 2 of the original Hyper 212 (Non-evo) on two different I5-2500Ks that have been running super quiet at 4.4ghz for the last 4+ years. No coil whine or bearing degradation on the fans. I paid $20 for each Hyper 212 Evo. The value for the money is amazing. It's an excellent quality reliable product and it's easy to install.I paid $220 for my I5-2500k, 20$ for the Hyper 212 Evo, and $70 for 8gbs of PC 1333 in February of 2011. At 4.4ghz, it's still within 5% as fast as any CPU on the market. Sandy Bridge FOREVER! I'll keep buying video cards. You can waste your money on HSF upgrades for CPUs that become less important every day. DX12 is just going to make the CPU even less useful.

Just to clarify, those are Canadian prices which makes them even more amazing. The new I5-K in Canada is almost $300! No thanks.northward - Monday, July 6, 2015 - link
Remember, the average exchange in 2011 was 1.011 (CAD to USD). It is presently 0.79 (CAD to USD). Assuming US/CAN price parity in 2011, that $220 cooler would cost ~$278, not that far behind the $284 i5 4690K.
