Reeven Okeanos CPU Cooler Review 0 199

A New Tower on the Block – The PerformancePSU Review

Reeven is a new emerging hardware start-up with a small but targeted range of products aimed at pc overclocking enthusiasts, from 77.8CFM case fans to Fan controllers and CPU tower air coolers, Reeven are certainly trying to make a bold statement with their slick debut product line.

When Jerry contacted me and ask if I would be interested in reviewing their products I was all to happy to oblige, after all it’s hard for smaller companies to get noticed – A little more competition won’t do any harm.


I am going to be reviewing the Reeven Okeanos universal CPU air cooler. Constructed with aluminum fins, 6 nickel-plated copper heat-pipes and coming supplied with 1 x 120mm fan and 1 x 140mm fan, Reeven are definitely not messing around when it comes to their dual-tower flagship CPU cooler.

Let’s take a look at what’s inside the box and how easy CPU cooler is to install.

Unboxing & Installation

When I opened the box and saw how quite frankly huge it was, I started to get a little bit excited – It really looks like it has some real cooling potential, its dual aluminum tower design with 6 copper heat pipes really screams ‘overclock me’.

Reeven have gone through a great deal of effort to brand themselves and their Okeanos CPU cooler packaging with very distinctive black and yellow letters and icons.

Just like the care that has gone into the box, its clear to see the effort they have put into their flagship tower cpu cooler with its very slick design and subtle branding.

While the polish is not the greatest I have seen Reeven’s Okeanos is at least not the worst either providing a solid finish with a few minor machine swirls.

Reeven Okeanos Installation

Installation was not as smooth as I would have liked but that’s to be expected with such a huge piece of cooling kit. Thankfully I did not face any clearance issues when installing the Okeanos tower in our Fractal Design Arc XL, with a little perseverance I managed to get this huge cooler installed.

My only real complaint trying to install this CPU cooler was when it come to the fans. The Okeanos only just about had enough clearance as it is, trying to get those clips to secure in such a tight space was not a straight forward task. Despite this small detail it was still reasonably easy to install and looks fantastic when is installed.

Test Bed & Testing Methodology

We are going to be using our trusted Intel Skylake test bed which has proven to give a wide variety of hardware a considerable workout.

  • CPU: Intel 6700K (Skylake)
  • Motherboard: Gigabyte Z170x Gaming 7 Motherboard
  • Memory: G.SKILL Ripjaws 4 DDR4-3333mhz @ 16-18-18-38-1T
  • GPU: EVGA 980Ti 6GB Superclocked ACX2.0+
  • HDD: 500GB Samsung EVO 650 M.2
  • Power Supply: Seasonic P-Series 1000W Fully Modular

How we tested?

Idle Temperatures were taken after 15 minutes of OCCT followed by a 15 minute idle period after which temperatures were then taken. I manually overclocked the CPU without the use of presets so I could really dial in what this awesome cpu cooler is potentially capable of.

All overclocks we’re stability tested for 1 hour.

Stability Tools Use

  • Intel XTU Stress Test
  • PCMark
  • OCCT CPU Stress Test
  • SuperPI 32B

Reeven Okeanos Performance Testing

First up in our Reeven Okeanos performance tests is to see how this unit performs with everything set to default in the bios. During our stock tests, the room temperature was 24.7*c with idle temperatures sitting nicely at 26*c, that’s just 1.3*c above ambient!

During processor stress test’s this CPU cooler managed a maximum load temperature of just 55*c, that’s pretty good going for an air and should allow us plenty of overclocking room later.

Mild Overclock – 4400Mhz / Stock VID

Due to Intel’s Speedstep technology, Idle temperatures were no different despite the higher cpu ratio however, when it come to testing stability temperatures soon hiked over stock with a highest temperature of 63*c, that’s +8*c just from increasing the ratio.

Respectable Overclock: 4700Mhz / + 0.25Mv

During this test the ambient room temperature dropped to 24.3*C with idle temperatures staying the same despite a 0.25v increase in voltage.

Tests completed without a hitch with temperatures rising to a maximum of 69*c, that’s a reasonable 24/7 safe overclock right there.

Turning up the heat: 4800Mhz / + 0.50Mv

With almost every test failing the moment I pressed the start button, it’s fair to say that the Okeanos was not up to the task but, asking it to deal with high voltage and the added heat was a big ask, that put a side it done a great job.

Conclusion

Where should I start with this one? Reeven have tried really hard to appeal to overclockers with this cooler. It’s a solid piece of kit for those not wanting to get flashy with liquid pc cooling. The provided fans provide both ample airflow while keeping things near silent as well, this really is a great piece of kit.

You wont be hitting mind-blowing overclocks but you will be able to attain a respectable 24/7 overclock and keep things safe. Let’s face it, who doesn’t want more speed?“.

As mentioned in the installation instructions, the only thing that lets down this quite frankly amazing CPU tower cooler is the installation of the unit. You could try attaching the fans first but then you will just have to remove one to then secure it in place. This aside, if you have an extra 10 minutes to install the Okeanos CPU Tower then supporting the small guys would be a wise choice.

I give Reeven a strong 4.8 / 5 and a pat on the back for such an exceptional debut product.

I would like to thank Reeven for providing this sample to review. We ensure all our reviews are impartial and honest.
