Three years have past since we last tested a heatsink from Reeven, an upstart that is still unfamiliar to most DIYers. The Kelveros, Arcziel, and Vanxie coolers were budget models but still underwhelming and forgettable in most regards except for their yellow fans. Their latest offering to our test bench is a more concerted effort, their take on the premium dual tower/fan heatsink. Such flagships from respected manufacturers start for around US$80 and are available worldwide. The Okeanos is selling for the equivalent of US$60~$70, though it can only be found in limited locations (Australia and parts of Europe).


The box.


Package contents.

The Okeanos ships in a compact but colorful bespecked box. Inside, you’ll find the cooler sandwiched between two PWM fans (one 140 mm in size, the other 120 mm), and an accessory box hardware separating the two towers and keeping them in place. The mounting system is typical for this day and age and includes a universal backplate and mounting frame compatible with all Intel/AMD desktop sockets released in the last decade except for LGA775. Three sets of fan clips are provided, as are adapters to lower the top speed of the fans, a wrench, and a small packet of thermal grease. One notable omission is a Y-cable for running both fans off the same fan header. As for the heatsink itself, it’s shaped in a similar fashion to most flagship models though each stack of fins is noticeably thin, which may explain the lower price-tag.

PHYSICAL DETAILS

The Reeven Okeanos is composed of 57 aluminum fins friction-fit
to 4 x 6 mm and 2 x 8 mm thick nickel-plated copper heatpipes, which in turn, are soldered to a nickel-plated
copper base. According to my measurements, the heatsink’s dimensions are 14.0 x 10.8 x 16.4 cm (W x D x H) and it weighs 790 grams (about 20% less than similar models). The stock fans add an additional 160 grams each to that total, but they do not increase the overall height.


In profile.


The two heatpipes in the center measure 8 mm across, while the four on the sides are of the more conventional 6 mm diameter variety. The 0.31 mm thick fins are packed in tightly, with each layer spaced approximately 1.90 mm apart from one another.


On average, each tower is just 34 mm thick, and separated by a 33 mm gap. The name plate has a slick eye-catching design with a pleasing brush metal finish. The three columns of holes stamped on each side of the company logo make the heatsink appear more ventilated than in actuality.


The contours of the heatsink face ensure that some separation is provided whether 140 or 120 mm fans are used.


The base has a lustrous shine but the finish is some ways off from being truly reflective. The surface is covered in fine machine marks surrounding the pinprick-like apex. The surface is convex, shaped in a similar fashion to the latest crop of Scythe heatsinks.


The included fans are not remarkable in appearance aside from their bright yellow coloring. The blades are gently swept forward in an almost peaceful manner.

INSTALLATION

The most critical aspect of installation is firm, maximum contact
between the base and the CPU heatspreader for efficient heat conduction. Ideally
it should also be a simple procedure with the user having to handle as few pieces
of hardware as possible.

For the Okeanos, Reeven has adopted a similar system used by current industry leaders. It involves putting together a metal mounting rig around the CPU socket and pinning the heatsink to it using a thick crossbeam over the base of the heatsink to apply downward pressure in order to ensure good contact.


For Intel installs, bolts are inserted through the appropriate mounting holes and held fast with the help of stiff rubber washers. Plastic columns are used to ensure proper spacing for the mounting frame which is secured to the bolts using nuts. The crossbar hooks over the heatsink base and is screwed into the frame.


Fully installed.


I’m not a proponent of using disparate fans on a heatsink but having a smaller 120 mm variant on the outside does help memory compatibility somewhat as it falls no lower than the last fin, which resides 44 mm above the motherboard PCB.


On our LGA1366 test board, the fan hangs over two closest DIMM slots and part of the third.


The resulting thermal compound imprint is indicative of a convex base with severe branching along the outside and fainter patterns along the inside. Contact at the center, where it matters most, appears to be excellent.

Measurement and Analysis Tools

  • Extech 380803 AC power analyzer / data logger for measuring AC system
    power.
  • Custom-built, four-channel variable DC power supply, used to regulate
    the fan speed during the test.
  • PC-based spectrum analyzer:
    SpectraPlus with ACO Pacific mic and M-Audio digital
    audio interfaces.
  • Anechoic chamber
    with ambient level of 11 dBA or lower
  • Various other tools for testing fans, as documented in our
    standard fan testing methodology
    .
  • SpeedFan,
    used to monitor the on-chip thermal sensors. The sensors are not calibrated,
    so results are not universally applicable. The hottest core reading is used.
  • Prime95,
    used to stress the CPU heavily, generating more heat than most real applications.
    All instances are used to ensure full stress.
  • CPU-Z,used to monitor the CPU speed to determine when overheating occurs.
  • Thermometers to measure the air temperature around the test platform
    and near the intake of the heatsink fan.

Noise measurements are made with the fans powered from a separate, fanless system. Load testing was accomplished using Prime95 to stress the processor, and the
graph function in SpeedFan was used to ensure that the load temperature is stable
for at least ten minutes. The temperature recorded is the highest single core
reading. The stock fans were tested at various voltages to represent a good
cross-section of airflow and noise performance.

The ambient conditions during testing were 10~11 dBA and 21~23°C.

The larger fan positioned at the center of the heatsink utilizes a a frame that makes no effort to conform to a conventional rounded or hexagonal shape, with corners protruding like a staircase. Despite this, it has the same overall dimensions as standard 140 mm case fan and 120 mm mounting holes for improved compatibility. Its nine broad blades are slightly curved and the corners of the leading edges have been squared off in similar fashion to Scythe’s GlideStream line. The straight struts form an acute angle with the blades which often increases tonality. The fan has an unusually high starting voltage but its rated 300 RPM minimum speed on PWM control is also attainable on DC control.

The 120 mm stock fan is housed in a traditional box frame. Its 11 blades are lankier but are otherwise of similar design though the struts are advantageously curved in the opposite direction. The size of the hub is the same as the larger fan, looking out of place on the smaller model, and perhaps taking away some of its airflow potential. Like its big brother, it can hit 300 RPM without issue using both PWM and DC control.

Though the two fans are high speed models, they are capable of reaching very low speeds as well, making them suitable whether the user’s bias is toward performance or silence. On PWM control, at 30% speed, the noise generated is practically inaudible in our anechoic chamber, so there’s no need to go any lower. For our noise standards, the speed of both fans should be limited to 900 RPM or lower to maintain a quiet system. At about 50% speed and above, the smaller fan becomes noticeably faster and louder than the larger. The combined noise level begins to become intolerable at only 60% speed.

Aside from a very faint clicking audible at close proximity, the 140 mm stock fan has a gentle sound, though it does start to get whiny and turbulent at higher speeds. The 120 mm model is not quite as graceful, putting out more bearing chatter, but its overall disposition is still agreeable. On their own, the included fans produce pleasant acoustics but together on the same heatsink, intermodulation rears its ugly head. Beginning at about 45% speed, a noticeable hum takes shape at close to 160 Hz. At 60% speed, an annoying buzzing starts to form at ~400 Hz.

The Okeanos performs admirably on our test platform, keeping the thermal rise at 40°C or lower at every tested fan speed in dual fan configuration. Its cooling capability varies little as the fan speed drops, with a difference of 8°C separating 100% and 30% speed on PWM control. Given its dual tower design, performance with just the fan at the center is significantly worse. The stock fan setup outpaces our reference fans slightly at every comparable level.

Amongst coolers equipped with twin fans, the Okeanos lands in the top four, wedged comfortably in position between the Thermalright Silver Arrow and Noctua NH-C14.

MP3 SOUND RECORDINGS

These recordings were made with a high
resolution, lab quality, digital recording system
inside SPCR’s
own 11 dBA ambient anechoic chamber
, then converted to LAME 128kbps
encoded MP3s. We’ve listened long and hard to ensure there is no audible degradation
from the original WAV files to these MP3s. They represent a quick snapshot of
what we heard during the review.

These recordings are intended to give you an idea of how the product sounds
in actual use — one meter is a reasonable typical distance between a computer
or computer component and your ear. The recording contains stretches of ambient
noise that you can use to judge the relative loudness of the subject. Be aware
that very quiet subjects may not be audible — if we couldn’t hear it from
one meter, chances are we couldn’t record it either!

The recording starts with 5 second segments of room ambiance, then the fan
at various levels. For the most realistic results, set the volume so that
the starting ambient level is just barely audible, then don’t change the volume
setting again.

FINAL THOUGHTS

The Reeven Okeanos is one of the most effective dual fan heatsinks on the market despite having a leaner construction than similar models in its class. Its aluminum fins are not overly thick from nickel-plating and as a result, they managed to pack in 57 fins, creating twin arrays with an ample amount of surface area for heat dissipation. Like similar systems, their mounting scheme generates good contact between the convex base and the CPU heatspreader and is easily assembled though I wish the nuts used to setup the mounting frame could be tightened with screws rather than a wrench or pliers. The included fans have a far superior sound when used individually but intermodulation effects are not noticeable at lower fan speeds. If appearances are important, the name plate gracing the top of the towers is perhaps the most stylish I’ve encountered, though yellow fans may not be everyone’s cup of tea.

This is a complete turnaround compared to the first Reeven products we reviewed three years ago. The Kelveros, Arcziel, and Vanxie were budget coolers but even so, they were unremarkable while the Okeanos is far more memorable. It manages to not only compete with, but also undercut some of the biggest baddest air coolers from the most respected of manufacturers. Its biggest issue is its limited regional availability though if you are in the right location, it can be purchased for the equivalent of US$60~$70, considerably less than most top-tier coolers of similar design. As good as a value as this appears to be, keep in mind it is still overpayment compared the best single fan heatsinks which can get you 95% of the way there for even less.

Our thanks to Reeven
for the Okeanos CPU cooler sample.
