Performance
The Okeanos offers reasonable performance at stock clocks. Nothing amazing, but certainly enough to be within a safe margin. I must admit though, I was expecting a lot more and many smaller coolers outperform it, such as the ID-Cooling 204K and the Cryorig H5 and H7.
Acoustic levels aren’t too bad, in fact, they’re pretty average. Not too loud to be a problem, but not exactly silent either.
The Okeanos didn’t handle our overclocked CPU very well. Sure the numbers are good enough to keep the system running, but for a dual tower, twin fan design, I have to admit that I was expecting more, especially given that the fans kicked up a bit of a fuss here. What’s worrying is I was also seeing temperature spikes every minutes or so, where the temperature would spike +5c and the fan speeds weren’t consistent.
The issues with the fan aren’t really recorded here, again the results are quite average, but while there wasn’t a big increase in dBa, there was a noticeable change in the pitch of the sound from the fans and more audible air turbulence.
Well, Okeanos is a strange name for an air cooler considering that okeanos is the Greek word (written in Latin characters) for ocean, and ocean is full of water. They should have kept the name for a water cooler.
Thanks for doing the review, but I simply don’t trust these results. Something must have been wrong with the installation or methodology. For example, there is no way the Reeven Justice 120mm single tower outcooled the Reeven Okeanos dual tower 120/140mm if both were mounted correctly and test conditions were adequately controlled. According to the Linus Tech Tips CPU Cooler Performance Tier List, the Okeanos is in the same tier as a Noctua D15.Other reviewers have confirmed this. I realize this review is 5years old, but the cooler is now in stock and just under the $60 price point. lolz
