Reeven Okeanos RC-1402 CPU Cooler Review

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.
