Cooling the MOSFETs
We already know that the biggest weakness of the cooler are fans. So, we replaced them with reference models and observed the difference. This led to a remarkable comparison of Okeanos and Noctua NH-D15 heatsinks. And there are few surprises even in modes without the same fans. Let’s take a look at how Okreanos manages to cool the area around the socket, and what it really can do in passive mode.
Cooling the MOSFETs
Cooler | Speed and voltage of the fan | ||||
39 dBA | 33 dBA | ||||
Arctic Freezer 33 | 1× 1148 rpm | 8.8 V | 1× 848 rpm | 6.23 V | |
SilentiumPC Fera 3 v2 | 1× 1393 rpm | 9.4 V | 1× 971 rpm | 6.59 V | |
Noctua NH-D15 | 2× 1073 rpm | 8.1 V | 2× 700 rpm | 5.87 V | |
Reeven Okeanos | 2× (1044 + ? rpm) | 7.77 V | 2× (800 + ? rpm) | 7.58 V |
