Seasonic S12 Energy Plus Power Supply

As we can see, the aluminum heatsink has fins that are staggered and bent in
a T-shape. This allows maximum cooling for not only the heatsink but for all
the components underneath as well. We can see the Adda 120mm cooling fan in
charge of keeping this cool and quiet. When powered up on the bench the fan
was quiet and still managed to move a decent amount of air.
