Forced air and passive-cooling are actually pretty commonly used together (for example fans and heat sinks on CPUs) so is it is not OR situation...It's also very strange to have both fans and a big passive radiator. It's neither forced-air cooled nor passive-cooled. It must be quite expensive to manufacture all that heatsink for nothing.
Forced air devices have the advantage of be able to operate in warmer areas, passive ones can not.
But in this particular case 2 fans are used mostly for pulling air from PSUs to cool those 2 down and also improve SFPs cooling, switch chip is cooled by the large heatsink with pipes, actually there is an empty space and connector for additional fan that you can connect and use to improve air flow along heat sink if switch is used in wormer areas although that would probably void the warranty...
