Default Speed Passion Reventon Pro fan or no fan?

Just setting up my cougar SV2 after not racing for 15 years, things have changed! Everything seems a tight fit and I wanted to know how critical it is using the fan with the esc? I notice some ecs's don't have fans. I'm using a speed passion reventon pro. Thoughts please......
