Question Are the two fans that come with the Corsair 4000D Airflow good enough?

I heard that you should add more if you choose to overclock? For the moment I don't intend to do that so is the two that come with it good enough?

Depends on your system specs, but the case comes with a rear exhaust fan which is the most important one and makes the biggest difference as to having no fans at all, since its pulling all the hot air out of the system. If your pc runs without overheating with a that single exhaust fan than you have enough fans. But if you could, get 2 more 120mm fans to add onto that 1 which also comes with the case and put them in the front so you can have fresh air going into your system, because intake is also important. Ultimately you want 1 rear exhaust fan and 2 top exhaust fans, getting all the hot air out, and 3 front intake fans, bringing the fresh cold air into your system.
