Fans on in pc case

[matrixman]

I was told you need equal input and output on cpu fans. I was looking at getting a case that had 4 pre installed fans 3 in the front and 1 in the back and a family member told me "you need to do it right and get 2 more fans or it won't work right". 

 

Do I need to or not. It's only cooling a 5600 and a 6700xt right now.

 

I plan on upgrading in the future

It's not a hard requirement, but balanced in and out is prefered by most. Not having it balanced WILL NOT cause any damage though.

Current case?

If it suffocates your pc (solid front case) just take the sidepanel off and now your temperature problems are gone, no need to change out the case

Not needed.

Cases aren't sealed and any excess airflow will find its way through openings.

Intake and exhaust fans can also be more or less effective depending on the airflow grill / obstruction.

It's a scenario no current issue.

A lot of people prefer positive pressure - limits dust if the intakes have a filter:
