Q: How many fans should a gaming computer have?

A: It is always our recommendation that you buy cases with a minimum of 3 fans (or at least slots for adding them yourself) for gaming systems, not counting the power supply, CPU, and GPU fans. I know we say this about a lot of things (especially power supplies), but you really don’t want to skimp on cooling.

Q: What is the CFM of a PC fan?

A: Short for cubic feet per minute, CFM sometimes abbreviated as CFPM is the air flow measurement used when describing how much air a fan or computer case fan is capable of distributing. The higher the CFM the more air the fan is capable of distributing, 70 CFM or more is a good starting value.
