FAQ:

Q: What is the CFM of a computer 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.

Q: What are the dimensions of a 120mm fan?

A: What are the dimensions of a 120mm fan. Fan Dimensions: 120mm x 120mm x 25mm.

Q: What is a CPU fan?

A: A Central Processing Unit (CPU) is the main microchip in a computer, while a CPU fan is the dedicated fan that helps keep the processor cool. Processors generate heat from internal electrical energy. The more demand placed on a CPU, the harder it works, and the warmer it gets.
