Different Types Of Computer Fans

Centrifugal fans with forwarded blades are suited for application with higher air flow volumes and pressures.

Different types of computer fans.

Best known as the basic functional devices used for cooling purposes and dissipating heat the use and existence of fans date all the way back to 3000 b c. There are a lot of terms used to describe different types computers. This how to guide explains the nitty gritty of getting the right fan and mounting it to your pc s cpu.

Not only do different fan sizes populate the market a byzantine maze of cpu socket types bearing technologies fan speeds and more greatly complicate the selection process. Axial propeller fans are more suited for applications with lower volumes and pressures.
