Specifications to keep in mind
These are specifications to keep in mind when purchasing fans for your computer:
- Fan size; you want to make sure that the fans you are purchasing are the right size for your tower
- Number of pins; the number of connector that the fan has when connecting to the rest of the system affects how it functions;
3-pin fans run at max RPM at all times; 4-pin fans have a variable RPM that is controlled by the motherboard.
