fanconverters

Fanconverters are devices designed to interface between different types of fan connectors, primarily found in computer hardware. They are typically used to adapt a fan's existing connector to a different standard, such as converting a 3-pin fan connector to a 4-pin PWM (Pulse Width Modulation) header or vice-versa. This allows users to install fans with incompatible connectors into motherboards or fan controllers that only support a specific type.

The functionality of a fanconverter can vary. Some simply act as passive adapters, changing the physical plug while maintaining the electrical signals. Others may include active components, like resistors or basic circuitry, to regulate fan speed or voltage. For instance, a 3-pin to 4-pin converter might convert a voltage-controlled fan signal to a PWM signal, or a 4-pin to 3-pin converter might reduce a PWM signal to a simpler voltage control.

These converters are often small and unobtrusive, making them easy to install within a computer case. They are particularly useful for users who want to upgrade or replace existing case fans with models that have different connector types than what their motherboard or controller provides. While generally reliable, it's important to ensure compatibility between the fan, the converter, and the header it connects to, to avoid potential performance issues or damage.
