For example, you can set the limit at 25°C and if the temperature goes over that the click will
activate the fan; it will keep working until the temperature is 25°C again.
MAX31760controllerfeatures
The MAX31760 integrates temperature sensing along with precision PWM fan control. It
accurately measures its local die temperature and the remote temperature of a discrete diode-
connected transistor, such as a 2N3906, or a thermal diode commonly found on CPUs, graphics
processor units (GPUs), and other ASICs. Multiple temperature thresholds, such as local
high/overtemperature (OT) and remote high/overtemperature, can be set by an I

C-compatible
interface.
Fan speed is controlled based on the temperature reading as an index to a 48-byte lookup table
(LUT) containing user-programmed PWM values. The flexible LUT-based architecture enables
the user to program a smooth nonlinear fan speed vs. temperature transfer function to minimize
acoustic fan noise. Two tachometer inputs allow measuring the speeds of two fans
independently.

The click carries a 10-pole terminal block, that allows easy connection for pairs of two, three or
four wire DC fans, on the standard way of connection via PWM, TACH, GND, VFAN lines.
