LM96063 Remote Diode Digital Temperature Sensor with Integrated Fan Control speed RPM vs Tj temperature

Other Parts Discussed in Thread: DXP, LM96063

Hello , I am glad to use LM96063 to high power consumption FPGA for cooling FAN control . As I known this is automatically control the FAN speed when FPGA heat up . The FPGA DXP and DXN pin is diode sernsor pin which is linked to LM96063 to control the cooling FAN speed.

My first question is how I can know the relationship for FAN SPEED vs Tj of chip ? Is it right that the high Tj the chip , the high speed the fan?

The second question is if I want using a fixed FAN SPEED like RPM 500, how can I do I with setting ?
