Hi Anil,
you can use this solution for wndr4700:

echo "disabled" > /sys/class/thermal/thermal_zone0/mode
echo "1" > /sys/class/hwmon/hwmon1/pwm1_mode
echo "0" > /sys/class/hwmon/hwmon1/pwm1

and write some script like in post Automatic fan control - Linksys WRT1900AC

UPD: cheched fan-control on OpenWrt 19.07.4
