Motherboard monitor... Winbond

In motherboard monitor, I see 2 active readings. Sensor 1 is Winbond 1. Sensor 2 is Winbond 2. Sensor 2 has a higher temp than Winbond 1. What components are these sensors reading from respectively?

Thanx,

A sensor in the motherboard for the lower temp and a cpu die sensor for the higher temp.
