Aurora R5 Thermal Controls

Hi, I would like to use manual mode to control the fans. However, I don't know which fan should link to GPU sensor #1.

Here are more details for mu question:

For CPU cooler, there is a CPU sensor. So I linked them together.

There are also the Front fan and the Top fan. Should I link GPU sensor to the Top fan and ambient sensor to the Front fan?Thank you very much for your help, and I really appreciate it.
