Most probably you will get those temperature sensors below chip7, chip9, chip22 & chip24.
You can consider chip1 from any corner of the hashboard, no problem. Those chips will remain the same in every cases.
You will find temperature sensors are badged with some letter-code like- "
T451 97J" or "
T451 87J" or something random prefix but always started with "
T451";
