Temperate gauges and advice

Hi guys I'm wondering what are ideal temperatures to be running? I am set to 80" safety on antminer with a l3+.
I'm running
54 49 50 46 on pcb temp

59 56 54 53 on temp chip

No external fan currently used.
Just finishing the last few hrs of my first day mining on L3+

Will be installing Siemens 60 ka surge protection today as these are nice little machines that need to stay alive.

"59 56 54 53 on temp chip" is actually pretty low.
No idea about normal frequency but at 450 frequency i have ~63-69°C. Thats without AC or extra fans

I think I'm on 384 whatever default is for antminer l3+
Good to know thanks for feed back.

Yea 384 is the default
