I got your points. What I mean is my a4 temp are depend on outside temp. My country, morning & mid-day temp is about 35-40*C, and cooler in evening & night (25-30*C). I want to know, what is the maximum temperature range A4 Miner can handle? Thanks for help.

Hi everyone. I have got 3 a4 last week, these temperature is about 65-75C. The temp is going down 55-60 in the evening and night. Is it safe to run?
