Questions about night temp drop

Hello so I should receive my female ball python today, I was looking over this and I have a question, about night temp 75 or below, it's summer time, so I have a fan in my room and AC is set to about 75, but in the middle of the nights I look at the my temp, Cold side only, and it gets to these numbers, But these numbers do flucture up-and-down throughout the night, but she has her hot side, So she should be OK right?
Or is this more tords a person that Constantly keeps their temps at 75 and lower 247https://uploads.tapatalk-cdn.com/202...92de6af4e9.jpg

Should be fine. If you find it consistently gets too cool in your house to maintain cool side temps then you can add a second heat mat and additional thermostat for the cool side set to 78-80*.
