the tower prints look fine.

the weirdest thing is the best temp is 220c - what filament are you using again ?
It's the ckeanest layer with no blobs.
That's pretty weird if it's pla.

Second weird temp issue with a creality machine today.
I'd be inclined to replace the hotend thermistor with a known brand and quality part.
There is definitely something seriously wrong with the temps that are being reported.
