There are a few things that can cause warping like that. It is hard to tell from the photo but it looks like you have a bit of elephants foot, so you might need to adjust your z.offset a bit.
Also you want to make sure that there are no air drafts in your room (open windows, doors, etc.) as they can cause the print to cool down to fast, which results in warping. If the printer is enclosed this should not be an issue.
If that does not work you want to look at increasing your bed adhesion by cleaning your bed and if necessary using a brim to hold the corners down.
You should not need to turn your fan off past the first couple of layers for PLA.

Pla and no fan? Pla needs extensive cooling, otherwise it will curl

And for pla uniform temperature would be best. Also you could run pla in a semi enclosed chamber, like close all lids and open the top one halfway. That helps in tall and narrow prints that just come off at some point.
