My pla prints curl no matter what settings I use, is it just the fans or am I using bad settings?

I usually print low and slow with pla/+ but no matter what, my overhangs curl. Ive tried multiple support, speed, and temp settings to no avail. Right now im using 190 nozzle, 55 bed temp, and full fans. Im not sure if i need to upgrade the fans or what. Ive already printed “upgraded fan ducts” from thingiverse but they seem to have no effect and might be worse than the stock version. any advice on settings or upgrades would be very appreciated.

Reducing the layer height can also be helpful. There are a few tips in this article: 3D Printing Overhang Curling - Settings & How to Prevent It
