benchy silk pla issues

Working with Sunlu Silk PLA (spool says 200-230 PLA+) and i've been having serious problems with any kind of overhang, any bridging and small bits at the top of a print (like the chimney). I've done a full recalibration, using prusa slicer generic pla settings with temps from default down to 205 and fan at 100%. The chimney is always melted, windows droopy, the bow is having separation issues, most corners with any overhang are kinda rough and the port side has significant ghosting from the deck. Lowering the temperature sealed up the holes in the roof and deck but the separation on the bow got worse. From the guides i've seen it look s like i'm having overheating issues. Ideas?

melty af

Hm even at 190 it's melty af. Is my thermistor malfunctioning or do i need to turn it down even more?

Test with different brand of filament, the you can see if it is the sensor.

Try to print with even lower temperatures.

Did you test of to much water in filament, extrude by hand and look if it bubbles.

trying another color

Doing a print with prusa silver pla right now and it's perfect so far. Any suggestions for the silk? Try going lower than 190?
