ASA and ABS definitely do better at elevated chamber temps. What temp is enough I can’t say but I still saw improvements when going from 50 to 70c. Higher temps also let you use more fan speed without the added risk of warping so you’ll probably see better overhangs even though the temps are higher.

Id start with adding some chamber temp sensors first so you can measure what difference you are making with the other mods.

Using 4 mm abs panels I saw about a 15c improvement by just throwing a fleece blanket over the printer, so that might be an easy fix if you don’t print large parts frequently. Although higher temps are also great for layer adhesion on smaller parts.
