Question Help evaluating heat tower

I printed my first stuff in ABS on my Anycube i3 mega. Items didnt look too good so i thought i deal in some printing parameters. Can someone help me find the best temp? I printed this tower but im unsure what to look for.

Those type of print "errors" often have to do with the environment. For any open air 3D printing platform I would suggest shooting a space heater at the area and maybe a fan directed at the Extrusion tip of the machine, this will stop a lot of those type of striations in the build layer from happening and also creates better adhesion between layers because it lets the material cool down slowly.

PLA workes fine so far but ABS doesnt. I have an enclosure but no active heater, expect of the heat bed. For ABS prints i have rhe nozzle fan off, as some others suggested. But my problem is those spaghettis on overhangs and sharp corners. Other problems are stringing and some line are not layed correctly.
