Posted · Globbing / pressure in nozzle

No, I don't think so. A higher temperature will generally reduce the pressure needed to extrude at a given volume per second, and so may help to reduce the pent up pressure in the nozzle. But it also makes the plastic more runny, and so more likely to drip out of the nozzle anyway during slow moving parts of the print.

Printing faster increases the required head pressure, all things being equal, making it harder to control flow exactly on small areas.

Also, higher temperatures mean that it will take longer for the printed plastic to cool below its glass temperature, and increase the amount of heat transfer into the print during the time that the head stays over the print. For small areas, like the top of a pyramid, the main challenge is cooling the already printed parts enough before laying down the next layer - so generally cooler and slower is probably the best bet - and thinner layers, to minimize the amount of time needed for cooling.
