Or let the heat die down
I called one with my single forge. Turned it off for half a day. Now i run it a few hours, and turn it off a few hours have not seen one since. Everything you do in the chunk you are in builds the heatmap. You need to plan better. Are you running several forges, mining and running a workbench at the same time? Are you using loud guns as well, all within a short period of time? The chests are not doing it themselves, there has to be a huge build up of heat. Ive seen one screamer in 18, and NONE in vanilla 17. But i also dont mass run several stations at once, plus build and use guns in a single hour.
Even chopping trees can call one if you let the heat map build up high enough.
