I’ll just have to do some of my famous redneck engineering, set up the shite portable in my bedroom and force the air direction towards the lounge instead to see if that holds the waft back. Probably not as well as the desk fan trained directly on it but eh.

I wish I could just remove and dispose of the problem. Or buy some bigarse ants online and release them into the wall to just take care of the issue fast. Having this happen in summer sucks.
