I expect this thread or at least this question has come up before, so sorry if I repeat, but it is topical to me today. My study is waaaay too hot, and I have resorted to buying a fan. A first. So where is the best place to point the fan? Next to me? Oscillating? Not oscillating In the doorway? I have even read somewhere you should blow the fan out of an open window. Eh? That sounds too much like putting biscuits in the bin. So how do you get maximum efficacy from en electric fan?
