Personally I would say don't muck about with fans, go for an air conditioner. I realise maybe it's a bit much for some, but I would say £350 to never have a disturbed night due to the heat again, it's money well spent.
Get a mobile unit for £350 though. Does the job fine for me. Came out last week, will wheel it back up to the garage in September.
Hmm, not a bad idea at all actually. I’m sure there will be some nights where the fan just won’t cut it.
