What sort of temperature should you start thinking about cooling your fermentation at to stop unwanted flavours - thinking about S04 in particular

Temperature
thanks - mine was at 24' after being left over night so I've put the fermenter into my boiler with some cold water at the bottom and some ice... the temp has dropped to about 20' - I assume that after a day or two, once the fermentation has slowed, it will generate less heat itself and so I wont have to add any more ice
