This article is about the creatures. For the 2015 film, see Minions (film). The Minions are small, yellow, cylindrical creatures, who have one or two eyes. They are the signature characters of the Despicable Me series. They bring much of the comedy in the film, and they are known as the scene-stealer of the movie. Frequently, they speak in an incomprehensible language, called Minionese, occasionally switching to English.
Leaving your fan on will not cause a cold/sore throat. A cold is cause by airbourne viruses. I suppose a fan can circulate the air in your room a lot more than normal.

A thermal fan clutch is engaged on a cold startup because the fluid drains into the working area when the engine is shut off. The fan clutch will slow down shortly after startup as a result of a pumping action produced by a difference in speed between the shaft and the body of the clutch.
