Hello so recently i had to remove my computer to a friends house, and so i disconnected everything and moved it, but when i came back i could feel my finger switching something, so i had a look and found what out what it was that had been switched, Picture included. at the moment i have it set to A as i belive it stands for Auto but im not sure, as if i switch it to H it sounds like my fans are flying off with my computer itself
