Okay, i went on my computer today and the pc was very loud (it is now too) i don't know where it comes from but now minimum speeds on fans equals the same noise as it was on fullspeed before and if i launch a game then a high pitch whining starts, when i close the game, then it stops. Here are my components what could make this noise : Cooler Master Hyper 212 Evo, Corsair Case fan x2 (came with the case) and amd radeon r9 270. Please help, the noise is very annoying.
