Why is the cooler buzzing like crazy?

Question

Iron

It means that I installed a vidyushka, at the same time I blew the cooler. For a week I was tormented by the bluntness of the computer, then I reinstalled the system after fruitless attempts and then in the BIOS I came across a processor t 99 ° -100 °, and then it dawned on me that the fucked-up chest forgot to connect the cooler. They cut down the computer, put in the cooler. Now, at startup, it destroys the norms, but when loading and already in Windows (I’m resting from the penguin)))) it buzzes like I don’t know what. What to do, brothers?
