Question Pc noises normal or am I just imagining things

Just moved my pc into an office enviroment and im noticing sounds that I had never heard before, and due to suffering from very bad anxiety I thought my PC may have a fault, so are these normal noises or is something wrong, and if anything is wrong, would you have any idea what it is
There's some faint background sound that may be coming from a bad fan bearing but nothing serious.
