PC Heating and Buzzing

[Kbatu]

Hello Tom's Hardware community. Recently i formatted and cleaned inside of my laptop due to slowing downs. After a month of two, my laptop started to overheat and make buzzing sounds from the speakers. I have attached (linked) the temperature values of my PC. (Running programs are Paint, Dota2 [a game] and teamspeak.] The heat of my laptop even heats up the room. My questions are what is the thing with the high Temperature and why & how can i stop the buzzing sounds, overheating?

My laptop is Samsung NP300E5C

Those temps may be a little high, but not alarmingly so; my guess is that the system fan is dead and the buzzing you're hearing is it trying to spin, and failing. This would also explain the extra heat. I would suggest replacing the fan to see if that helps; link below to one on Amazon, but you may want to shop around for the best price.

Hi, and sorry for late reply. I went off to holiday and totally forgot about my pc and my post, sorry again. I don't think my fan is dead because i can hear it right now and nearly always. And the buzzing comes from the speakers, not the laptop itselft.
