@muhammadha21836 could be an issue with the fan motor or with debris, that has collected on the fan blades or the air inlet. Time to disassemble your laptop. Use the [document|38763] to work on it. Page 35 will show you how to work on the fan. Clean the fan as well as all the air inlets etc. I would even consider changing it since it is a vital part of your laptop. Spending the money to ensure the laptop will continue to work for a long time, seems to me as a good investment. Replacement fans are readily available at many online stores.
