My CPU Fan is running all the time at full speed. How can I get the issue resolved?
The first thing to check is if your Processor is actually heating up. Instead of recommending you to go into BIOS, I would recommend you to download Core Temp. If the temps are not high (between 40°C and 65°C) then you might need to replace the whole fan. On a lighter note, I hope you haven't mixed CPU fans with GPU fans.
