A new notebook. I'm sure I haven't used Ben before. The desktop is not obvious because the fan is loud. That's because the hard disk is ringing, which is more obvious when downloading, especially when booting. The notebook cpu temperature is still relatively low, and the fan does not turn. Only when the hard disk is ringing can you hear clearly. This is normal. Look at the power indicator. The lamp with a column next to it is the hard disk. When it rings, it lights up and flashes. The hard disk will flash when it is spinning fast.
