When using a Photoshop software package (for picture editing) the PC speeds up (similar to downloading) but since i finished using the programme, the PC is still making the noise, it is like the fan is working overtime, any ideas?
Is normal for the fan speed to increase to keep the system cool when it has more work to do. It doesn't cool down immediately so the fans stay at the increased speed until the system cools down again.
If the fans are staying on longer than usual then take it apart and get all the dust and fluff out of it.
Many thanks for the answers! But it is not the fan, it is the PC itself. Is was just described like the noise the fan makes when working hard! It is like i am permanently downloading with the hard drive working overtime. It has been like this for some 5 or 6 days, although I am only using the PC for the internet.
