I have just got a Vostro 200 Desktop and have noticed that the fans (processor and case fan) are very noisy for about 2 seconds as the PC is booting up and then they quiten down to normal whisper (well nearly) speed. I realise its not a fault and I have heard other PC makes do this (like Compaq PC's) but I am just wondering why its designed like that? The Dimension 2400 I am replacing never did this the fan was always whisper quiet. Hopefully in the next BIOS update for the Vostro they might adjust it so they don't do this in a future BIOS update. Andy.
