Live with it. For a couple of seconds or so, the fans run at full speed and
sensors monitor the current they consume when running at full speed. If the
current is below a certain level, the fans are not running properly and most
well-engineered systems will halt rather than boot up, to prevent overheating.

The Dimension 2400, though decently engineered for a budget-priced computer,
does not have all the engineering safeguards found in more expensive models.

The Vostro works out cheaper than what the Dimension 2400 cost at the time! - Its alright saying live with it, but I am also at the point of thinking that the fans will have a longer life if they stayed at a lower speed all the time rather than speeding up like this every time the PC is booted apart from that it gives the 'impression' that there is a fault with the PC as its starting and also the fact that its bloody noisy if I start or reboot the PC in the middle of the night or in the morning.

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.
