Re: Vostro - Noisy Fan at boot

See my other comment about fans. Really and truly... live with it. A couple
of seconds of high speed fan noise can't be that bothersome. And when you hear
the high speed fan noise at power up, you can be reassured that the fans are
working OK. Dell has done this with a lot of its models, but not the low end
Dimension 2350, 2400, 3000. Most recently I set up a Dimension 4700 for
someone. Same deal. Loud fan noise for a couple of seconds when the system
boots or reboots... Ben Myers

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.
