Re: Vostro - Noisy Fan at boot

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.

Why would you keep starting and rebooting the machine? That does more damage than the fan noise ever will.

The fans are originally designed to run at full speed. The reason they start fast and then slow down is because of the way the control circuit is designed. They run up to full speed as a test of operational current. Say there is a big hairball in one. When it turns on the machine will discover that the fan isn't working and shut down due to the sudden current spike and lack of tach signal from the fan. It also will throttle the fans back until the heat inside the system get to the trip point, at that time the fans will speed up to cool the system. Without that higher speed ability you WILL cook the system. It is a protective measure that also audibly tells YOU that " Hey see the fans WORK". I wish many of the other models did the same. What would worry me is NOT hearing those fans when the machine first starts up.

Bull! - My previous PC Dimension 2400 bought in 2002 fan never were loud (when booting up or at any other time) and went like a dream all these years, no overheating or anything. Everybody used to comment that when it was on they had to do a double take because they couldn't hear it!

So far at least 3 people has heard the fans when I turned on the PC and are saying 'thats loud should they sound like that?' .
