Is my Dell about to explode?

In what seems like a bizarre state of timing, my Dell seems to be telling me to hurry along with my plans to go and build a new PC as since the other night it's been making a rather awful din.

 

One of the fans seems to be chugging along; clearly it's trying very hard to do something. There's a big bit of green plastic hiding something inside the casing, and my noisy culprit appears to be behind there. Is there any easy way to remove that green shield? It's directly beneath the PSU. The fan seems to be ok, but it may just be a little loose and rattling against a part of the casing.

I think its the fan on the motherboard controller, but I might be wrong. As long as you lift it straight off it should be ok; its basic job is to duct heat to the outside. At home I've got some software that speaks to the BIOS about fan speeds and internal temperatures. I've forgotten its name, but it sits nicely in the tray and tells me if things are all ok or not. I'll post what it is and where to download it tonight.

So there's a danger it could be the heatsync fan having problems? If it is, how dangerous is it to keep running the PC do you fellas think? Again I don't think anything is dead, but something behind there certainly seems to be on its last legs as you can hear it struggle now and again.

 

I'll have another go at trying to take the shield off again in a little while. The only tabs I can visibly get to are the two that connect to the back of the case.

PS: Iain, when I build the new PC in a couple of weeks you may hear cries of help coming your way. :green:

Fortunately, the P4 is normally pretty good at temperature management, and will shut down (or just crash Windows if you're unlucky) well before the point of permanent damage. Those infamous videos of an Athlon melting itself were done with the temperature monitoring broken, its not normal. Its probable all you need to do is force that green cover off and replace the fan with a nice shiny new quiet one; a bearing or something is probably causing a rattle in it.

No problem - schedule it for a weekend and I'll even come round and do it, bag of discs in tow.

Right well I finally got the green shield off with my Hulk like strength. The main fan at the back was loose as I knew, and I was able to fix it back into place properly, but still the noise persists. I don't know if it's that fan showing its age then (it's still working), or it?s the heatsync making the noise.

Well, the program I run on my box is the rather sensibly named SpeedFan. It'll automagically detect what you're running on, and you get nice graphs of fanspeeds and temperatures, along with a nice display of the CPU temp in the taskbar when minimised.

 

Highly recommended for anyone vaguely paranoid about their PC's reliability, I can tell you.

Stop each fan until your find the one that is causing the noise and the replace it
