Things that move inside laptops

1) cooling fan.
2) CD drive.
3) Hard Drive.

So it's a fairly limited range of things it can be. most likely cooling fan as others have said, but are you sure there isn't a CD in the drive as that can make a lot of noise.

I'm wrong about the Dolphin then Chuck. Are you sure?

It might be a Blue Fin Tuna with machine gun...

What do you mean CD in the drive?! I've not touched his flaming drive... It's definitely the blue fin tuna with a machine gun...

find the air vent on the side of the laptop and see if the noise corresponds with when you can feel air being blown out the vent, if it does then fan for sure.

it may just need a clean out, you could try sticking a hoover pipe over the fan inlet on the bottom of the machine and see if you can suck it out (ooo err!)

if it's not that, well lets just say I hope it is, as hard drive is all that's left if it's not!

thanks chuck,
right, the noise starts when you hear the fans kicking in, so will the hoover pipe on it sort it do you think?
i did have a feel for air being blown out at the vent when it started up like you said, but couldnt really feel anything.
thanks for your help chuck and everyone else too.

hoovering the fluff out (i did type fluff!) might help a bit, but if it's really noisy then it is possible that the fans bearings are shot in which case a new fan is the only option, a cheap part, a tricky job to do though! (but I wouldn't expect this on a 5 month old laptop)

download this

http://www.cpuid.com/...Monitor_115_setup.exe

install it and it will show you what the fan speed is when you run it, just leave it running in the background and check it when the noise starts, you should soon be able to tell if it's the fan.

chuck, the temp went from 41degrees up to 48, the fan and noise kicked in and the temp went back down to 41.
is that a bit high or is it ok?

ringbolt

hi nolaces
did anyone get back to you on the temperature thing in your laptop?
i ask because im keen to know what the average/ideal temp should be after clicking on the link that chuck fickens suggested.
