Loud whine from laptop

[BlueFireZ]

So I've had my Sony Vaio VGN-FW235D for about 6 years now and it's served me well, and still works fine except for this one little thing, it makes a loud whiny noise all the time when it's turned on. I've read articles about how it could have to do with the hard drive or fan but I'm not sure about which. If someone could tell me whats causing this problem and how to fix it I'd greatly appreciate it.

If it is the HDD, you can usually test it by putting it under some load and see if it gets louder (the noise) but your fan(s) might be blocked by dust or something like that, or the bearings could just be dying inside of the fan.

I observed that if I let the laptop idle the noise goes down, could that mean anything? Heres what else I've observed: If I move large files around the computer makes a really loud noise, If i open a couple applications at once the computer becomes quite loud but not as loud as when i move large files though.

My theory is that it gets louder as the CPU load gets higher. Also, it's just loud in general (like all the time) but when I do certain things it just gets louder.

It could be both the fan and HDD but more likely the HDD. Try installing a program called HWMonitor and screenshot the temperature results:

I can't give a screenshot because it has to be a link from the web, but here is the temperature readings:

Value: 70, 69 celsius
Min: 62, 63 celsius
Max 78, 79 celsius

What temperatures are they for? The CPU or GPU?

The CPU (Its a dual core laptop), the Sony doesn't have a GPU.

Ok, well the temperatures seem fine for a laptop. Have you checked your Fan for dust? A hair or something might of gotten caught in it or just dust.
