Hello,

I recently added two new 1TB hard drives to my Dell Dimension E520 (XP-SP3) PC and upped the RAM from 1GB to 2GB.

Now, whenever the PC starts working on anything like streaming video, downloading big files, virus scans, opening big spreadsheets etc the fan on the power supply goes into overdrive. I'm assuming its the power supply because it sounds too large to be the cpu fan. It makes a hell of a noise, it doesn't sound faulty noisy but just like it's working at full power. It makes using the PC annoying.

Is this something I have to live with because this PC is not really built for such large hard drives or can I upgrade to something better and quieter?

There is a good chance it's not your power supply fan but your rear exhaust fan(assuming you have one). What type of computer is this?

I've never heard of an exhaust fan on a PC before, what is that?

I have a Dell Dimension E520, the spec is here:

Well, what fan is it? Pop the side of the case off and have a look/listen instead of having us blindly try to play "Guess the FAN!". Normally "Guess the FAN!" is fun, but not over the internet.

Dimension E520 Processor Fan

It looks like the CPU fan is larger than the power supply fan and is also used as the front intake fan. It is probably the one that is making the noise. Clean the vents first, then make sure the heat sink is fully seated on the CPU and reapply the thermal paste.
