That noise you hear is your hard drive spinning. Also, if the programs you are using place high demands on your processor and video card, they might have fans which turn on to keep them cool.

The various components inside your PC generate heat and the harder they are working the more heat they generate. These include the CPU, RAM, video card and disks. Fans are used to remove the heat. Modern PCs use temperature sensors hooked to variable speed fans so that the fan speed is increased when needed and decreased when it is not. The fans can be quite noisy and the noise you are hearing is these fans being ramped up to cool your PC when it starts working harder.
You can monitor the temperature and fan speed using tools such as Intel's ActiveMonitor (http://www.intel.com/design/motherbd/active.htm). If you have a non-Intel CPU then your motherboard may have come with a similar utility.

Because your CPU has to work harder to open these large files or run something complex like a scan. When it works harder it produces heat. What you hear isn't the CPU, it's the fans that are cooling it down.

your CPU gets louder because your hard drive is working harder to open a program so more parts and motors are moving in the hard drive their fore it gets louder.

It is having to work harder to keep cool.
Variable speed fans are on some pc's that fluctuate with the temp to rotate faster as it works harder.
You may want to dust out your pc, if it is clogged with dust. Sounds unusual for that to happen unless your pc is either older or clogged.
