Loud cpu

One more question to put out here, my cpu is making a lot of noise esp. when
looking at video or having more than one window open. -It is very loud(more
so than an old air conditioning unit!), Does anyone here know what may be
causing this and how I may be able to change it? Thanks-

I'm sure that the CPU is not making any noise at all.

The CPU is a small chip within your computer, not the computer itself.
It has no moving parts, and can not possibly make any noise.

There are only two possible causes:

1. A fan

2. The hard drive.

Open the case and blow out any accumulated dust with a can of
compressed air (do not use a vacuum cleaner). If the problem is a fan,
that is likely to fix it.

If it's the hard drive, it's a sign of impending failure, so be sure
that you have good current backup and get ready to replace the drive.

Or it can actually be the CPU fan doing its job under a heavy load,
running at 6,000 RPM or faster. OP should check that the heatsink/fan
is properly mounted on the CPU and that the cooling fins of the heatsink
are cleared of dust, lint and other debris. OP should also check that
there is good airflow around the heatsink/fan.

There can be several reasons for the loud noise but all are related to heat.
Have the system checked by a competent and trustworthy service provider.

I believe that's an oversimplification. Quite a lot of electronics
equipment makes a 60 Hz hum. My own CPU makes a distinct whining
sound when doing certain operations. (I know what the fan sounds
like, and it's not the fan.)

But if the OP is hearing something louder than an old air
conditioner, even allowing for rhetorical exaggeration, I suspect
it's the fan, with a bad bearing.

Your CPU chip *CANNOT* make any sound. It is not capable of acting as a
transducer.

If you don't mind educating me, how is that different from a
fluorescent light? Though I am way above average in sensitivity to
low-level sounds, I know that others can hear the whine of some
fluorescent lights.

I had thought the noise I heard from inside my PC was something of
the same order. If it wasn't the CPU, and it wasn't the CPU fan, and
it occurred during compute-intensive tasks, what could it be?
 
It's most likely caused by and electro-magnetic device (Transformer, ferrite
coil, etc.). To be down in the 60Hz it some device associated with the PC
power supply (which does increase in load the more the CPU is loaded).

That could make sense -- thanks.
