That is pretty common.
You could take into a repair shop and see if they have a quieter fan that they could install if it annoys you.

Sounds like bearing failure in the fan itself. What has happened is that the sealed bearings which allow it to turn freely have either lost their permanent lubrication, or have been infiltrated by dust. In either case, fan failure is not too far down the road, and cooling is just as important to your PC as your car.
You can have a shop replace the fan, but it really is easy to do yourself. Open the case, unplug the fan were it connects to the motherboard, and remove the screws holding the fan. Take the fan to Radio Shack, or a good computer shop, and obtain an identical fan. Reverse the process and your in business.
Most PC manufacturers use the cheapest fans possible. Look for the fan with the best air flow rating in CFM, and the lowest noise level in dBa. It is nearly always possible to get a fan that has a higher air flow for better cooling, yet is actually quieter.
Pay attention to the RPM rating on the fan. The faster the RPM, the higher pitch the fan's noise will be. (Think mosquito) Lower RPM fans with a higher blade count and pitch are normally quieter and less annoying while having the same or better airflow.

Noise can be disturbing but as long as the fan does it's job you have no need to worry.
Have you tried to clean it?
There may be dust in the fan that causes the noise.. and when it heats up a bit it starts working smoother.
Or it's just getting old.
Buy some 'air duster spray' (what's the word? I'm a Finn. Help!) and spray the dust away...
Or buy a new fan. PC cooling fans are cheap.

Dry bearing in the fan can do this... 2 cures I've used...
If you can get oil into the bearing it might help for a while. Use sewing machine (light) oil. Make sure you have it unplugged from the mains for at least an hour before you investigate - the power supply can give you a 400volt kick which can hurt or kill.
If you can't, replace the fan with like-for-like or replace the power supply.
If the fan completely fails you may have a short time before the power supply melts itself down and (if you are lucky) stops working without damaging anything else.

Dealt with this before - the fan or fans are maxing on boot... so they get very noisy.
When software regulating the fans loads, they 'calm down' and reduce RPMs... not good not bad - some manufacturers screw up either in BIOS or other design parameters, and compensate with software that 'fixes' a fans misbehavior (gods I was the tech lead for one of those for a major 'puter company... )
Talk to your vendor if you're really concerned, particularly if this is a new behavior, not seen before... they may owe you a patch, or even a new fan assembly.
Peace,

buy an air duster (can-o-air) and blow out the dust on the fan. that may help quiet it up.
note: DO NOT TURN THE CAN UPSIDE DOWN WHEN DOING THIS. keep it facing upright, as the propellant will come out in arisol form.
to andrew: sorry, cpu fans dont work that way (at least when they are working properly). they rev up to maximum rpm in seconds; sometimes fractions of seconds. any noise that doesnt go away after 2-3 seconds can rule out the fan having to rais to maximum rpm.

I always thought this was really weird, but the computer guy at my former job told me to check for a driver update or a patch to fix it on the PC Manufacturer's website. I didn't do it, but he insisted that would fix the problem. You've got some good answers.

it's time to get a clean fan; they are low-fee, and easy to change (purely a pair of screws and a potential connector). Beats the heck out of having to change a processor that overheated while an old fan went undesirable :-)

I believe that's normal - the fan is making sense because it was just turned on, so it's starting up, just like a car engine - once it's "settled", it will become consisent and smooth.
I wouldn't worry about it!

It seems that your power supply fan is making this noise. it is time to change your power supply it has little cost for you. or if you are technical person that i am sure you are not. you can go to market and take power supply fan and change. this thing i don't suggest.

take it in to get cleaned,could be dust built up in it. I periodically vacuum the grates and it sucks some dust out,but DO NOT open the computer,it could void your warranty and cause damage.
