No it's not normal however please try a SMC reset and see if the loud fan continues:

SMC RESET

Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

PRAM RESET

Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

As I have read the bulletin it seems to read to me to use the SMC as a last resort if all other tests and solutions do not resolve the issues. Its very much like having a miss in a engine. You don't just replace the engine you try and find the cause of the miss. I have just encountered some users who have messed up their computers more doing a incorrect SMC reset. Yes, sometimes as the bulletin states their is no other solution. I was just simply stating that their are other things and that in solving ones issues more questions need to be aksed and answered before suggesting any solution.

I see your point, well I guess we will just have to agree to disagree.

My Mcbook Air started with the fan noise last week, and the reset does not fix it. The battery is also going down twice as fast as before. Not watching videos or anything, but I do have it hooked up to power source and external screen, which has been the case for the past 2 years. Is there any way of knowing what the Mac us running? It must be running something in the background, but since there is no Ctl-Alt-Del in the Mac world, I don't know what it is running. I tried app IStat, and that brought in a virus and other garbage apps which I did not want. Are there other reliable diagnostics tools for Macbooks?
