What else spins with the engine?
Discussion
Let me explain further in numptyology...
As the loud pedal/throttle is pressed, the revolutions of the engine increase. If I were to place a connecting belt to the spinning engine and then a fan/windmill head to it, as I press the loud pedal, the engine revs would go up and the fan/widmill head would also rotate faster and get probably louder.
So, what I'm trying to say is, is there anything like the windmill head, that spins faster as the revs of the engine go up.
My reason is, that I have a noise coming from the engine bay, but it does not seem to be coming from the engine itself, but it does get faster and louder as the revs go up.
Any ideas or suggestions more than welcome, as this noise is starting to feck me off.
Cheers

I'm not sure of everything that is driven, but you have the alternator, air con pump and probably water pump... not sure if there's anything else.
It may just be a knackered tensioner or the belt itself.
I suppose there's also the gearbox/clutch, etc. it may be a clutch release bearing or something, I suppose?
Also, certainly in mine anyway, to a point as the revs rise, so does the vibration, and the clatter of the exhaust knocking on the chassis.
What sort of sounds is it? buzzing, screeching, humming...?

Well, it's a sort of a chaffing, sort of tinny noise.
Imagine a windmill's sails passing over a rigid piece of platic as they rotate and then the plastic springing back to position as another sail then begins to pass over it and so on.
Sort of like running a piece of hardboard along the railings of a fence, but more tinny.
Get my drift?

I like your style of describing things 
Worn Camshaft?? Try pin-pointing the the area the noise is coming from. try using a piece of old broom handle as a 'caveman' type stethoscope, hold it against your ear and push the other end on the engine.
How would a worn camshaft emit this type of noise?Worn Camshaft?? Try pin-pointing the the area the noise is coming from. try using a piece of old broom handle as a 'caveman' type stethoscope, hold it against your ear and push the other end on the engine.
What I mean is, what would be happening if the camshaft was worn.
The engine pulls well and has recently been described as tight by a reputable indie.

If the vehicle is stationary, options must include: crank, cams, pullies, idlers, gears, water pump, oil pump, power steering pump, alternator, flywheel, clutch, various gearbox components.
Does the alternator have a cooling fan. If so it could be hitting the end of a cable tie or something.

Does it happen when the car is stationary?
If not, it may be the prop shaft rubbing on a bit of heat shield somewhere. Mine did that, the description was similar to yours.
My mate put the car on a ramp, jacked the rear wheels up and ran it in 1st gear. Then he could see/hear exactly where is was coming from, and fix it.

The alternator is positioned in a really neat and tidy place but unfortunately suffers from heat-soak from the surrounding environment. Bearings dry out. Perhaps you are hearing early onset of this?
As others have said, there are a lot of rotational parts but if you have a "fan" type of noise, look to the external components first. They are more accessible (obviously) and are more likely to be heard.
They are:
Alternator and drive mechanism
Oil pump
Power steering pump (have you checked that you have fluid in there? These can whine when they're pumping part oil and part air)
Aircon compressor
Cams and (I think) water pump are internal. Water pump bearings can fail but they tend to squeal when this happens. If you hear your cams, I think you've got bigger problems than just the noise.
Check all the drive belts too. I've heard a few vibrate through incorrect tensioning leading to a kind of whine, but not the fan-type noise you're experiencing.

How's the weather? 
It definitely happens when the car is stationary.
It definitely happens whether the clutch is engaged or not and whether its in gear or not.
The noise gets quicker (and louder) as the revs rise, but it doesn't sound like engine wear, it's more defined than that.
The car still pulls like a train and doesn't seem to be affected by the noise or the cause of the noise.
It's definitely fecking me off and putting me off driving it because it's so bloody annoying.
How long will the car run if I take the alternator out, and where is it located, or can I just disconnectt the alterantor drive belt?
Also, where abouts is the woodruff type key thing located?

Alternator in engine V under fuel rail. Not sure if you can remove the belt easily. If it's the key I think they are mentioning its on the shaft that drives the pump assembly running alongside the sump. I would assume you would need to take the engine out to get that assembly off but I could be wrong.
Other people on the forum will know more than me.

The easiest route is to first disconnect the air conditioning belt, on the front of the engine, by slackening the tensioner and unhooking the belt,then run it, if the noise is still there then refit the belt and remove alternator belt, by slackening the alternators fixing bolts, push or lever it down so the belt goes slack then "wiggle" the belt out, off the alternator then off the jack shaft pulley.
I can't imagine its anything to do with the woodruff key as this doesn't make any noise if it breaks ( someone wil prove me wrong now!).
The noise may be an actual belt coming apart and the strands "frapping" on part of the engine, have a good look around the rotating parts first Good luck.
