Another Ticking, Fan Rotating Sound Question

[DECIM8]

Hey,

Ive got a sound comming from the drivers side, basically right under the pedals sounds exactly like a fan belt lose or fan itself hitting something. Ive got no idea how a clutch fan works but I know its most likely that.

Anyone got any idea what else it could be? If I pop the bonnet the sound is louder and distinctly like a roof fan spinning around at serious speed.

Anyone help in what it is? As i expect its a clutch fan how would a rectify this? Is it just a belt or perhaps full replacement?

Found this post too

"is it like a whirring noise that sounds like a fan cos if it does it would be the viscus fan...sometimes on the neo (happened to mine) the coupling gets jammed which means the fan stays on when accelarating. its the most annoyin sound. it kind of stops when you give it a boot up towards red line but yeh..im not sure cos your description is a bit hazy."

But the exhaust drones out the sound on accleration its really just pissing me off sitting at the lights next to another car as the sound bounces off the other car and into my window.

These things are realy expensive (i think someone mentioned 500+$) Use a VL one or use an electric fan - much, much cheaper

I actually have a brand new one from a vl with a few klms on it if your interested

You'll need a mate to test, but once the viscous fan gets to a certain speed it shouldnt go any faster, just keep revving the motor up high and see if it increases with rpm all the way up the scale. If anything it may of shift indicating wear

You can also just turn the fan with the car off and see if its fully seized
