Doesn't happen when stopped and idling?

Fan?
Either way just turn the radio up. -
A/C compressor? They can cycle at odd times if the refrigerant levels are low

If it is a regular ticking not related to engine speed it is probably a heater valve pumping coolant around or a Charcoal Filter vent valve pulsing fuel vapours into the engine, both normal function, can be improved by insulation between the valves and mounting points.

Hoping someone can give me an idea of what this could be..
I have a ticking noise from the engine compartment thats intermittent. I cant locate exactly where from unfortunately.
It started a few weeks back and at that time i thought it was connected to making a gear change as using the clutch seemed to make the noise start / stop. Now it does not seem to be connected to using the clutch anymore. At least i cant get it to start stop by using the clutch anymore.
Some rides it can be completely quiet. Some rides it comes and dissapears after a few seconds or halv a minute or so. Or its there until i restart the car at which point it can be silent for the entire next drive or not.
Sounds like a clock more or less. It goes at a steady pace and the rythem is not connected to the revs as its constant regardless of rpm.
Any ideas?
