*NOT a recall since that was only for the '78 model.
*NOT the radiator fan since I already checked this.

The CX500 is one of the best made by Honda. Many are used in courier service and accumulate six figure miles with little maintenance. The sound you are hearing is likely the water pump, maybe the weakest link in that V twin engine. Have you noticed any coolant leaks behind the engine on the left side? If it's leaked in the past a trail will remain on the aluminum case there. Does it seem to be making noise from that area? Regarding your other question about an oil leak. Is it possible that it's coolant, not oil? Oil leaks are very rare in the cx.

Cam chain tensioner broken.
Dont even think about the 1978 recall, it was a problem on ALL of them right up to the end with the automatic tensioner.
Is worse if engine is treated gently and not revved ( or allowed to lug around at low rpm (below 5,000) It was designed to be kept around 6,000rpm plus where it works well and lasts longer
Luckily it doesn't take too long to fit a new one although the engine does have to come out and rear cover, generator removed to fit it ( probably 3~4 hrs total even if tech hasn't done one before) Its actually easy enough to do yourself as long as you have a floor jack to re-fit/remove engine and a puller for generator rotor.

Is the 78 recall the one regarding the timing chain tensioner?
Even if your bike has the updated cam chain tensioner it could well be in need of adjustment. I believe the adjustment release bolt is on the back right side of the engine, you should follow the procedure in the repair manual to do it.

There are so many rotating and reciprocating parts in a motorcycle engine, there is absolutely no way to tell without hearing the noise and inspecting the motor!

May need a valve adjustment.
The push rods get very sloppy when the valve clearances loosen up.
