Faint ticking noise from engine bay only when warm, anyone else experience this?

I have been driving my 2014 Honda Accord for about six years now and recently noticed something odd. When the engine is fully warmed up and I am sitting at idle, I hear a soft ticking sound coming from somewhere under the hood. It almost sounds like a sewing machine running at low speed.

The strange part is that it disappears completely when the engine is cold. After the car sits overnight and I start it up the next morning, the noise is gone until everything heats up again. Then it gradually returns once the temperature gauge settles in the middle.

Oil level is good and I changed it about two thousand miles ago with the correct weight. No warning lights on the dash, no loss of power, and fuel economy seems normal. The car drives fine otherwise and pulls strong on the highway.

Is this something I should be worried about or is it just normal valve train chatter that comes with age and mileage? Curious if anyone has run into something similar on a higher mileage Honda or if I should book a shop visit sooner rather than later.
