mounted old computer on new bike and making a strange new noise

I have a cateye velocity 5 computer that I had mounted on my old bike since 2007. I only put about 600 miles on that bike. Anyways, I noticed it was making an odd sort of electronic clicking/beaping noise. It is not the magnet hitting the sensor, I've triple checked to make sure. It is however making the noise when the magnet passes the sensor. I don't recall it making that noise before but maybe I had just gotten used to it or something but I don't think so. I did just reset it to put the odometer back to zero.

Anybody know why it could be making this noise? I might have thought it was normal if I hadn't used he same computer before.

Cateye (and others) computers use a reed switch in the pickup unit attached to the fork. The reed switch produces a faint clicking noise as the electrical contacts close when the magnet comes into close proximity of the reed switch.

My Cateye Strada makes a distinct clicking sound with every wheel revolution.

Yeah, and I think the change from steel to carbon fork is amplifying the sound. Hopefully I wont be able to year it while riding. I can probably try to put some kind of rubber padding between sensor and fork to muffle the sound.

If you don't have any rubber padding of your own, you could hit Performance, Bike Gallery (both on SW Hall), or Bike and Hike (on SW Canyon), and I'm sure that they'll be happy to give you one.
