Router 7606 does not show the inventory for the Fan module

[jorgeacat]

I have a issue with a router 7606, specifically with  fan module, the LC go down because it does have sufficiently cooling , I changed the Fan module, the IOS, The power supply, and I still have the same issue, Besides the Router does not show the inventory or PID  for module fan, 

logg" system minor alarm on operating fan count"

Someone knows what could be happening,
