Hi,
The fans 1 & 2 in Module 1 on the Nexus5K are still experiencing the very high RPM and speed issue.
I have replaced the fan from another operational Nexus5K, and the fans are fine in the other Nexus. The replacement fans also have the same issues, so it is not a fan hardware issue.
There are no threshold alarms. the only log entry that is related to this is as follows:
%NOHMS-2-NOHMS_ENV_ERR_FAN_SPEED: System minor alarm in fan tray 1: fan speed is out of range on fan 1. 7950 to 12500 rpm expected.
I have provided the output for both the fan detail and the temperature.

Please let me know what can be done. Is that speed within acceptable limit.
Thanks

Usually this error message means that your have fan tray fault.
Is the same fan tray working fine on the other nexus?
Can you try reseating it again? Once you done provide me the following outputs:
show env fan
show en power in
show logging last 100
