If a tachometer reading exceeds its limit (as defined by these registers) the corresponding bit is set in the Host and BMC Error

Status registers. The fan tachometer readings can be associated with a particular PWM output, but the tach errors are not

automatically masked when a PWM is at 0% or set to level that causes the fan RPM to be below the limit purposely. In order to

prevent false errors, care needs to be taken to make sure that the Fan Tach Limits are properly set. Errors are never generated

for a fan if its limit is set to 3FFFh.
