What causes the outlet temperature of the centrifugal main fan to exceed the design value? What harm will it cause?

Transferred from chengkang: Under normal operation, the main air outlet temperature is proportional to the outlet pressure; the higher the outlet pressure, the higher the outlet temperature. But could the situation you mentioned be due to the filter at the fan inlet being partially clogged, or the opening angle of the inlet vanes being small, which causes all the work done by the unit to be used for heating the main air flow? It makes sense, but it seems incomplete and cannot solve the LZ problem
