It should not cycle at all when ambient temp is below 40F. It will cycle when in defrost, and/or when in 'auto' and the temp is above 40. The high side temp sensor does have some affect on cooling fan operation. Higher than normal high side temp may indicate reduced airflow across the condenser, say when idling in traffic and the weather is warm. They would come on high in an effort to increase flow across the condenser.
