Methods and systems for controlling condenser/radiator airflow in a TRS are provided. In particular, methods and systems are provided to control a fan speed of condenser fan(s) of a TRS based on a condenser/radiator performance parameter, a traveling speed of a refrigerated transport unit, and/or a compressor discharge pressure a compressor of the TRS. The fan speed of the condenser fan(s) can be increased when necessary to limit a negative impact on TRS performance caused by a static pressure at an outlet of the condenser fan(s) or under high ambient temperature conditions. The fan speed of the condenser fan(s) can be reduced to reduce noise levels generated by the TRS when the static pressure at the outlet of the condenser fan(s) does not negatively impact the performance of the TRS or when the refrigerated transport unit is not located in an area with a high ambient temperature.
