Claim Text:
1. A liquid-air cooling system, comprising: a fan device including at least one fan impeller powered by at least one variable-speed fan motor; a fluid cycle with a coolant fluid therein cooled by an ambient air flow produced by said fan device increasing a cooling capacity for the coolant fluid; and an automatic control controlling speed of said fan motor to maintain a temperature of the coolant fluid that is lower by a set amount in comparison to a desired default temperature value, said control comparing at least one actual temperature value of the fluid to the desired default temperature value of the coolant fluid to adjust the cooling capacity by varying speed of said fan motor as a function of current output temperature values of a machine unit coupled to said fluid cycle, the desired default temperature value being one of a machine unit temperature and a temperature of a component at the machine unit.
