Abstract
A system comprising a fan tachometer module, a conversion module, and a pump tachometer module. The fan tachometer module is adapted to measure a speed of a cooling fan. The conversion module is in communication with the fan tachometer module, and is adapted to convert the speed of the cooling fan to a control voltage based on a predetermined ratio between the speed of the cooling fan and a speed of a cooling pump. The pump tachometer module is in communication with the conversion module, and is adapted to control the speed of the cooling pump based on the control voltage.
