ADM1034 Thermal Monitor and Fan Speed (RPM) Controller The ADM1034 is a dual-channel remote- and local-temperature sensor and fan controller.
The remote channels monitor the temperature of two remote thermal diodes, which may be discrete 2N3904/6s or may be located on a microprocessor die.
The device also monitors its own ambient temperature.
The ADM1034 can monitor and control the speed of two cooling fans.
The user can program a target fan speed, or else use the look-up table to input a tempe
