Compatible laptop models
This replacement CPU cooler fits Acer Aspire 5740G, 5740DG, 5340, 5738, 5340G and 5542G notebooks. It is a new unit supplied with the three-wire connector used for speed monitoring and control. The fan is designed to mount directly in the original chassis cut-outs.
Practical limits of the three-wire interface
The three-wire design reports rotational speed to the system but does not accept a PWM signal for precise low-speed control. Voltage regulation by the motherboard is the only way to vary the fan speed. Buyers who need four-wire PWM regulation should look for a different cooler.
