Hello, I have lost my temp sensor cable and i want to make my own sensor with a 3904 transistor but I need to buy the connector and I don’t know what type of connector is it so i can search for. Can you help me with the connector type?
There were three. One built for Hitachi, Seagate and Western Digital hard drives. Please tell us you exact machine and what original Apple hard drive it had. UPDATE Sometimes the 2009 does not need the Thermal Sensor to preventive run away fan. Did you try it after you changes the hard drive? iMac 27" Hard Drive Temperature Sensor https://www.powerbookmedic.com/iMac-27-H… 24" iMac Hard Drive Temperature Sensor http://www.powerbookmedic.com/24-iMac-Ha…
