Answer to: replace the hard drive, how do I connect Hard Drive thermal sensor?My iMac original HD has 8 pin, same as the new one I bought. Please see the image below, the new one does not come from apple. (The cost of new HD is USD 80 but Apple charge $200 to replace the same one) Note: I broke the top area off on the new drive I bought, as the Apple drive has a keyway and the new one doesn't so the cable won't fit. But even I connect the thermal sensor to the new one, the HD fan will also run at full speed after 10 mins. So I jump the third and the seventh pin to short the thermal feedback, so it will show 0C degree and the fan will always run at lowest speed. OOXO OOXO ( I jumped the Pin X) Then I download the software 'iMac Fan control' to control HD Fan. Maybe it's not the best way but it works well. The only thing I concerned is that I don't know the temperature of HD so I would know what time should I increase the HD fan speed.
