Hi I want to get some more life out of my iMac before buying a new one maybe next year so I want to swap out the HDD for an SSD. I have my eye on the 256GB Samsung 830 I know it will be a bit of chew on but shouldn't be terribly difficult. However I am wondering as the current drive is 3.5" and the SSD is 2.5" will I need an adapter? Also read that the 2009 models switched out the temperature probe for a direct connector to HDD using its own temperature data. Without this, the fans will go flat out. So, do SSDs have the pins needed for this new cable? Will I need to get around the fan issue if not, by software? Any advice would be great. Thank you and hope you nice people can help.
