Hi, I shall be replacing an iMAC's HDD with an SSD. I already researched about the procedure, and found that the iMac 9,1 (Early 2009 20" model) uses a heat sensor for the HDD. Do I need to attach this sensor to the SSD? If no, will this affect the iMAC in any way? Also, I am entertaining the thought of using a SAMSUNG EVO 850 with the capacity of 500GB, will it function properly with the iMAC?
