Hi there! Is [https://www.ifixit.com/Store/Mac/iMac-Intel-27-Inch-Late-2012-2019-SSD-Upgrade-Bundle/IF174-029?o=17|this the kit] you’re referring to? All of the iMac Intel 27” SSD replacement guides include steps near the end of the guide for installing the temperature sensor so that the fans will operate at the correct speed. I hope this helps, and happy fixing!
