Next I attached the temperature sensor to the SSD, while keeping the cables as organized and compact as possible.

Here I also secured the SSD down to the iMac with some 3M adhesive squares. Since the iMac is curved right here I needed something that would hold it in place but was also thicker than most adhesives. https://smile.amazon.com/dp/B00O1WFF8U

I used four squares total, but I doubled them up. Stacking one on top of another twice; once on the back left and once on the front right.
