Hi, I am thinking of upgrading my 21.5 inch 2012 iMac with an ssd. I was wondering if anyone knew wether you need a new thermal sensor for the ssd once you have upgraded. Can someone please help?
Mark.
A thermal sensor is not required on 2012 and newer 21.5 iMacs for 2.5" SATA drive replacements/upgrades.

Hi M_W_D,
Don't install an internal SSD. Rather, use an external SSD and run macOS from that. For external SSD recommendations and instructions, please see: How to Setup and Use an External SSD as y… - Apple Community.

+1 on Jack's advice.
If you have the standard mechanical HD now, the speed difference between an internal and external SSD on a 2012 iMac is small enough to be virtually indistinguishable from each other in real-world use. Any difference would never be worth the considerable risk and expense of opening a computer Apple did not intend to be opened.
I am upgrading the ram anyway as it only has 8gb. I was going to upgrade the hdd to an ssd as internal ones are also slightly cheaper. I don’t mind the slight extra hassle as I will be removing the logic board anyway. I just wanted to know if I needed a new thermal sensor for the ssd and if the fan will ramp up.
I am upgrading the ram anyway, and I just wanted to know that if I did want to upgrade internally, would I need a new sensor?
I can't suggest on what parts may be needed for a non-user upgradeable/serviceable component.
Cheers,
