DDR5 Memory Kits with Heat Sensors?


It seems that some RAM modules have a temperature sensor and some do not. I have some older Corsair DDR4 VENGEANCE memory from several years ago, and they did not come with the sensors. How common is it for new DDR5 memory kits to come with heat sensors? Any examples of ones that do or don't?

All DDR5 modules have a temperature sensor on the SPD Hub chip. This however doesn't measure temperature of the memory chips directly.
Additionally for DDR5 there is an optional possibility to have 2 more temperature sensors on the DIMM. But so far I've seen this only on some server (registered) modules.
