the default Endeavor one did this, but I implemented it my own way. it's also got defaults built in, so I can slim my i3blocks config down a bit.
(i will not be using Rankine, I probably will use Fahrenheit. I think Fahrenheit is a better temp scale for human-relevant temperatures. I think Celsius and Fahrenheit are equally incomprehensible in terms of "what is normal/hot/too hot for a processor, especially a modern laptop processor?", and so I will use F there too.)
