What to change:
Cool is a fan control CLI that lets you cool your CPU to any temperature you'd like.

Issue:
The wording is - of course - misleading. It is not possible to cool down to any temperature ;)
In addition you could change CPU to Mac internals, as the fans cool the entire internals not just the CPU.

Suggestions:

• Cool is a fan control CLI that lets you cool your Mac internals to an desired temperature.
• Cool is a fan control CLI that cools your Mac internals to to a given target temperature.

Reasoning:
I know this is just a different wording but the phrase "any temperature" implies that it would also work. Sadly for temperatures below a certain threshold this is simply not possible, as such you could implement a lower bound either hard coded or after a testing phase below which the program defaults to this value.
For example: 30°C as lower bound result in 0 RPM at room temperature.

doesn't work in m1

Details

The screenshot above basically explains it — when I run sudo cool, the fan speed display doesn't update (even though I can feel the fan working). It looks like cool.go has been updated since then, so maybe a new release is needed?
