Report CPU temperature alongside water temperature
I know the main purpose of this program is to deal with the pump/fans themselves, but I do think it makes a lot of sense to read the CPU temp and report it in the same UI/indicator. It gives you a quick overview of how well the cooler is actually cooling (e.g. if you notice that the water is much cooler than the CPU, something is probably wrong, such as poor physical connection with the CPU/bad thermal paste).
