Since you are familiar with this, and this will be my first go at it, tell me if this sounds reasonably doable.

I'm going to see if I can find a simple chime/alarm/buzzer. I will then wire it into the cool circuit so I can set it to sound if a high temp is reached. Seems like a fairly easy way to incorporate an audible warning if something wonky were to occur.

What is your thought on this? Any suggestions?

Thanks.
