After reading some horror stories about cracked tubes I added a Dallas 18B20 temp sensor to the water supply.

I have a bunch of Peltier chips and heatsinks and a small pc cooing radiator but so far the temp hasn’t come near 70 and its been a really hot summer. I don’t know if I’m going to need any supplemental cooling.
