[arm-allstar] CPU Temp

[Mark Grigsby]

I have used peltier modules on other equipment n he past.  Here is an
article where an individual used a 15x15 mm peltier module and a small
fan to cool his PI.
There is a link to the peltier module from DigiKey in the article.
I would recommend a beter method o getting th required 3 volts for
this model, but that should be doable with some minimal external
components.

There is positive airflow in the rack but the ambient temp in the building is simply hot.  No hvac in the building. I have ordered the heatsink and will give it a try.
