Here are some actual results from recent testing using smaller ice blocks
Ice blocks were made using plastic containers that Cascade Dishwasher tablets come in (free).
Oat was over 90 deg
Output temp low 40deg ( important)
Airflow over 28 mph ( important)
DURATION before output temp started to rise over 2 hours.
We do this without gimmicks, just solid engineering
We do NOT count time once the output temp begins to rise even though you get quite a bit of additional cooling
