As the value is out of the working temperature range of BOXFAN, no model matches to your application.
(Calorific value calculation is possible)

2．Calorific value is UNKNOWN/Calculate from inner components

Calculate the calorific value in the enclosure as a rough standard by inputting equipment information.
Select a component from the "Electric components list" and input its rated output and quantity.

This information has been adapted from “Technical data No. 001-2018 Calorific value guideline for electric components in cabinets”
