I've read that since the Plus didn't have a fan, it was somewhat common for it to overheat and have PSU issues. The last time I used one, I was 7, but I've recently acquired a new one that I plan to operate for long stretches of time in an already hot environment (>95 F), and I'm wondering if I need to be prepared for trouble. How concerned should I be about this ahead of time, and what are the recommended mods to keep it cool?
