Gemini C71K-400 Operating Temperature Too Hot Causing Reboot?

Mine's about the same, it's not the temp, it's the software!

You could put a little fan there, but if you stress it, you can crash a Gemini.

Try playing with the 4k DTV channels, like 105... that will usually kill it after a while... it will run, then start stuttering, and then reboot...

I think the temperature is causing the connection issues until I hear from a few people who have zero connection issues and their Gemini temperature is over 140 degrees can share their experiences.

From the device specifications:

Environmental Requirements
• Operating temperature: 0° C to 122° F (0° to 50° C)

For what it's worth from ChatGPT and is typical of all electronic devices: 

The maximum operating temperature for a DIRECTV Gemini C71K device, like most electronic equipment, is typically around 40°C (104°F). Operating the device at temperatures higher than this may lead to overheating and potential damage or reduced performance. It's essential to keep the device in a well-ventilated area and avoid exposing it to extreme heat, as excessive temperatures can have adverse effects on electronic devices. If the device becomes too hot, it may automatically shut down or display warnings to prevent damage from overheating.

I recall Genie clients, especially Wireless ones like the C61W, easily reaching temperatures of 140 degrees Farenheit and still functioning fine.

If you are experiencing reboots or issues with your Gemini, it could be an issue with your specific Gemini, or a more widespread issue with firmware.

i used to have my DTV DVR on top of my Denon, and both warm, so bought one of those usb-powered laptop coolers and put it between them (they are thin and flat..

my cabinet has a permanent muffin fan exhausting it.

By the way, for what it's worth, CHAT GPT is worthless here... we don't even know where the temp is measured, could be the on-chip temp from the CPU, or some other area. Normal CPU's in a fanless environment are designed to run hot. I have not looked at this processor specifics, but it's most likely an ARM.

Many ARMs are tested at a core temp max of 120C, that is 248 F.

Most modern designs are also designed to throttle CPU speed if the system is overheating.

So without knowing where the temp is being measured, and what the design spec is, it's merely speculation.

My 12 core PC normally runs at cpu core temp around 70C or so, that's 158F, and the temp warning goes off at 90C I think.

I'd seek some concrete data.

Newer DTV receivers do have a fan that runs only when the temp gets to high.

The Genie 2 has one in the base, but I don't think the Gemini has one, but I have not seen an opened unit, but I don't see vents that would support a fan.
