Overheating Lumix DC-G9 and a G7 doesn't work with HDMI extender

I've got a couple of questions - a total newbie. I'm doing some live streams in my studio. Several rooms. We started using another room that I think is a little stuffy. Not a lot of ventilation. It feels OK but the camera keeps shutting off. I think it's over heating. We had a lamp that was pretty close so we moved that but 10 minutes later it happened again. Its a Panasonic Lumix DC-G9. I've seen this behavior before. I had thought it was because the screen was closed. So now even if I'm not using the screen I open it. But I'm not sure that's the problem. As a matter of fact when it's overheated before it was this specific camera. I have a few other G9s and I haven't seen this happen with the others. Is there another reason the camera shuts off that I'm missing?

So I was wondering whether there's a fan recommended that will keep it cool, if this is indeed the actual problem.

Another strange problem is I got a cheaper Lumix - G7 4k. I'm streaming from a studio, different rooms. I'm using an ATEM Extreme ISO. I'm using a Vanco 4k HDMI extender. For some reason the extender doesn't work with this camera.  All the other cameras are fine with it.  I tried different Cat6 and HDMI cables.  So either there's some setting I've missed in the G7 or it doesn't work.  It works otherwise so I've decided to not use it if I have to go a distance that would necessitate the extender. It has a mini HDMI port.  I made sure I had a 4k mini or micro HDMI cable.  No change.

Thanks for any help or suggestions!

Were you on 1080 or 4K? How long the recording had gone before automatic shut down?

I think it's over heating.

Rarely heard of overheating on Panasonic cameras!

We had a lamp that was pretty close so we moved that but 10 minutes later it happened again. Its a Panasonic Lumix DC-G9. I've seen this behavior before.

So it happened often?

I had thought it was because the screen was closed.

Do you mean LCD=OFF, evf=ON?

So now even if I'm not using the screen I open it.

Shooting with LCD or evf, AFAIK, would do little difference with overheating...

But I'm not sure that's the problem. As a matter of fact when it's overheated before it was this specific camera. I have a few other G9s and I haven't seen this happen with the others. Is there another reason the camera shuts off that I'm missing?

Might be a faulty camera?

If the situation repeated often, might worth to ask for service center's help.

So I was wondering whether there's a fan recommended that will keep it cool, if this is indeed the actual problem.

The heat is generated from inside the camera. Not sure how Panny works, but on GH5, this flagship hybrid model has a very large heatsink under the hand grip to deal with the heat issue making Panny cameras being one of the best to deal with 4K heating issue.

On lower spec models like G95/85 or GX9/85 etc, they use a relatively smaller piece of heatsink  (I trust it should already be very big for other systems?) on the back of the sensor.

I guessed G9 might use a heat dispersing solution in between that of GH5 (because on size-wise G9 can do so) and the other Pannys.

Therefore I am afraid a simple fan outside the camera might not be effective.

Another strange problem is I got a cheaper Lumix - G7 4k. I'm streaming from a studio, different rooms. I'm using an ATEM Extreme ISO. I'm using a Vanco 4k HDMI extender.

Just to have some context what is the ambient temperature?

Thank you al for your replies. Gives me "hm." I'll have to reply in more depth later. Yeah, this camera might be a lemon. And I'm wondering whether there's a setting I missed where it turns off after 20-30 minutes?

Does the camera completely shut off, or just stop recording?  From the G9 manual:

I have shot a full half hour of 4K video on a G9.  The camera was warm.  But it did NOT overheat.  If you have multiple G9s and just one "overheats" as you say, I'm not sure if that's really the cause but clearly that one is a stand-out.  I'd send it in for repair, if I were in your position.
