Nikon Z8 Overheating update

Shooting apsc mode and 24p completely defeats the whole point of having a Z8

APSC or HD Mode on any camera I have never had an overheating problem. But 4k 24/30 this is a problem for the Z8. So I have also placed a fan behind my problem cameras Nikon Z30, Canon R8, etc. But the Z8 is different with the Hot Card Warning. I have seen it a couple of times when recording internally on the Nikon Z6II & Z7II. The Z7II will go to sleep if not being used and have to press the shutter button to wake up. So just in case Nikon messed up on stating Hot Card for the Z8 instead of overheating Thermometer on the Zf I placed the fan blowing on the back of this camera and it disappeared. On BOTH Cameras. It makes me suspicious when I see a fixable thing and it is mislabeled. Today when Car Vlogging my Sony ZV-1M2 overheated at the end but still the file was shut down in time before the camera was turned off. Same thing happened to the ZV-E10. With the Canon Cameras on the newer ones it give a warning thermometer when getting hot. That is why I like the Zf. So just blowing air across the camera will keep it from overheating even in Hot Climates where we are living now. In my case it is Texas. The problem is that I have taken out the SD & CFexpress cards and I still get a warning. I have never went into HD since this is 8k/4K. I did put it in crop mode a couple of times to test out APSC Lenses and using the 100-400mm telephoto lens with the teleconverters to see if it works which it did and guess what. No Hot Card Warning. But I was shutting it off now and then while setting up for another scene. As always Wayne you do the right thing and your way. I agree that you have to test it out yourself to find out what works and what doesn't. My camera has never been back to Nikon for any repairs. Now I am worried. But I do not have this camera in the studio anymore because of the other cameras that stay there in different studios around the house. So when I start seeing the problem with the camera I just turn it off and let it cool down a bit. I just been taking a lot of photos and few video recordings. So my workflow has not suffered. Great Investigating Wayne! Cheers!
