Dave, After reading the last few posts, I ran a test with my Z8 + Sandisk 128GB CFe-B card.  I had run a test a few months ago recording using the data-heavy ProRes 4:2:2 10-bit format at UHD3840/30FPS.  It ran about 12-14 minutes before issuing hot card/hot camera warnings.  Just now, I tested again, same camera and card, but recording H.265/10-bit at regular HD1080/30FPS and it went so long...over 80 minutes...that I shut it off out of boredom.  The card and camera got slightly warm, not hot, and no warnings from the Z8.  Conclusion:  Low data rate recording formats (like regular HD 1080) generate less heat than the high data rate formats such as ProRes.

Thank you for all the responses.

I wish the seller of the camera offered Delkin Black but they didn't. I had to buy a CFexpress card from the seller of the camera so if bad luck struck twice the return would be easy. If the SanDisk/ProGrade 128GB card run warm but not excessively I'll probably slide it in my D850. I'm thinking the data transfer speeds of the D850 are slower so heat might be less of a problem with it.

Thanks again, you guys are great!

Dave
