Re: CFexpress card runs HOT...like REALLY REALLY hot that you can't even hold it hot

Having had that very card in hand.... temperatures were the same between that and the SanDisk. You have the Delkin as well. Are they similar in heat? I found that reader very warm as well. The SanDisk reader is much cooler but it is a different build.

Pulled my SanDisk CFexpress out of the camera yesterday and noticed it was hot within the camera as well...not as... But noticeable.

So.... Unlike SD cards, CFExpress cards are built to dissipate the heat created through higher transfer rates to the outside of the card. It is actually a new challenge in the storage industry because we could put heatsinks on SSDs when transfer rates increased as they were not meant to be a removable platform like CFExpress. The difficulty with CF Express is that air pocket between the card and camera and card readers. The heat has nowhere to go.
