I totally understand there is a mega computer in a matchbox and that it gets bloody hot, and has to be cooled...
But as the engineers at RED are used to create miracles, a much more silent fan would be really nice.
When shooting, it's really noticeable when the camera is recording and when in standby mode, so for shooting documentary, it's quite annoying your subject notices when you start or finish a recording, because they become more aware of what is being recorderd. When shooting narrative, if you would want to steal a shot, it's also quite noticeable. And when in a silent room it's just a bit annoying to have the sound of a vacuum cleaner the whole time :)
So I have no idea if it's possible, but when RED will start the Dragon update later this year, it would be really nice if they somehow would find a way to maybe also upgrade the fan to a much more silent one? No idea if it's possible given the size of the epic, but nonetheless is would be really nice :)
