SmallRig 4815 Kühlsystem für Kameras

Finally, a fan that actually keeps the α7 IV cool during long takes; the quiet operation is a huge plus since I hate fan noise ruining video audio. No more overheating shutdowns after 20 minutes of 4K—this simple mount and fan setup just works.

The active cooling fan is surprisingly quiet even during long 4K recording sessions on my Sony, and it fits snugly against the body without blocking any ports. I've been able to shoot for over an hour straight without a single temperature warning, which is a huge relief for filmmaking.

My α7 IV used to overheat after about 20 minutes of 4K recording, but with this cooler attached I shot almost an hour straight without a single warning icon. It's a bit bulky, but the fan keeps things quiet enough that the built-in mic still picks up clear audio.
