We thought with the Sony A6500 that the overheating issue days with Sony would be over, but apparently not. Eterprising user, Brian Windle, over on Thingiverse, however, has developed a solution. It’s a 3D printed bracket that houses a couple of USB-powered fans to blow cool air onto the back of the camera underneath the LCD.

The bracket clips onto the Sony A7III eyepiece and then holds two 5v 30mm Raspberry Pi fans, wired in parallel, down below the back of the camera body beneath the LCD. This forces cool air onto the back of the camera, carrying away the heat as it escapes out the sides.

There are some caveats, though. You will, obviously, need some kind of USB power source, too. But a little power bank isn’t that expensive and shouldn’t add too much weight to the setup. He also says that while the fans don’t vibrate the camera and aren’t very loud, they are picked up by the internal microphone. So, you’ll want to use an external microphone or record audio separately and sync in post.

It’s a neat concept. How well it works, though, I’ve no idea, because I haven’t printed it (I don’t need to, I don’t have an A7III), although the description on Thingiverse seems to suggest that it does. There’s no word on what material he printed the bracket with, but given that it’s designed to deal with overheating issues, I’d probably avoid PLA and print it in something like PETG or ABS instead.

This isn’t the only Sony accessory Brian has made. He’s also created a Sony NP-FZ100 dual battery holderSony ECM-XM1 microphone XLR mountSony ECM-XM1 hotshoe mount and an A7III LCD hood.

      Your comment’s about a year out of date, Nermin. Sony’s the only one still clinging onto 8-bit. Everybody else offers 10-Bit baked or 12-Bit RAW now. :)

    My A7iii does get warm but nothing that would get me alarmed let alone really act on it by putting active contraption that adds bulk, requires power and emits noise. This is still a noble idea though for those who do experience this problem. And perhaps he could do something that could make Sony screens to fully flip out.

    The a7III isn’t having reported issues with overheating. That’s not a thing. Just because someone made a fan with a 3D printer, doesn’t mean that it solves an actual problem.

    This is what happens when sites like DIY pick up news from SonyAlphaRumors, without doing any fact checking.

      Funny… cause I found this article because my a7 III is shutting down due to overheating.

      Oh I just got both of my A7III overheat after streaming HDMI in 4K for 20min. Every A7III overheats after 20min of video recording in 4K. It is easy to replicate this issue. Sony is not doing good in preventing camera over heat.
