The Nikon ZR camera (order: B&H| WEX |Erhardt) can record continuously for up to 125 minutes in R3D NE 6K 59.94p without overheating, with auto temperature cutout set to [High], at 25°C/77°F, paired with an external power source according to Nikon’s official specifications:
This duration is for a single, uninterrupted take. The camera’s body is engineered for efficient passive cooling, including a chassis optimized for heat dissipation, which helps it outperform many competitors in its class (e.g., Sony FX3 or Canon R5 C in similar scenarios). Unlike some cinema cameras with active cooling (e.g., the RED Komodo with fans), the ZR relies on a passive design, which also keeps it lightweight:
If overheating occurs, the camera displays progressive warnings (yellow for caution, red for imminent shutdown).
ZRはファンレスなので、心配している方もいらっしゃるはず。個人的にも気になるので、どのくらい熱に強いか検証してみました。
日本の夏は暑いので25℃くらいの温度検証だと正直、春と秋で使うくらいにしか参考にならないので、快晴35℃の炎天下にカメラを置いてR3D NE… pic.twitter.com/IyiSieMWUK

Translation from the X post above:
“Since the ZR is fanless, there must be some people who are worried about it. Personally, I was concerned too, so I decided to test how well it holds up against heat.
Japanese summers are hot, so a temperature test at around 25°C would honestly only be useful as a reference for spring and fall use. So, I placed the camera in blazing sunlight at 35°C under a clear sky and shot at R3D NE 59.94fps. (Note: This was a test done by Ueda using a sample unit.) By the way, the iPhone 15 Pro that was placed nearby shut down due to the heat…
In the case of R3D NE 59.94fps, you can shoot for about 36 minutes with 1TB.
As a result, I was able to shoot a full 1TB without any warnings. Amazing! The Nikon ZR, being fanless, also ensures dust and drip resistance, which is great. It seems like I can use it with peace of mind. The surface temperature of the body, which got hot from direct sunlight, exceeded 50°C, but it’s reassuring.
Just to be clear, the camera itself didn’t exceed 50°C during shooting; the body just warmed up to over 50°C due to direct sunlight. During shooting, it only gets slightly warm. I’ll attach an image taken with a thermal camera”
