Keeping you, and your camera, cool when shooting intensive 4K shoots
If you've ever been in the middle of a perfect video take and seen that dreaded little overheating symbol pop up, you know the feeling. It's a moment of pure frustration that every videographer has faced. It can ruin a shoot, a crucial moment, or just the flow of a creative session.
At CameraStuff, we get it. Modern cameras are little powerhouses, shooting incredible resolutions like 4K, but all that processing generates serious heat. And when the heat is on, your camera, just like you after a long day in the South African sun, needs a break.
But what if you didn’t have to?
We recently sent some gear to one of our favourite creators, Thivhu Mamaila, also known as @thechocol8man, to get his honest take. Thivhu is a talented videographer and the founder of the production company Cakentea. He’s always pushing the boundaries of what’s possible with his gear. What he really wanted to get his hands on was a reliable solution to a problem he and many of us face daily: camera overheating.
That’s where the camera cooling fan came in. Specifically, the Ulanzi Camera Cooling Fan.
What is a Camera Cooling Fan, and Why Do You Need One for 4K Shoots?
Think of a camera cooling fan as a personal air conditioner for your camera's sensor and processor. It’s a small, external device designed to draw heat away from your camera's body, preventing it from reaching its critical temperature. This means you can record for longer, especially when shooting in demanding formats like 4K.

The Problem: When Your Camera Gets Too Hot for 4K
Before we dive into the solution, let’s quickly understand the problem. When you record video, especially in 4K, your camera’s image sensor and internal processor are working overtime. This generates heat. If that heat isn't dissipated effectively, it can damage internal components. As a safety measure, camera manufacturers build in a temperature cutoff. Once your camera hits that temperature, it shuts down to protect itself.
This is why you see that little red thermometer symbol pop up on your screen. It’s a warning, and it means you’re about to lose your shot.
This problem is even worse in certain scenarios:
- Shooting long takes for interviews, podcasts, or live events
- Filming in hot weather or direct sunlight
- Using your camera as a webcam for hours on end
- Shooting high-frame-rate or high-bitrate video
- Using cameras with compact bodies, which have less surface area to dissipate heat
For a professional like Thivhu, or any serious creator, these are daily scenarios. Missing a key moment because of overheating isn't just inconvenient; it can be a dealbreaker.
A Creator’s Take: The Ulanzi Camera Cooling Fan in the Real World
Thivhu put the Ulanzi camera cooling fan to the test in some real-world shooting scenarios. He didn’t just use it for a single video; he incorporated it into his daily workflow for a month.
In his own words, it "made my Sony A7 4 feel like a cinema camera."
That’s a big statement, and here’s why he found it so effective:
1. It Just Works, and It’s Easy to Use
Thivhu highlighted one of the biggest wins right away: the Ulanzi fan is incredibly simple to set up. It clips onto your camera's flip-out screen, and you're good to go. There’s no complicated mounting system or bulky rig required. This is crucial for a creative who needs to work fast and efficiently. The last thing you want on set is more complicated gear.

2. Powerful, Yet Quiet
The Ulanzi fan uses a powerful 5,000 RPM fan and a semiconductor cooling chip to actively cool the camera's body. Despite this power, Thivhu noted that it’s "barely making a sound." This is non-negotiable for videographers. The last thing you need is a loud fan buzzing in the background, ruining your audio. This quiet operation means you can use it for talking-head videos, interviews, or any project where clean audio is critical.
3. Reliable, Continuous Cooling
Thivhu tested the fan in three different scenarios:
- A long studio video shoot
- A talking-head video inside a car (a famously hot environment)
- Shooting food reels
In each scenario, the fan came through. He noted that every time he saw the familiar overheating warning from his camera, the fan "saved me each time." This reliability is what transforms a nice-to-have accessory into a must-have tool for a professional.
4. Smart Technology That Protects Your Gear
The Ulanzi fan has a built-in NTC sensor that monitors the temperature and keeps it at a stable 8° C. This is a crucial feature because it prevents moisture buildup on your camera. Cooling a surface too quickly without proper regulation can lead to condensation, which is a big no-no for sensitive electronics. This smart feature ensures your camera stays cool and safe.
5. Power for Days
The fan has a detachable battery, giving you over an hour of untethered cooling. But for those long, all-day shoots, you can plug it into a power bank or another USB-C power source for continuous cooling. Thivhu found this feature to be a game-changer, allowing his camera to "run the whole day" without fail.
Why a Camera Cooling Fan is a Smart Investment
The reality is, most of us don’t have the budget for a cinema camera that’s built to handle long takes and high temperatures. But with a simple, affordable accessory like a camera cooling fan, you can get a lot closer to that cinema-camera-like performance from the camera you already own.
For anyone who relies on their camera for video whether you’re a professional filmmaker, a vlogger, a live streamer, or a podcaster an overheating shutdown can be more than just an inconvenience; it can be a costly setback.
The Ulanzi camera cooling fan, or any similar quality device, is a small investment that offers a huge return in reliability and peace of mind. It’s a tool that lets you focus on your creativity instead of worrying about your gear.
Thivhu put it best when he said this gear felt like "a godsend." It’s that one piece of kit that you don't realize you need until you have it, and then you can't imagine working without it.
