Canon R5 II Overheating Solution for $13 - EinScan SP V2 - Shining3D

Summary

In this video, the creator shares the process of building an affordable, custom cooling solution for the Canon R5 Mark II to prevent overheating during long recording sessions. Instead of purchasing Canon's $400 cooling unit, the creator designs a prototype for around $13 using a fan and 3D-printed components. The cooling unit attaches to the back of the camera and effectively reduces overheating by funneling air into the vents. After testing, the prototype successfully cools the camera in just minutes, making it ideal for long-form recordings like interviews or YouTube videos.

Takeaways

• 😀 The Canon R5 Mark II can overheat when filming for extended periods in 4K with C-Log 2, specifically after 45 minutes.
• 😀 Canon offers an expensive $400 cooling unit, but the creator decided to build a much cheaper alternative for around $13.
• 😀 The video demonstrates a step-by-step process of creating a cooling system for the Canon R5 Mark II using 3D printing and a fan.
• 😀 The creator uses a 3D scanner (Ein Scan SPV2) to scan the camera and fan for creating a custom 3D model.
• 😀 The fan is designed to be attached to the back of the camera, using a funnel-like structure to direct airflow to the camera’s vent.
• 😀 The 3D printed cooling unit includes a holder for the fan, a funnel to guide air into the camera's vent, and a back cover to secure everything.
• 😀 The 3D printing process uses PETG filament and includes careful calibration to ensure the parts fit properly.
• 😀 Metal inserts are used in the 3D print to ensure the fan is securely held in place.
• 😀 The prototype successfully demonstrated the cooling effect, with tissue paper showing airflow through the camera's vent.
• 😀 Testing showed that turning the fan on high can cool the camera in just 3 minutes, and a lower fan setting can cool it in about 14 minutes without much noise.
• 😀 The cooling unit is designed for long-form recording, like interviews or YouTube videos, and is perfect for static setups but not intended as a replacement for Canon’s handheld cooling solution.

Q & A

Why does the Canon R5 Mark II overheat during long recordings?

The Canon R5 Mark II tends to overheat when filming in 4K with C-Log2 for extended periods, typically over 45 minutes, because it lacks a dedicated cooling vent, which can cause the internal components to heat up and trigger an overheating warning.

What was the cost comparison between the DIY cooling system and Canon’s official cooling unit?

The DIY cooling unit built in the video costs approximately $13, while Canon’s official cooling unit is priced at around $400.

What equipment was used to scan the Canon R5 Mark II for the prototype design?

The Canon R5 Mark II was scanned using the EinScan SPV2 3D scanner, which was set up with a table clamp and turntable to capture the camera's details and dimensions.

How did the design process of the cooling unit begin?

The design process began by scanning the Canon R5 Mark II in its default position, and then in a setup where the monitor was open to accommodate a fan at the back. The aim was to create a design that would channel airflow directly into the camera’s rear vent.

What kind of fan was selected for the cooling system?

A $10 USB-powered fan from Amazon was selected for the cooling system. This fan was chosen because of its affordability and availability, and it was designed to be mounted on the back of the Canon R5 Mark II.

What material was used for 3D printing the cooling unit parts?

The cooling unit parts were 3D printed using PETG filament, with a printing speed reduced to 50% for better precision. Calibration was also done before starting the print.

What was the main challenge during the 3D printing process?

The main challenge was installing metal inserts into the 3D-printed parts correctly. If this step was done incorrectly, it could require reprinting the parts, which would add significant time to the project.

How was the cooling unit tested after it was assembled?

The cooling unit was tested by setting up the Canon R5 Mark II to record in 4K with C-Log2. After 15 minutes of recording, the overheating warning was triggered. The fan was then turned on to see how effectively it could cool the camera, which showed noticeable results in just a few minutes.

What were the results of testing the fan at different speeds?

When the fan was set to high speed, it took about 3 minutes to cool the camera. On a lower, quieter speed, it took around 14 minutes to fully cool the system, which was more silent but slower.

What type of recording is the DIY cooling unit best suited for?

The DIY cooling unit is best suited for static recording, such as long-form recording for interviews or YouTube videos, where the camera remains stationary. It’s not intended to replace Canon's portable cooling unit for active shooting scenarios.
