This $400 Modification Could Reduce Your Canon EOS R5’s Overheating by 50%

The R5 might shoot glorious 8K video, but the recording times are limited by the camera’s tendency to build up heat. A company now offers a modification that it claims will double your 8K recording times and reduce recovery time by two thirds.

Kolari Vision, a company based in New Jersey and best known for its filters and camera conversions, offers a modification service for $399.99. The process has an estimated two-week turnaround and involves adding a new copper heatsink that transfers heat away from the processor and motherboard and dissipates it into the camera’s case. The design is completely internal and doesn’t affect the camera’s weather-sealing.

Kolari Vision states that its own testing increased recording times in an environment at 68° Fahrenheit (20° Celsius) from 23 minutes to 44 minutes. If the camera then has five minutes to recover, the modified camera can continue to operate for another 25 minutes as opposed to the 8 minutes achieved by an unmodified R5.

Of course, it’s worth investigating what implications this has for your warranty.

Would you pay $400 to improve the 8K recording time of your R5? Let us know your thoughts in the comments below.

Yes, I am going to open up my Canon R5 while losing my warranty only to benefit a bit in video. Just buy sony :))

So, taking the most expensive camera in the tier by half a grand to a grand and then DIY $400 solution? This seems like a risk to warranty.

There's no need to worry that there is a potential risk to your warranty! REST ASSURED that Canon will absolutely consider it null and void immediately.

Yes, this will kill your warranty. But who cares when you've shovelled a pile of cash into a Canon camera only to find that an inexpensive hunk of copper will "fix" the overheating issue. Hmmm.... Wonder if it was the engineers that killed this idea (or didn't think of it) or the corporate bean counters that decided that a hunk of copper was going to be to expensive to install and therefore cut into the profits. Naww. It must have been that this is just not a good idea.
