One of the basic problems manufacturers often have to deal with is overheating of their equipment. The cooling system is essential to keep a computer, mobile or any other device at a constant temperature and therefore optimal performance. Otherwise, the device may stop working or limit some of its functions. This is the case with the Canon EOS R5, which does not allow 8K recording for a long period due to the high temperatures reached by the processor. Unless, of course, you incorporate your own cooling system.
The Canon EOS R5 cameras released in July this year allow recording in 8K resolution. However, due to the large amount of data that is captured in this mode, the camera quickly rises in temperature due to the work that the processor must do. Initially Canon recording limited to just 20 minutes and then you had to wait about two hours for the temperature to drop and to be able to record again in 8K for about 20 minutes.
This limit makes all the sense in the world and rarely is a casual user going to record that long in 8K continuously. Nevertheless can be a headache for some professionals who seek to get the most out of the camera. On the DIY Perks channel they have shared a video in which they explain a solution: cool the camera yourself.
Ingenious, bulky, functional
As shown in DIY Perks, it is possible “bypassing” the 20 minute limit by modifying the cooling system of the camera. Realizing with a thermal camera that most of the heat was coming from the processor, he decided to open the camera and find a way to dissipate the heat from there.
The processor is located under the power plate and next to the rear panel of the camera. That is why he decided to add there a copper foil next to the processor to better dissipate heat. The sheet was in contact with a water cooling system that constantly extracted heat from the area. It is a very bulky system and certainly not recommended, but the fact is that it works, the camera stopped heating up.
Even though the camera no longer warmed up in the same way, it kept stopping 8K recording at 20 minutes. This was due to a software limit imposed by Canon. However, the limit has disappeared with a recent camera firmware update in which Canon changes the way it monitors temperature. Result? The camera record smoothly in 8K for over four hours in the DIY Perks tests.
In subsequent tests he modified the cooling system to make it more compact and with a single fan attached directly to the chamber. It indicates that it is not as effective but it still allows recording for much longer than the minutes offered by Canon by default.
Making these changes to a technological product is certainly not recommended. It can cause problems in the guarantee or the deterioration of the parts not only due to their modification but also by forcing the camera to work at a much higher performance than it was designed for. However, it is a clear example of how much cooling can affect the performance of a computer electronic. Hence there is research to add liquid cooling to the chips directly or Xiaomi has created a mobile cooling accessory.
