Will this $165 cooling fan solve the Canon EOS R5 / R6 overheating issue?

Accessory manufacturer Tilta has launched a cooling fan for the Canon EOS R5 and R6, which promises "high efficiency cooling" to solve the much publicized overheating issues affecting the two mirrorless cameras. 

Ever since they launched, both the Canon EOS R5 and Canon EOS R6 have been the center of heated discussion (sorry) regarding their recording limits, implemented by the manufacturer to prevent the cameras from overheating when shooting oversampled 4K and (in the case of the R5) 8K video.

There have been plenty of attempts to solve the overheating issue. Canon itself has two of its own, the first being the latest firmware that almost triples Canon EOS R6 record times, and the second being the rumored Canon EOS R5c (a more video-focused version of the R5 with a built-in fan). 

Plenty of homebrew hacks have been conceived as well, including an advanced watercooling system along with a more humble DIY solution involving sticky tape and a toothpick

Until now, however, the only "proper" off-the-shelf product has been a $400 heatsink from Kolari Vision – although, as a hardware modification, this requires both sending your camera away to be tinkered with and thus invalidates the warranty.

That's all changed, though, thanks to Tilta – an accessories manufacturer that produces gear for everything from mirrorless systems through to high-end Arri and Red cinema cameras. 

It has come up with the Tiltaing Cooling System for the R5 and R6: a $165 external fan module that mounts on the back of the camera body, which draws heat from the camera via separate layers of heat-conducting silicone, a conduction cooling board, and alloy cooling columns, before expelling the heat via a 7-blade, 5,000rpm low-noise fan (30db) and cooling panel. 

While the System is compact, slotting into the space created when the LCD screen is open (it can be affixed to the mounting plate or a cage), and is relatively light at just 195g, it requires external power from a USB – meaning that you'll have to add an external power bank to your rig, unless you keep it in your pocket or bag and use a very long cable. 

Titla also makes no promises as to how effective the device actually is, stating only that "this Cooling System allows you to shoot longer with higher resolutions and faster frame rates without overheating restrictions limiting how long you can shoot."

Still, for just $165 it's an option that many will probably feel worth the gamble. To find out more information, check out the Tiltaing Cooling System product page.
