ULANZI Camera Cooling Fan Black New, Spring Telescopic Mounting Adjustable Mini Intelligent Cooling Fan Real-time Monitoring with Type-C Charging Port, Compatible with Sony Canon FUJIFILM Nikon

Works Perfectly, Only one Minor Flaw
To begin: Start by recording on airplane mode!!! Turning off network features, Bluetooth, etc will drastically improve thermals.This thing works insanely well. I can record a much longer time than I ever could on my A7IV. Heat dissipation is great. Plugging this in will provide it a bit more juice and help it run longer… Obviously.My only gripe, as well as other people’s, was how it falls out of the camera. You can find cheap rubber stickers on Amazon to put on the ends of this to add friction and prevent it from sliding around. This is a cheap game changer for me which keeps this device stable.There is some fan noise that will get picked up by the internal mics, but if you’re using external, no problems.This thing is versatile, plenty adjustable, and I can easily recommend it to anyone needing an improvement to the thermals on their camera.

Works really well
I bought one of these a while ago for my canon R6 which often overheats and shuts down while recording 4k videos.I have a camera timer that automatically stops and restarts at the 30 minute mark so I can record longer presentations with just a few seconds gap in the middle. But often using that, the camera would still shut down a little way into the second video from overheating.I added one of these ulanzi fans and the camera now can run continuously for a couple of hours without overheating whatsoever.I’ve never had to use the fan on the number two setting, and it keeps the camera pretty cool. It’s also very quiet on the first setting and doesn’t interfere with shotgun mics mounted on the camera. I haven’t tried it with the built-in camera microphones. I think that might be an issue though. But with an add-on shotgun it is not a problem .A little pricey for what it is, but for me it is well worth it. I also bought a second one for my other camera as added insurance, even though that one doesn’t overheat.Highly recommend this to anyone who has issues with their camera overheating.

Not secure at all
Great fan for cooling my Sony A74 it works great. I’ve gotten about an hour of constant use on the highest setting with one charge. The only problem is the spring mechanism used to secure the fan to the camera, it works until it gets the slightest little nudge and will immediately pop out. So if you use this product just be aware that it is not very secure and will pop out if its bumped.

After trying all the tips—opening the SD card door, setting AUTO temp to high, updating the firmware, and connecting a dummy battery to the V-mount battery—the only solution for my overheating issue has been the Ulanzi cooling fan. Now I can get the best out of my Sony A7 IV

It does cool my camera very well

A 4K 60fps a 600MB/s graba prácticamente sin limite en mi A7IV, tiene una duración de 1:30hr la bateria más o menos. No me fue necesario ponerlo en la velocidad 2, pero puede ser necesario en lugares con sol o calor. Superó mis expectativas. El material es completamente de aluminio, se siente de buena calidad, por el precio valió la pena, anteriormente sin ventilador no alcanzaba los 15min a 4k 60fps
