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

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.

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.

I use my Sony cam for YouTube and this has dramatically helped with the sporadic overheating issues I saw a handful of times. I would highly recommend this item.

Works great for me. Florida heat is not nice to my camera. This keeps it working. Battery life could be a lot better, but lasts about 45mins on high.

Works very well. My only issue is the battery doesn't last very long. I might buy a second one for longer vlog shoots.

Keeps my Sony Zv-e1 from overheating, and is quiet. I can hear it, but the microphone can't.

Bought this to use with my Sony ZV-E10 Mark II and Sony A6400. It fits the ZV-E10 perfectly and works great. Ran it for 90 minutes recording full 4k at 24 fps and never overheated.Unfortunately, the ad states it fits Sony A6400 cameras. This does not at all. I need to find another fan for that camera.

This is my second Ulanzi camera cooler. I also own the 1st gen version with the suction cups. The new design of the Ulanzi camera cooling fan with the spring clip is so much better it was worth buying it again. The fan runs quietly and doesn't affect my audio. It has a good battery for long run times. It also runs on usb power. It keeps my a6700 as cool as my FX30. As for the new design it attaches firmly and confidently for all my shooting situations. Unlike the 1st gen with the lousy suction cups, I haven't had the new version fall off. Not even close to falling off. This new version with the spring clip is such a big improvement over the original version. If you need to keep your mirrorless camera cool this 2nd gen Ulanzi is a winner.
