[USB] The GFX100II can record 8K videos in superb quality. The other recording modes are also impressive: 4K at 60/s, 5.4K and more.

BUT: only on a tripod, and: without a fan, the camera stops after 20-30 minutes due to overheating.

With the cooling fan, you can record endlessly.


Would be absolutely great: unfortunately, however, it is not suitable for my use (as a video camera to record car journeys - the image stabilization is too poor for this).

But that has nothing to do with the excellent performance of the cooling fan.

And by the way: I ordered it from B&H in Switzerland: it arrived after only 2 days: absolutely top-notch!!!

[Black] Works great. You can adjust the fan speed in the Canon menu. This one does NOT have extended buttons on the grip, or a metal bar to attach a strap. Just be careful you purchase the right one!

[Black] easy install, near-silent operation. you can't get much better than Noctua when you take into account performance and warranty. these fans are worth every penny

[USB] I run a couple of NAS enclosures and put these underneath to give a little extra cooling. I won't be 100% certain until summertime but my M2s and regular spinning HDDs have been running nice and cool over the past few months.

[USB] The fan is a lot quieter than I expected (even on high). I film a lot in my garage and the Texas heat was really pushing the heat limit on my XH2. The cooling fan seems to help a lot. It does get a little hard to maneuver the screen if you have the fan on, and a microphone and power cable attached to the camera, but it is needed for the cooling capabilities so all in all a good buy.

[Black] I bought this scope as an upgrade to my etx 90. I felt I needed a bigger scope for deep sky objects. I have only had this scope out about four or five times and it is awesome jumping from a 3.5 in to an 8-in scope let me tell you.! I was worried about not having tracking but it's a different type of experience it's a freedom that you don't get with a scope that has tracking . I like the fact that you just kind of grab it and look at something you don't have to push any buttons you don't have to program anything you don't even have to use the starsense, if you see something in the sky you want to check out grab it and move it over there. My skies are not very dark around here but I was still able to make out m13 more of a smudge due to light polluted skies but it was still cool, Andromeda Galaxy looked real good and of course the moon Saturn and Jupiter looked amazing, I needed a filter for the moon, it way too bright. The scope is not very hheav to move especially if you separate the base carrying them out one at a time is fine. I like the knobs to adjust the tension you can get it just right. The starsense works good it's accurate to the point where it will put the object in or near the field of view of a 24 mm eyepiece but I think I need to align it better. We did try a little astrophotography using a Sony crop sensor camera in the 2-in section of the focuser ( we did not have enough focus adjustment using the 1.25 adaptor) and we took a real nice picture of Saturn. If you are on the fence go for it you will not be disappointed

[Black] Great fan. So happy to have 4 pin so I can control with my bios fan pattern.

[USB] Nice product working flawless to keep my luxman r1070 cool.

[0.235 lb] The quietest fans I've ever used, keeps case cool. Well worth the money.

[USB] The R5 Mark II does get overheated in warm climates (95+ F or lower temps with high humidity) making this a necessary adjunct.


The fan is not temperature triggered. It is manual: off or on set through the configuration panels. When on, fan speed is selectable: high, medium, and low. Because of its architecture this grip does not function as a standard grip with duplicated controls. I have not used the Ethernet connectivity.


NOTE: When the R5 starts to get warm a temperature gauge appears in the viewfinder with bars going from green to red and when hot it will automatically shut down. Canon suggests turning off the R5 anytime you can in warm situations. This does work very well.
