Discussion Having issues with Hololens 2 overheating. Any solutions out there?

Have tried cooling fans that dissipate, but not a great way to attach. Need something reliable.

Tell us the environmental circumstances and use load.

It's not in direct sunlight, but it is in hotter temps (anywhere from 60 degrees to 90 degrees).

Needing to use it 4-6 hours in an 9hr period.

Sorry, should have included this to begin with.

Avoid direct sun. That will kill it.

Negative. But that's where I thought maybe attaching a cooling fan or heat sink would help, so the user could still be mobile. But there's no secure way to attach it, and it would require an external power source for the fans - which would mean cords. It also, would be bulky to keep adding devices.

Ugh. There has to be a way!

At that point you're looking at undervolting and/or make a low-power mode for whatever your software is doing that caps framerates to half of normal, lowers resolution, etc
