i bought myself a new Android TV Box H98 Pro Plus which is really awesome in speed and flexibility.
This box comes with Android 6, but can easily be upgraded to Android 7.1.1, which i use now.
Problem with this box is the temperature. It gets way to hot.
So i thought about buying me a airvent to just have a constant flow of cool air to the mainboard.
This is what i bought on amazon an it is great. Did cost about 10 bucks, is very silent (just 18 dBA) and is powered by usb via the box itself.
Here is a picture of how it looks. I just put it under the box and temperature is as low as 40 degree celsius.
