My cooling solution

What I have is a tiny 5v fan on one of the usb port opening, you can also use the gpio area opening as the vent.
My temps dropped fro 79c to 67c under 100% load on all cores. I’ve been building linux on all four cores and everything seems stable

Hi, ric96:

Which version ROM did you run when you got the temperate testing data? If you run the new official ROM Ubuntu-mate, the temperature will never up to 79 degree if without heatsink and cooling fan.

I meant to say from 76c to 67c
