Few days ago got my Fitlet-H, which will work as 24/7 web server/file server. So last few days I did some testing limiting APU power consumption.
I tested values from 2000 - 10000 mW power consumption, and results were:
PassMark Geekbench 3 Cinebench R15 In heat test when I pushed fitlet-h to max, I got close to 70 degrees Celsius, but to get this temperature, I needed to do stress test for 8 hours

I did also test on 25000 mW power limit, but it was almost the same as 10000, so I did not include it in graphs. Hope it will be useful for someone, to get clear understanding of how capable this nice little black box is
