Amazon Fire TV Stick 2’s CPU runs hotter than 1st-gen, but dissipates heat more efficiently


One legitimate concern with the new Amazon Fire TV Stick 2 is how well it handles heat dissipation. Cramming in a quad-core CPU into such a tiny package, without any forced airflow, could be a recipe for disaster if heat isn’t managed correctly. Many 1st-generation Fire TV Stick owners know too well that it can get quite toasty, which is likely why Amazon under-clocked its dual-core CPU to 1Ghz, even though it was manufactured to run at 1.2Ghz. To determine how well the 2nd-gen Fire TV Stick handles heat, I’ve taken internal and external temperature measurements of the 1st and 2nd-gen Fire TV Sticks, both at idle and under a 100% CPU load stress test. I’ve concluded that, while the 2nd-gen Fire TV Stick’s CPU runs at a notably higher temperature than the 1st-gen Fire TV Stick’s CPU, the 2nd-gen Fire TV Stick dissipates heat better, which results in lower external temperatures.
