Replace the device. S805 is obsolete. For under $30, get an Amlogic S905W (Android 7/9) or Allwinner H616 (Android 10) box – they run much cooler and support modern codecs.
→ Check for heatsink contact, add a small fan, or underclock using CPU Tuner (root required). Many users report temps of 75–85°C under load with Android 7. amlogic s805 android 7 hot
The MXQ S805 devices frequently have minimal heat dissipation—often just a small heatsink and no active fan. Replace the device
) along with a lint-free microfiber cloth to scrub away the crusty, crystallized factory thermal paste residue from the top layer of the main processor chip. → Check for heatsink contact, add a small
Apply a small copper or aluminum heatsink directly to the S805 chip with thermal adhesive.
The internal factory thermal block is often held in place with cheap adhesive tape that dries out over time. Open the plastic enclosure, remove the tiny metal plate from the processor, clean the surface with isopropyl alcohol, and apply high-grade thermal paste. Secure a larger aluminum cooling component to the chip to significantly increase the surface cooling area. Add Active Fan Cooling
. Running modern firmware on older hardware pushes the CPU to its limits, leading to thermal throttling, lag, and system crashes.
