Modelled thermal performance and sustained processor power of the fanless Thinvent Micro 6 Pro Mini PC

Will the fanless Micro 6 Pro run behind your monitor, counter or kitchen screen?

  • All-day running with no fan: The Micro 6 Pro has an 89 x 100 x 20.2 mm closed 1 mm aluminium case. It does not have vents or a fan, and uses a quad-core ARM Cortex-A55 processor with a full-load power of 3 W. Our thermal simulation models the Micro 6 Pro standing on a desk in still air, and the RAM, flash and other chips on the board use 1.5 W. The processor runs its 3 W full load continuously in rooms up to 40 °C without slowing down.
  • How warm the case gets: Under a 3 W full load in a 35 °C room, the top cover reaches 53 °C. The base reaches 51 °C. The processor runs at 78 °C, below its 85 °C software throttling setting.
  • Hot kitchens and enclosures above 40 °C: In a 45 °C room, a continuous 3 W load brings the processor to 85 °C. The processor lowers its power consumption to 2.8 W, and the outer surface reaches 62 °C.
  • Placement behind screens and under counters: Air temperature around the device is what matters. This applies behind a monitor, on a point-of-sale counter, inside a digital sign or above a kitchen line. Leave open space around the device so warm air can rise away rather than banking up in a closed pocket.

Heat the case can dissipate across room temperatures

Heat the case can dissipate across room temperatures
The simulation models the Micro 6 Pro standing on a desk in still air, and includes 1.5 W of heat from the rest of the board. Before the processor reaches its 85 °C throttling limit, the case can dissipate 5.3 W of processor heat in a 15 °C room and 2.3 W in a 50 °C room. It dissipates the processor's 3 W full load in rooms up to 40 °C.

Hottest outer surface by processor power and room temperature

Hottest outer surface by processor power and room temperature
Steady temperatures at the warmest point on the Micro 6 Pro outer case across 25 to 45 °C rooms and 1 to 5 W processor loads. When a load needs more power than the processor limit allows, the processor lowers its power consumption to stay at 85 °C.

How warm the Micro 6 Pro body gets against processor power
The hottest outer surface temperature rises linearly with processor power in still air across 45, 35 and 25 °C rooms.

Surface temperatures of the Micro 6 Pro in a 35 °C room
Outer surface temperatures across the top cover and base under the processor's 3 W full load in a 35 °C room. The processor runs at 78 °C. The top cover reaches 53 °C above the processor, and the base reaches 51 °C at the corner board mounts.
