Cautions• Passive cooling only works properly if the heat sink is sufficientlyventilated.44Never cover the heat sink on the underside of the system!Maybe you will find the heat sink temperature too hot, but remember:A cooling system depends on the difference in temperaturebetween "hot" and "cold". If there is no difference in temperature,there will be no cooling (because the flow of energy has stopped).Temperatures at 50° C at the heat sink (at room temperature andwith full load) are completely normal. See section 9.4, SurfaceTemperature of the Heat Sink.The heat sink is not too small! It works optimally and close to thelimit of passive cooling. Making the heat sink bigger (mass, area)would only have added more weight while barely increasing thecooling power. This is due to the laws of physics(thermodynamics).Attention: Use the table stand for ventilation:It is important that, for stationary operation on a flat surface, you alwaysset up the colibri X5 at an angle, so as to ensure the circulation of airwhich disperses the heat into the environment. Please use the suppliedblack aluminium table stand. This stand fits into the system case on theright below the tablet PC, so that you can always take it with you. Howto use the table stand is described in a separate chapter (see section 7,Getting Started).microport colibri X5 31
