Your product T11 unfortunately has many thermal design problems, causing the pc runs extremely hot and slow or freeze either,
pc runs first 5-10minutes fine but as heat build up inside the case, cpu thermal protection feature kicks in and throttle the CPU as low as 400-600mghz where pc become unresponsive. Even normal light working cpu temperature is above 60°C and under a bit load cpu quickly gets as hot as 84°C where thermal protection comes in, not to letting cpu temperature go over 90°C and burn itself, here I listed some of mistakes where made
1) thermal pad it used to heat transfer from cpu to heatsink
thermal pads are unreliable and has low thermal conductivity resulting CPU run hotter, Better way would have been metal shim with thermal paste.
2)Small heatsink used with black rubbery coating,
heatsink should be much bigger than this because it is fanless, it needs much bigger contact surface area to dissipate heat,
black rubbery coat reduces heat dissipating and shiny metal plate attached plastic casing does not help either.
3)Plastic top casing used with no ventilation holes and shiny metal shield/plate attached to it, does not help either because no path provided to hot air to escape.
plastic is cost affective material but because it is thermally insulated properties, it cause the chips inside plastic enclosure to get hot and hotter, metal casing would be best way to avoiding this and dissipating easily , also metal case itself become giant heatsink too. However if insist using plastic case then you should have drilled many holes on top of the plastic case to let hot air out.
I installed 40mm 5v silent fan on top heatsink, it works great keep cpu much cooler even under maximum load cpu barely exceed 50°C which is 30°C cooler than original design, massively increase pc performance and user experience, cpu able to give full power with ease . I hope it helps with your future products design, They get better and better, thanks
The computer screen turns black, or white, and nothing more can be done. Just unplug the power supply and switch it back on again.
