The modification of Grey Garbage Guy is similar to my power cooling modification ; The garbage power source that has plagued me for several years was first changed to a fan free one, and the heat dissipation area was increased by using the CPU heat dissipation aluminum block picked up from the garbage heap. The effect was not good. The heating speed>the heat dissipation speed, which is hot for a long time; Finally, the fan is increased, and the voltage is reduced from 12V to 5V. It is no longer hot or noisy. There must be air flow for heat dissipation, and the effect is doubled
