How does dust actually slow down electrical devices?

Was just cleaning out my console and got me thinking about how the dust that gathers actually affects performance as it gathers on the outside of the device.

It affects performance indirectly as it makes cooling a lot more inefficient. Cooling is important because computer components are designed to work at a certain temperature range, and could be damaged at very high temperatures. Heat is produced more by components working harder. So computers are designed so that if they reach a too-high temperature and can’t cool down using their fans, they’ll instead start slowing down vital components like the processor or graphics card to prevent temperatures from getting too high
