PM for motherboards, memory, and adapters Motherboards, memory modules, and add-on cards (adapters) are all thermally sensitive devices. Ensuring that the computer is used in an area where temperature, humidity, and dust are controlled helps enhance their performance, extend their life, and reduce breakdowns. Make sure that all the cooling fans are working properly, that dust has not accumulated around them, and that the ventilation slots of the computer case are not blocked. To ensure that problems are minimized, regularly blow out dust from tops of motherboards, CPU fans, memory modules, and adapter cards. Cooling fans usually get jammed due to accumulation of dust around blades and walls.
