![]() ![]() Another preemptive technique to prevent damage is to replace the thermal paste regularly. The best way to do so is with compressed air in an open space. The user should also clean the fans thoroughly, since dust and debris can increase the ambient case temperature and impact fan performance. If any of them aren't spinning correctly, it's likely that they'll need to be replaced. ![]() They can perform a visual inspection of the cooler and case fans. The user can also do a lot in order to preemptively prevent damage from happening. Throttling is also commonly used to manage temperatures in smartphones and tablets, where components are packed tightly together with little to no active cooling, and with additional heat transferred from the hand of the user. For desktop and notebook computers, throttling is often controlled at the BIOS level. Throttling reduces the operating frequency and voltage of an integrated circuit or disables non-essential features of the chip to reduce heat output, often at the cost of slightly or significantly reduced performance. Before an overheating component reaches this point, it may be "throttled" until temperatures fall below a safe point using dynamic frequency scaling technology. A computer with thermal sensors integrated in the CPU, motherboard, chipset, or GPU can shut itself down when high temperatures are detected to prevent permanent damage, although this may not completely guarantee long-term safe operation. This can be improved by the use of thermal compounds to even out surface imperfections, or even by lapping.īecause high temperatures can significantly reduce life span or cause permanent damage to components, and the heat output of components can sometimes exceed the computer's cooling capacity, manufacturers often take additional precautions to ensure that temperatures remain within safe limits. ![]()
