Heat spreaders are high thermal conductive metallic materials used to dissipate heat from an IC chip in a semiconductor package. They are typically made of aluminum, copper, and carbon materials to increase their contact surface area. They also feature a variety of fins to improve heat distribution and cooling efficiency. The ram heat spreaders are a crucial part of the memory module to protect it from overheating.
Overheating is one of the main causes of a computer or laptop failing prematurely. When a device overheats, the components inside start to suffer from accelerated wear and tear and may begin to fail. Fortunately, overheating is not an issue with modern RAM. This is because most modern ram modules come with built-in thermal throttling, which will cause the ram to slow down when it starts to overheat. This is meant to prevent the ram from burning out, and it should keep the ram operating safely for a long time.
RAM manufacturers usually add heat spreaders on their ram for aesthetic reasons. They are often tall, elaborately shaped, and can be quite pretty. However, they are not necessary for a computer, and in fact, they can be harmful. They can interfere with proper airflow, and they can block the ram from the CPU heat sink.
In addition, the hea tspreaders are usually glued to the ram, which makes them difficult to remove. If you attempt to remove them, you can damage the ram chips. I highly recommend not removing them, and instead investing in a good ventilation system for your case.
