Looking after your computer is not just about software updates or careful use, but also about what is happening inside the device. Over time, dust builds up around the cooling fan and heatsink. The fan may still spin and sound normal, but the dust prevents heat from being carried away from the processor.

As a result, heat becomes trapped, temperatures rise, and internal components are placed under constant stress. Another common issue is thermal paste. This paste sits between the processor and the heatsink and is essential for proper heat transfer. With time and regular use, it dries out and loses its effectiveness. When this happens, even a clean fan cannot protect the processor properly, leading to overheating, sudden shutdowns, reduced performance, and, in some cases, permanent heat damage. The image in this post shows a typical example of internal dust build-up that we see every day. Regular internal cleaning and timely replacement of thermal paste can significantly extend the life of your computer and prevent costly repairs.
