How it's done
What our technicians do, what it requires, and how to tell you need it.
For a full replacement job, we fully disassemble the cooling path, clean out accumulated dust from the fan blades and heatsink fins (the single biggest real cause of creeping temperatures), remove the old dried-out thermal paste completely from both the CPU/GPU die and the heatsink contact plate, and apply fresh paste before reassembly.
Dried-out factory thermal paste is one of the most common causes of creeping temperatures on a laptop that is otherwise healthy — we always clean off the old compound fully before applying fresh paste, rather than layering over it.
Typical time: 30–45 minutes
The model
