Perth gets hot. Notebooks get hotter. By late January every year our Perth workshop sees a wave of notebooks running fans full-blast, throttling under load, or shutting down in the middle of work. If your notebook overheats in summer, it almost always comes down to one of three things.
Reason 1: dust-clogged fans and heatsinks
The most common cause of notebook overheating in Perth is years of dust collected in the fans and heatsinks. Notebooks suck air in from underneath, push it across copper heat pipes, and blow it out the side. If those heat pipes are coated in lint and pet hair, hot air just recirculates — and the CPU/GPU has nowhere to dump heat.
Fix: full strip-down clean of the cooling system. We pull the fans, clear the heatsink fins, and put it back together properly. Our overheating & fan repair starts from $219.
Reason 2: dried-out thermal paste
Thermal paste sits between your notebook’s CPU/GPU and the heatsink. It transfers heat across the tiny gap. After 3–4 years it dries out and cracks, and the CPU starts running 10–20°C hotter than it should. Combined with a Perth summer, that’s enough to trip thermal throttling on every video call.
Fix: we replace thermal paste with a premium compound during the same fan repair. Most notebooks gain back significant temperature headroom from a clean + repaste alone.
Reason 3: a failing fan
Notebook fans have a hard life. Years of spinning at 5,000+ RPM eventually wears the bearings — you’ll hear it as grinding, ticking, or a sudden silence (the fan stopped working entirely). A failing fan means heat builds up with nowhere to go, and modern notebooks will throttle hard or shut down to protect themselves.
Fix: replace the fan. We stock common notebook fans and can source brand-specific replacements in 2–3 business days for less common models.
What you can do before bringing it in
- Run the notebook on a hard, flat surface. Beds and laps block the air intake.
- A cheap notebook cooling pad can help, but it’s not a substitute for cleaning.
- Update BIOS and drivers — sometimes a thermal management firmware fix helps.
- If it shuts down on its own, stop using it under load and book it in.
Notebook overheating repair in Perth, done properly
If your notebook overheats in summer, gets too hot to touch, or shuts down mid-task, book it in to our Perth workshop. A full clean, repaste and fan check is one of the most cost-effective notebook repairs you’ll ever do — it can take 5+ years off your notebook’s age.
