Over time the MacBook accumulates dust and the thermal paste dries out. That leads to overheating, loud fans and drops in performance. A timely cleaning brings the laptop back to factory behavior.
Why cleaning is needed
The MacBook cooling system is designed to efficiently move heat away from the CPU and GPU. But when the heatsinks are clogged with dust and the thermal paste has lost its properties, heat stays inside.
Signs it's time for a cleaning
- Fans run at maximum even when idle
- The case gets very hot during basic tasks
- MacBook got slower at the same workloads
- Frequent sudden reboots
- Last service was more than 2 years ago
What the service includes
- 1Temperature diagnostic before the cleaning (under load)
- 2Careful disassembly with flex cable disconnect
- 3Removing dust from heatsinks and fans
- 4Removing old thermal paste from CPU and GPU
- 5Applying new high-quality thermal paste
- 6Reassembly and load-testing
After a proper cleaning, temperature under load typically drops by 10–20°C and the fans get noticeably quieter.
How often to do it
For most users once every 1.5–2 years is optimal. If you do heavy video editing, 3D or gaming – once a year. If you work in a dusty environment or live with pets – more often.
Signs your MacBook needs cleaning
A clogged cooling system can be identified by several characteristic symptoms. If you notice at least two of them, it's time to visit a service center.
- Fan noise during everyday tasks like browsing, email, or Zoom calls. Normal operation should be quiet
- CPU temperature reaching 90–100°C under load (check via Activity Monitor or iStat Menus)
- CPU throttling – the MacBook starts lagging during tasks that used to run smoothly
- Hot case around the keyboard and trackpad area even when idle
- Increased battery drain – the fans consume additional power when running at high speed
You can check CPU load through the built-in Activity Monitor app. If the processor is consistently loaded above 80% by kernel processes, it could also be a software issue rather than just dust.
What tools and materials we use
Cleaning a MacBook is not just "blowing it with a vacuum." We use professional equipment to ensure component safety and quality results.
- Anti-static brushes and wipes to prevent component damage from static electricity
- Isopropyl alcohol (99.9%) for cleaning contacts and old thermal paste residue
- Compressed air for blowing out hard-to-reach areas of the heatsink
- Plastic spudgers for disconnecting flex cables without damaging connectors
- Professional Pentalobe and Torx screwdrivers – the standard for Apple devices
Thermal paste replacement
Thermal paste is a heat-conducting compound between the processor and the heatsink. Over time it dries out and loses its properties, leading to a temperature increase of 15–25°C. Thermal paste replacement is an essential part of a complete cleaning.
We use Arctic MX-4 and Thermal Grizzly Kryonaut – proven compounds with high thermal conductivity and long lifespan (3–5 years). We recommend replacing thermal paste every 2–3 years, even if there are no visible problems.
After replacing the thermal paste, we run a stress test under load and record the temperature before and after. A typical reduction is 15–20°C. We show the results to the client.
