MacBook Air Fan & Thermal ServiceJohannesburg & Gauteng
If your MacBook Air sounds ready for takeoff and runs hot enough to toast a sandwich, the cooling system is waving a white flag. (Yes — even the fanless ones throttle.) Dust, dried thermal paste, a worn-out fan: we sort all three and bring the temperature back to earth.

MacBook Air overheating problems we fix
Severe throttling — A1932 / A2179 design flaw
The 2018–2020 MacBook Air has a fundamentally flawed thermal design: the CPU fan is not aimed directly at the processor heatsink. Under any sustained load the Core i5 hits 90–100°C and macOS throttles performance. Thermal paste replacement plus copper shim installation reduces temperatures by 20–30°C and significantly reduces or eliminates throttling.
Fan running at full speed constantly
Fan stuck at maximum speed despite a cool or idle machine usually indicates a failed temperature sensor — most commonly the battery thermistor. The SMC runs the fan at max when it cannot read temperature. Apple Diagnostics error codes PPT006 or PFM006 confirm this. Battery replacement resolves most cases.
Fan grinding or rattling noise
Bearing wear inside the fan causes grinding or clicking at certain RPMs. A failing fan bearing cannot be repaired — fan replacement required. A seized fan leaves the machine with no cooling at all.
Fan not spinning
A fan that doesn't spin causes rapid CPU temperature rise and emergency shutdown. Causes: failed fan motor, broken cable, or board fault on the fan power rail.
MacBook Air hot on palm rest or bottom
Excessive chassis heat on A1466 models is usually dried thermal paste — 5+ year old machines often have paste that has hardened and cracked. Thermal paste replacement restores normal temperatures.
Machine sluggish under any load
The CPU throttle cycle: fan ramps up, CPU cools, macOS releases throttle, CPU heats again, cycle repeats. Machine feels slow and inconsistent. Thermal service breaks this cycle.

MacBook Air fan and thermal service — questions we get asked
My MacBook Air is slow and hot — will thermal service fix it?
On 2018–2020 models yes — the thermal design is genuinely poor and thermal paste replacement plus copper shim makes a measurable real-world difference. On A1466 models with dried paste, the improvement can be dramatic. iAssist measures CPU temperature before and after.
What is a copper shim and why does it help the 2018–2020 MacBook Air?
Apple left a gap between the CPU die and the heatsink on the A1932/A2179. A copper shim fills that gap, creating direct metal-to-metal contact so heat transfers more efficiently. Combined with quality thermal paste this reduces sustained CPU temperature by 20–30°C.
Does thermal paste dry out on older MacBook Airs?
Yes. Factory thermal paste typically hardens and loses effectiveness after 4–6 years. On A1466 models from 2013–2017, most machines are now well overdue for fresh paste.
My fan runs at full speed all the time — what is wrong?
Most likely a failed temperature sensor — the battery thermistor is the most common culprit. Run Apple Diagnostics (restart, hold Option+D) and check for PPT006 or PFM006 error codes. Battery replacement resolves this in most cases.
Is the M1 M2 M3 MacBook Air fanless?
Yes. All Apple Silicon MacBook Airs (M1 through M5) have no fan whatsoever. They use passive cooling only. No fan service is possible or required — they are completely silent by design.
How much does MacBook Air thermal service cost?
Thermal paste from R900. Full thermal service for A1932/A2179 (paste and shim) R1,400. Fan replacement from R1,400. Free diagnostic before quoting.
Will thermal service void my warranty?
Opening the MacBook Air for thermal service does not void AppleCare on other components. iAssist provides a 6-month warranty on all thermal work.
How long does thermal service take?
Thermal paste and copper shim installation is same-day. Fan replacement is same-day if we have stock, or next-day if we need to order.
My fan is making a grinding noise — is it urgent?
Yes. A failing fan bearing can seize, leaving the machine with no cooling at all. If the grinding gets worse, bring it in soon. A seized fan leads to CPU damage from sustained heat.
Can you measure the improvement after the service?
Yes — iAssist records CPU temperature under sustained load before and after so you can see the actual improvement.
