Fan silent, grinding, or spinning non-stop?

A fan that won't spin at all is more urgent than one that's just loud — without airflow, internal components can overheat quickly.

★★★★★

The fan of my 27” iMac has stopped working. I googled and found Dotronix. Mr Arshard served me and he did a very good job, especially in keeping me updated throughout the repair period. He was also able to fulfill my request to get everything done within a day as I needed to use my computer urgently. Dotronix has also done a thorough dusting of my iMac’s internal components as well as refreshed the thermal paste for its CPU for better cooling. Overall highly recommended 5/5 for their service and reasonable fees.

The screen of my laptop was flickering and it got LCD replaced with reasonable price… seeking the Sifu to inspect the internal motherboard and notice the thermal paste has long gone due to aged… can refer to the attached photo for before, cleaning, and after thermal paste applied… can’t wait to get my laptop back 😇 thumbs up for the service and less hassle for sending or collecting

What's going on

The fan motor itself can fail from age, dust build-up seizing the bearings, or a damaged connector cutting power to it. If your MacBook feels unusually hot but you don't hear the fan working at all, that's a more urgent situation than a fan that's simply loud — the system loses its ability to cool itself. We diagnose whether it's the motor, the connector, or the logic board's fan control circuit.

Common signs to look out for

No fan noise at all, even under heavy load
A grinding, rattling or clicking noise from the fan
Fan runs constantly at full speed, even when idle
Unusually hot chassis with silent fan operation
A burning or electrical smell near the vents

What usually causes it

A seized or worn-out fan motor bearing
Dust and debris obstructing the fan blades
A damaged fan connector or cable
A logic board fault affecting fan control

How we diagnose this

Fan noise & spin diagnostic

We isolate whether the fault is the motor, the connector, or fan control itself.

Bearing & blade inspection

We check for seizure or obstruction in the fan motor and blades.

Repair or replace

Depending on the fault, that's a connector fix or a full fan unit replacement.

Airflow & thermal retest

We confirm normal fan operation and airflow before the MacBook is handed back.

Common questions

MacBook fan repair FAQs

My MacBook feels hot but I can't hear the fan — is that serious?

Yes, more urgent than a fan that's simply loud. A silent fan under load means the system has lost its ability to cool itself, which can lead to overheating damage if left unaddressed.

How much does MacBook fan repair cost?

Fan repair or replacement starts from RM 250. The exact cost depends on whether it's a connector fix or a full fan unit replacement, confirmed after diagnosis.

How long does fan repair take?

Typically 1 to 2 days, depending on part availability for your exact model.

Is same-day service available for fan repair / replacement, or is 1–2 days the norm?

Same-day is common when the part is in stock and the fault is straightforward — the 1–2 days window mainly accounts for part availability for less common MacBook models. We confirm your actual timeline after diagnosis, not just the general range.

Does this repair put my files or data at risk?

No. This is a hardware-level fix that doesn't touch your storage or files — your MacBook boots back into exactly the same software state it was in before, data untouched.

What warranty applies to this repair?

Every repair carries our Standard Component Warranty, terms and conditions applying to labour and the fix itself. If a replacement part carries its own separate manufacturer or supplier warranty — batteries and SSDs typically do — that can extend further depending on the specific part, and we tell you exactly what applies to your repair before any work begins.

Do I have to pay a diagnostic fee if I decide not to go ahead?

No. Basic live-agent assessment is always free at Dotronix, whether you approve the repair afterward or not. You only pay if you say yes to the quote we send you.

Do I need to visit in person, or can it be picked up — for fan repair / replacement?

Both work, shaped to each hub. Book ahead with Our Live Agent for a guided workshop visit in Kepong, or visit our Kuchai Lama branch — call/WhatsApp first to confirm availability. Either way you get the same diagnosis and pricing.
