Laptop overheating repair in Montréal
A hot laptop is not always a sign that the fan needs replacement. Dust buildup, blocked airflow, dried thermal compound, a failing fan, heavy background activity or a hardware fault can all produce similar symptoms. Laptop Clinic checks the cooling problem before recommending parts.
Common overheating symptoms
Typical signs include a fan that runs loudly most of the time, a keyboard or bottom case that becomes unusually hot, sudden shutdowns under load, performance that drops after a few minutes, games that begin smoothly and then stutter, or temperatures that rise quickly during normal tasks. Some modern laptops naturally run warm, so the pattern and severity matter more than temperature alone.
Dust can restrict the heatsink and vents, but software load can also keep the processor or graphics chip busy. A useful diagnosis considers temperatures, fan behaviour, airflow, background activity and whether the problem appears only under heavy work or even while the computer is nearly idle.
Cleaning, thermal service or fan repair?
If airflow is restricted, internal cleaning may restore normal cooling. On suitable systems, old thermal compound may also need replacement. A grinding, stalled or electrically faulty fan can require a compatible replacement. These are different repairs, so replacing the fan before checking the cooling path can waste money.
We avoid promising a universal temperature reduction because laptop designs vary. The practical goal is stable operation, normal fan behaviour for the workload, and temperatures that do not cause repeated throttling or shutdowns.
When to stop using an overheating laptop
If the laptop repeatedly shuts off from heat, smells unusual, has a swollen battery, or the fan has stopped while the machine becomes very hot, continued use can increase risk to components. Back up important files when possible and have the system inspected before extended heavy use.

Frequently asked questions
Can dust make a laptop overheat?
Yes. Dust can restrict vents and heatsinks, but temperatures should be checked because software load, a fan fault or another hardware issue can create similar symptoms.
Do you replace thermal paste?
On suitable systems, yes. It is considered when the cooling system is opened and the thermal interface is old, disturbed or part of the diagnosed problem.
Why does my laptop slow down when it gets hot?
Processors and graphics chips can reduce speed to control temperature. This is called thermal throttling and can cause noticeable performance drops.
