I got my HP Omen gaming laptop's thermal paste changed and deep cleaned here. The service was super good and quick, done within an hour! 🚀 They even gave me tips on laptop care. The price was reasonable at 1200Rs, and they use quality thermal paste too. Highly recommend! 👍😊💻 …
Fan never stops · buzzing · rattling · silent while hot
Laptop fan running constantly or making noise
Fans speed up with heat. A fan that is always at full speed is working hard against a blocked heatsink; a fan that rattles has a worn bearing; a fan that is silent while the laptop is hot has stopped. Each has a straightforward fix.
Quick answer
Constant high fan speed at idle means the laptop is hot for no reason: dust in the fins, dried paste, or software running the processor. Buzzing or rattling is a worn bearing and the fan is replaced. Silence while the base is hot means the fan has stopped and the laptop is throttling to survive.
Likely causes
- CommonBlocked heatsink fins
- The fan spins hard but moves little air. Cleaning fixes it. Thermal service
- CommonSoftware keeping the processor busy
- Check Task Manager first; a runaway process makes the fan roar with nothing open.
- SometimesWorn fan bearing
- Buzzing, rattling or a grinding note. The fan is replaced as a unit.
- SometimesFan stopped
- Silent and hot. Replace before the heat does damage.
- RareSomething touching the blades
- A label, a loose screw or a cable. Quick fix once opened.
Safe checks you can do first
- Task Manager → Performance → CPU at idle. Near zero and still loud means airflow; high means software.
- Listen for the type of noise: steady whoosh is airflow, buzz or rattle is the bearing.
- Feel for air at the exhaust. None means blocked or stopped.
- Check when it started: gradual over months (dust) or sudden (bearing or software).
What not to do
- Do not spray compressed air into a closed laptop; it drives dust deeper and can over-spin the fan.
- Do not oil the fan; laptop fans are sealed and it does not last.
- Do not use fan-control software to quieten a fan that is loud for a reason.
When it is a repair, and which one
A thermal service clears the fins and re-pastes; if the bearing is worn or the fan has stopped, we fit a new fan for your model in the same job. Temperatures are logged before and after.

My laptop used to heat up uncontrollably within just 10 minutes of gaming, which severely affected its performance. I consulted Skylab regarding this issue, and they recommended a complete laptop service. Upon inspection, they found that …
Questions people ask
Before you decide
Is it normal for a laptop fan to run constantly?
Under load, yes. At idle on a desk, no. Constant noise at idle means blocked cooling or busy software.
Can a laptop fan be repaired or replaced?
Replaced, yes; fans are model-specific parts we source. Repairing a worn bearing is not reliable.
Can a new fan improve performance?
If the old one had slowed or stopped, yes: the processor stops throttling. If the fan was fine and the fins were blocked, cleaning gives the same result.
