How to Fix Laptop Fan Noise

A noisy laptop fan is annoying and often signals a bigger problem — overheating. Ignoring it can lead to CPU throttling, data loss, or permanent hardware damage.

Types of Fan Noise

Whirring (constant high speed): Fan is working overtime because vents are blocked or thermal paste is dried out.
Grinding/Rattling: Fan bearing is failing — replacement needed soon.
Clicking: Fan blade hitting something — could be debris or a warped blade.

DIY Cleaning

1. Power off and unplug 2. Open back panel (check YouTube for your model) 3. Use compressed air to blow out dust from vents and fan blades 4. Hold fan in place while blowing (don't let it free-spin) 5. Clean dust between heatsink fins

Thermal Paste Reapplication

If cleaning doesn't help, dried thermal paste between CPU/GPU and heatsink reduces heat transfer. Reapplying quality thermal paste (Arctic MX-6, Noctua NT-H2) can drop temperatures by 10–20°C.

Fan Replacement

At Xigox, fan cleaning starts at ₹499 and fan replacement at ₹799–₹1,999. We also reapply thermal paste during every fan service. Turnaround: same day.
