Quick answer: Fixing an overheating laptop in Delhi costs ₹699–₹1,499 for a full fan clean plus fresh thermal paste and pads, or ₹999–₹2,499 if the fan itself has to be replaced (part included). Both are same-day jobs at CNC, West Patel Nagar, and can be done at your doorstep within 10 km for a ₹299 visit charge adjusted against the repair. Free diagnosis. No Fix No Charge.
Is your laptop actually overheating? 6 symptoms
- Fan runs loudly all the time, or has gone completely silent
- Bottom panel or keyboard too hot to keep on your lap
- Sudden shutdowns or restarts during video calls, gaming, or Tally/Excel work
- Performance drops after 10–15 minutes (thermal throttling — CPU slows itself to survive)
- “Fan error” or “thermal event” message at boot (common on Lenovo ThinkPad and Dell)
- Laptop is 2+ years old and has never been opened for cleaning — Delhi dust guarantees a clogged heatsink

Why “just cleaning” is often not enough
Thermal paste dries out in 2–3 years in Delhi’s heat. Blowing compressed air through the vents removes dust from the fan but leaves the hardened paste — temperatures drop 3–5 °C instead of 15–25 °C. A proper job means removing the heatsink, cleaning old paste with isopropyl alcohol, applying fresh paste and replacing the thermal pads on VRMs and the GPU. Ask your repair shop whether they’re opening the heatsink; if not, you’re paying for half a fix.
Can you prevent it?
- Use the laptop on a hard surface — beds and sofas block the intake
- A ₹500–₹800 cooling pad helps gaming laptops; it does not fix bad paste
- Clean + repaste every 2 years; every year if the laptop lives in a dusty office or near a road
- Keep BIOS updated — Dell and HP have released fan-curve fixes for several models

FAQs
How long does fan cleaning and repasting take?
1–2 hours for most laptops; 2–3 hours for gaming or dual-fan models. You can wait or we’ll message you when it’s ready.
Will opening the laptop void my warranty?
If it’s under brand warranty, take it to the brand first — overheating on a new laptop is usually a manufacturing fault. Out of warranty, opening it has no downside.
Is thermal paste replacement worth it on a 5-year-old laptop?
Yes — it’s the single cheapest upgrade that noticeably improves speed on an old laptop, alongside an SSD (from ₹499 labour + part).
Do you do doorstep fan cleaning in Delhi?
Yes within 10 km of West Patel Nagar (Rajouri Garden, Karol Bagh, Paschim Vihar, Janakpuri, Punjabi Bagh, Moti Nagar, Kirti Nagar, Rajendra Place, Pitampura) for a ₹299 visit charge adjusted against the repair.
