Laptop Overheating, Throttling & Cooling Fan Repair
Loud fans, hot chassis, throttling or sudden shutdowns — full teardown, ultrasonic heatsink clean, premium compound and before-and-after temperature proof.
Overheating is the most under-treated laptop problem in this region and the one that causes the most expensive damage later. The chain is straightforward: dust blocks the heatsink fins, airflow drops, temperatures climb, the processor throttles itself to avoid damage, and the machine feels slow. If it continues for long enough, sustained heat cracks the solder joints under the GPU or chipset — and at that point you are looking at a reball, not a clean.
The honest good news is that the fix at the early stage is cheap. A full teardown, ultrasonic cleaning of the heatsink fins, premium thermal compound and correctly specified thermal pads typically drops peak temperatures by 15–25°C on a neglected machine. We measure before and after and give you the graphs, so you can see exactly what you paid for rather than taking our word for it.
The technical detail, if you want it
There are three separate things that go wrong in a laptop cooling system, and a proper service addresses all of them.
First, the heatsink fins. Air is pulled in through the bottom vents and pushed out through the fins by the fan. Over time a dense mat of dust and lint forms against the fins, and because it sits on the exhaust side you cannot see it or blow it out from outside. Compressed air through the vents pushes it deeper. It has to be removed physically with the heatsink off — which is why 'blowing the fan out' is not a service.
Second, the thermal interface. The compound between the processor die and the heatsink dries out over three to five years and stops transferring heat. Replacing it is essential, but so is quantity and quality — too much compound insulates rather than conducts. Alongside it, the thermal pads on the VRM, memory and graphics power stages compress and harden, and they must be replaced at the correct thickness. A pad that is too thin leaves an air gap; too thick and it holds the heatsink off the die.
Third, the fan itself. Sleeve bearings dry out and the fan starts rattling or whining, and airflow drops well before it fails completely. A fan that has begun making noise is already moving less air than it should.
On top of all that, we check the fan curve. Many manufacturers set conservative curves that let the machine run hot before ramping the fan. Where the model allows it, adjusting that is free and makes a real difference.
How we carry out this repair
Every stage is documented and you see photographs of the actual fault before you approve any work.
-
Step 01
Baseline temperature measurement
We record idle and full-load CPU and GPU temperatures, fan speed and clock throttling before touching anything. This becomes the "before" half of your report.
-
Step 02
Full teardown
Bottom panel, board and heatsink assembly removed. This is the only way to reach the dust mat on the exhaust side of the fins — compressed air from outside pushes it deeper.
-
Step 03
Ultrasonic heatsink cleaning
The heatsink and fan are cleaned ultrasonically so the fins are genuinely clear, then dried thoroughly before reassembly.
-
Step 04
Fan inspection and lubrication
Bearing checked for wear and play. Serviceable fans are cleaned and lubricated; worn ones are quoted for replacement with the reason explained.
-
Step 05
Premium compound and correct pads
High-conductivity thermal compound applied in the right quantity, and thermal pads replaced at the correct thickness on the VRM, memory and graphics power stages.
-
Step 06
Vent and intake clearing
Bottom intake grilles and exhaust vents cleared, and internal dust filters cleaned or replaced where the model has them.
-
Step 07
Load testing and proof
A one-hour stress test on CPU and GPU together, with the after-temperatures recorded and both graphs shared with you.
-
Step 08
Fan curve tuning
Where the model permits it, we set a more sensible fan curve so the cooling responds before the machine is already hot. No extra charge.
Options and prices
Where more than one approach solves your fault, we quote all of them and explain the trade-off. The cheapest option that genuinely works is always on the list.
| Option | Price | Notes |
|---|---|---|
| Full cooling service (clean + compound + pads) Our standard service. Typically drops peak temperatures 15–25°C. | ₹800 – ₹1,600 | Our standard service. Typically drops peak temperatures 15–25°C. |
| Cooling fan replacement Where the bearing is worn beyond servicing. | ₹1,200 – ₹2,600 | Where the bearing is worn beyond servicing. |
| Gaming laptop dual-fan service Both fans, full pad replacement, liquid metal available on request. | ₹1,600 – ₹2,800 | Both fans, full pad replacement, liquid metal available on request. |
| Heatsink replacement (bent or damaged pipes) Where a heat pipe has been crushed or has lost its working fluid. | ₹2,200 – ₹3,800 | Where a heat pipe has been crushed or has lost its working fluid. |
| Annual maintenance plan Two scheduled services a year — the recommended cycle in this region. | ₹1,400 per year | Two scheduled services a year — the recommended cycle in this region. |
| Thermal health check only Measured under load, with the report, whether or not you proceed. | Free | Measured under load, with the report, whether or not you proceed. |
Prices are indicative ranges. Your exact figure is confirmed in writing after the ₹350 bench diagnosis, and it does not change afterwards.
Advice from our bench
Some of this reduces the amount of work we get. We would still rather you knew it.
Never use a laptop on a bed, sofa or cushion. It seals the bottom intake vents completely and is the single most common cause of overheating we see.
A simple stand that lifts the rear by two centimetres improves airflow noticeably and costs almost nothing.
Do not blow compressed air into the vents. It pushes the dust mat deeper into the fins where it becomes harder to remove.
In this region, service every six months rather than annually — dust and heat levels here are well above average.
A fan that has started making noise is already moving less air. That is the cheap moment to act, not after the shutdowns start.

Customers who had this repair
“My Omen was shutting down mid-game and two shops told me the graphics card had failed. These guys measured the temperatures first, showed me the graph, and it turned out the heatsink was completely blocked. Full clean and repaste, temperatures dropped by around 20 degrees, and it has been stable for four months. They saved me from buying a card I did not need.”

“The service centre quoted me ₹16,500 for a new motherboard. I brought that quote here and they opened it under a microscope, photographed the burnt component and repaired it for ₹2,800. They also showed me why my charger was causing it. Three months on, no problems at all.”

“Our parish office computer stopped working and we were told to buy a new one. They came out, found it was the power supply, replaced it for a small amount and also set up backups for our records which nobody had ever done. Very patient in explaining everything. We now have them on a yearly arrangement.”
