Bottom too hot to touch, fan constantly roaring, laptop shutting down out of nowhere? Chennai's heat makes this worse — and it's the #1 cause of motherboard damage.
Overheating rarely fixes itself. Left unattended, it stresses the motherboard and can lead to permanent chip-level damage — a cleaning service now is far more cost-effective than a repair later.
Free basic diagnosis. Testing charges may apply for deep analysis. You approve the cost before we touch anything.
Any of these on a regular basis means it's time for a cleaning and thermal service.
Understanding the likely cause helps you decide whether it's a quick fix or something that needs a technician.
The most common cause in Chennai — dust builds up over months and blocks airflow almost completely.
The paste between the CPU/GPU and heatsink dries out over 2-3 years, reducing heat transfer significantly.
Using the laptop on a bed, pillow, or lap blocks the bottom vents entirely, trapping heat inside.
A fan that's slowing down, noisy, or has worn bearings can't move enough air to cool the system properly.
Try these first — they're safe, take a few minutes, and sometimes solve the problem without a repair visit.
Beds and pillows are the single biggest cause of blocked vents — this alone can help significantly.
Look at the exhaust vent (usually side or back) for visible dust buildup.
Fewer running programs means less heat generated in the first place.
If it's shut off from overheating, give it 15-20 minutes to cool before switching back on.
If you smell burning, see any discolouration near the vents, or the shutdowns are becoming frequent, stop using the laptop and bring it in — continued use risks permanent motherboard damage.
We open the unit fully — not just blow air through vents — to clear dust from the fan, heatsink, and board.
Quality thermal paste reapplied to restore proper heat transfer from CPU/GPU to the heatsink.
We test fan speed and bearing condition, replacing it if it's on its way out.
We measure temperatures before and after so you can see the actual improvement.
We fix overheating issues on all major laptop brands serviced in Chennai.
We measure current idle and load temperatures to confirm overheating.
Fan, heatsink, and vents cleaned thoroughly — not just a surface blow-out.
Old, dried paste replaced with fresh, quality thermal compound.
Laptop run under load again to confirm temperatures have dropped to a safe range.
Given the dust and humidity here, we recommend a cleaning service every 6-8 months for regularly used laptops.
Yes — prolonged overheating is the leading cause of motherboard and chip-level failures. Addressing it early is far more cost-effective than a board repair later.
Yes, especially on laptops 2+ years old. Dried thermal paste is one of the most common causes of overheating we see, even in otherwise well-maintained laptops.
In most cases, yes. If the fan itself has failed, it will need replacement — we'll confirm this during diagnosis.
We'd recommend against it — it blocks the bottom vents almost completely and is one of the top causes of overheating we see.
A full cleaning and thermal paste service is usually completed within a few hours, same-day.
