A laptop that overheats does not just get hot — it throttles performance (slowing down to reduce heat), shuts down unexpectedly, and risks permanent CPU, GPU, and motherboard damage over time. Overheating is one of the most common laptop problems in Mumbai, where the hot climate combined with AC-deprived environments accelerates the problem. Xigox provides same-day doorstep overheating repair across Mumbai.
What Causes a Laptop to Overheat?
- Dried thermal paste — the most common cause. Thermal paste between the CPU/GPU and heat sink dries out after 2–4 years, dramatically reducing heat transfer. A thermal repaste restores full cooling performance.
- Clogged fan and heat sink — dust accumulates in the fan blades and heat sink fins, blocking airflow. This is especially common in Mumbai's dusty environments.
- Failed or degraded fan — fan bearings wear out over time, causing the fan to spin slower or stop entirely.
- Blocked vents — using a laptop on a bed, pillow, or lap blocks the bottom air intake vents, causing immediate temperature spikes.
- High ambient temperature — in summer months, room temperature in non-AC environments can push laptops past their thermal limit.
- Heavy workload — gaming, video editing, or compiling for hours generates sustained heat that an aging cooling system cannot manage.
How Do You Know If Your Laptop Is Overheating?
- Bottom of laptop is very hot to the touch
- Fan runs at maximum speed constantly or makes grinding/rattling noise
- Performance drops suddenly during heavy tasks (thermal throttling)
- Laptop shuts down without warning during use
- Blue screen errors under load (BSOD)
- CPU/GPU temperature above 95°C shown in monitoring software
What Overheating Repairs Does Xigox Provide?
- Thermal repaste — remove old thermal paste, clean CPU and GPU die and heat sink, apply high-quality thermal compound (Thermal Grizzly or equivalent)
- Fan and heat sink clean — full disassembly, compressed air and brush clean of fan blades and heat sink fins
- Fan replacement — if fan is worn, slow, or making noise; OEM-spec replacement fans sourced per model
- Heat sink replacement — if heat sink is bent, corroded, or has damaged contact pads
- Thermal pad replacement — VRAM and other chips use thermal pads; replace if degraded
- Liquid metal application — for Razer Blade and ASUS ROG Zephyrus that use liquid metal from factory; requires specialist handling

Will a Thermal Repaste Actually Make My Laptop Faster?
Yes — significantly, if thermal throttling was occurring. Thermal throttling automatically reduces CPU and GPU clock speeds to prevent overheating damage. A laptop running at 95–100°C may be running at 40–60% of its designed performance. After a proper thermal repaste and fan clean, temperatures typically drop 15–30°C under load, and the CPU and GPU run at full rated speed. Users consistently report faster rendering, smoother gaming, and quicker compilation after overheating repair.
How Long Does Overheating Repair Last?
A quality thermal repaste with premium compound lasts 2–4 years before needing to be redone. Annual fan cleaning (without repaste) is recommended for heavy users. Gaming laptops benefit from a repaste every 18 months due to the sustained high temperatures they generate. We include a free 6-month thermal health check reminder with every overheating repair at Xigox.
