When turning on a notebook, some components like the processor and the graphics chip 🔥 They generate a lot of heat.
To avoid overheating, the fan (cooler) regulates its speed and dissipates heat through the heatsink and its grids.
🔍 Basic operation of the ventilation system:
📌 Key components
1️⃣ Processor and 2️⃣ graphic card.
3️⃣ Heatsink copper with internal gas and thermal paste.
4️⃣ Fan which pushes air towards the heatsink.
5️⃣ Grilles to expel hot air.
⚠️ Symptoms that your notebook needs internal cleaning
🔊 Fan sounds louder than usual.
🔥 Warm touch keyboard.
💨 Little or no airflow through the outlet.
⛔ Frequent crashes after a while of use.
🌡️ General laptop warm-up.
🚨 Risks of not cleaning in time
A dirty ventilation system can cause:
💥 Motherboard failure.
🎮 Damage to the graphics card.
💾 Shorten the lifespan of the hard drive and other components.
💡 Useful information: Excessive temperature is the most common cause of failures in notebooks, especially in the graphics chip.
🧽 Step-by-step guide to cleaning the system
🔧 Disassemble the laptop and remove the motherboard to access the system.
💨 Separate the heatsink and fan, removing any thermal pads.
🖤 Clean all dirt with compressed air.
🧴 Remove the old thermal paste from the processor, graphics card, and chipset.
🌀 Clean the fan blades and grease the shaft.
🟦 Install new thermal pads if applicable.
⚪ Apply quality thermal paste in the right amount.
🔩 Reassemble the fan and heatsink.
🖥️ Take a stress test to verify correct temperatures.
🚫 What you should NOT do
Do not use compressed air from outside without disassembling it, as this will push dust inside, potentially damaging or blocking the fan.
✅ Expected result
After a thorough cleaning, the fan will be much quieter and temperatures will drop even during demanding tasks.
