💨 DIY Guide: Cleaning Your Notebook's Cooler

🛠️ How to clean your laptop's fans and heatsinks

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.

🧽 Step-by-step guide to cleaning the system

1. 🔧 Disassemble the laptop and remove the motherboard to access the system.
2. 💨 Separate the heatsink and fan, removing any thermal pads.
3. 🖤 Limpia toda la suciedad con aire comprimido.
4. 🧴 Remove the old thermal paste from the processor, graphics card, and chipset.
5. 🌀 Clean the fan blades and grease the shaft.
6. 🟦 Install new thermal pads if applicable.
7. ⚪ Apply quality thermal paste in the right amount.
8. 🔩 Reassemble the fan and heatsink.
9. 🖥️ 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.
