Cleaning the notebook cooler

Complete Guide to Cleaning Your Notebook Cooler – Fans and Heatsinks.

When turning on a notebook and allow electricity to flow through the motherboard, some components begin to warm up.

Two elements in particular get much hotter than the rest: the processor and the graphics chip.

The motherboard of your notebook optimizes its performance when reading the temperature and adjust the speed of the fan (cooler), which is responsible for keeping these components cool.

Operation of the system ventilation from a notebook:

On the one hand, we have the processor (1) and the graphic card with his dedicated memory (2). The heatsink (3) is a key piece of copper that contains a gas inside. It is located above the processor and the graphics card, using a thermal paste to improve heat transfer. The heatsink ends in a few grids (5) which increase their contact surface with the air.

When the motherboard detects that more cooling is needed, it sends more voltage to the fan (Cooler)(4) to make it spin faster. The fan blows the generated air against the heatsink (3) and this air comes out through the grilles (5), which helps keep a stable temperature of both the processor and the graphics chip.

Notebook cooler cleaning – Symptoms of a laptop that needs a complete internal cleaning.

The air entering your notebook, even if you don't notice it, is full of small particles of dust and other impurities. Over time, this causes the system to become dirty and covered with a layer of dirt. This can make it difficult for the notebook maintain the proper temperature.

The symptoms of a notebook with dirty ventilation and dissipation system are:

• • He fan sounds louder. The speed is automatically adjusted, and when it cannot work properly, the 100% is put to work.
  • He keyboard it gets hotterThe heat expands and affects the entire upper area.
  • By placing your hand where the air comes out, you will notice that There is virtually no airflow.
  • He notebook crashes frequently, especially after being on for a while.
  • A occurs general warming up of portable.

Consequences and problems of having a dirty ventilation and dissipation system:

If you detect that your notebook heats up more than usual, it turns off by itself or the fan makes a lot of noise, it is essential that a technical service professional Check the entire ventilation system. Doing so will prevent major problems such as motherboard failure, graphic card or even, due to constant crashes, the operating system may be damaged.

Another component of a laptop that is not given much attention, but which suffers from temperature, is the hard disk. All the heat that cannot escape from the laptop stays inside, heating up all the components and shortening its useful life.

Anything that may happen to you notebook computer will have much higher economic costs than the ventilation system cleaning service.

How do we clean? How to clean?

• The first thing is to disassemble the notebook and remove the motherboard. It is the only way to access the ventilation and dissipation system.
• Separate the heatsink and fan from the motherboard. Remove any thermal pads.
• To physically remove all accumulated dirt, we can use compressed air.
• We remove the old thermal paste with the help of flux remover on the processor, graphics card and chipset.
• We carry out a complete cleaning of the fan blades and its shaft, using compressed air.
• We grease the axle to facilitate its rotation and avoid noise.
• We put in new thermal pads if the laptop had them from the factory.
• We added silver polymer thermal paste to improve dissipation in the correct amount. Very important: The thermal paste has to be of quality and the right amount must be added.
• We mount the fan and heatsink to the motherboard.
• We perform stress tests (put the processor and graphics card to work at maximum) to check that the temperature of the computer is within the correct parameters.

When we deliver a computer portable, which we have carried out a complete cleaning, the client immediately notices that the fan is barely audible and notices much less temperature even with heavy workloads.

How to clean? – It should not be done

To carry out the cleaning the ventilation system, dirt must be removed and not put it in inside. Cleaning should never be done from the outside with an air gun or similar, because what we do is move the dirt directly to the fan and this will return it to the radiator. By pushing the dirt we can create a kind of ball of dirt that prevents the fan from turning and permanently damages it. By pushing from the outside with pressurized air, we can damage the fan blades.
