Prevent overheating and thus avoid total damage

This measure is usually free of charge – the laptop owner only has to invest some time. This can be worthwhile, especially if the first signs of a necessary notebook fan cleaning are already appearing!

Is your new laptop already giving out after half a year? The notebook is loud or whistling because the fan is constantly spinning up. It is slow, gets very warm, hot or even simply switches off.

Often the reason for this is a dirty fan / heat exchanger. It is contaminated with dust, dirt, hair, cat hair, crumbs or cigarette ash. If the fan is not cleaned regularly, it can lead to heat damage on the motherboard, the graphics card or the graphics chip (GPU), which can be very expensive (often 400 EURO and more for a motherboard repair). This error manifests itself through unstable operation and crashes during longer runtimes.

Save yourself the costs with a simple fan cleaning. In most cases, it is a simple and quick matter and, with regular use, significantly increases the lifespan of the notebook! Ideally, the fan should be cleaned every 6 months.

The cheapest way is to carry out the cleaning of the fan yourself, but caution is advised, as it can lead to loss of warranty depending on the manufacturer (e.g. if screws are missing).

Measures: What needs to be considered?

First, for safety reasons, the power supply must be unplugged and the battery removed. Depending on the model and manufacturer, access to the fan is easy or complicated. With Acer, Lenovo or Fujitsu notebooks, usually only the service flap on the back of the notebook has to be removed to get to the heat sink. In devices from Toshiba, Medion or HP, the fans / coolers are usually blocked and therefore very difficult to access. It may be that the entire notebook has to be disassembled before you can get to the fan.

We advise to completely remove the fan and not just blow over it. Experience has shown that most of the dust settles between the fins of the heat sink and the fan. A so-called dust carpet is not uncommon after some time. Here you must be careful not to bend or break the thin copper fins! The fins are best cleaned with a brush and air pressure. Keep your fingers away from cotton swabs or vacuum cleaners. A small layer of dust on the rotor blades is not bad, don’t take any risks and rather leave it. If the blades break off, a new fan must be purchased.

What needs to be considered when assembling the laptop?

When reassembling the notebook, make sure whether the coolants need to be renewed. If the thermal paste is hardened, for example, it must be renewed urgently so that the heat transfer is guaranteed.

IMPORTANT: Do not forget to plug the fan cable back onto the motherboard, otherwise it will not be long before the notebook suffers overheating damage.

Now your laptop should run whisper-quiet and quietly again.
