Many users are faced with a situation where the device suddenly begins to make noise and the screen dims due to overheating protection. Heatsink is a critical factor for the long life of any modern computing machine. If you notice that your laptop became hot even during simple tasks, which means the cooling system is working at its limit.
Ignoring the problem can lead to thermal paste degradation and failure of the processor or video card. In this article we will look at what physical means can be used to improve air circulation and what materials are absolutely not suitable for these purposes. Proper organization of the space under the housing can reduce the temperature by several degrees without additional costs.
Why overheating becomes fatal for equipment
Modern components processor and video card generate enormous amounts of heat under load. Manufacturers include a certain reserve in the design of the cooling system, but it is quickly depleted if the air flow is disrupted. Most models Asus, Lenovo and HP take air from below through ventilation grilles.
When the laptop is placed on a soft surface such as a blanket or sofa, the holes become blocked. This creates the effect of a thermos, where hot air cannot escape and cold air cannot enter. As a result, the temperature of the components increases exponentially.
High temperatures cause throttling — a mechanism for forced frequency reduction to protect the chip. Your system starts to work slower, lags appear in games and when working with graphics. Ignoring this signal may result in permanent damage to the solder joints on the board.
⚠️ Warning: Continuous operation at temperatures above 90°C may shorten battery life and cause battery swelling.
Specialized stands and coolers
The most obvious solution is to buy a ready-made accessory. The market offers many options for stands with active and passive cooling. Active models are equipped with built-in fans that force air inside the case. Passive ones simply lift the device, creating a gap for natural convection.
When choosing a model, pay attention to compatibility with your size. MacBook or gaming laptop. It is important that the ventilation holes on the stand line up with the holes on the bottom of the device. Otherwise, the efficiency will be close to zero.
- 🌪️ Active stands with adjustable fan speed
- 📐 Perforated aluminum stands for passive cooling
- 🔧 Folding models with the ability to change the angle of inclination for ergonomics
Some models have built-in lighting or USB hubs, which adds functionality. However, remember that excess electronic components may themselves become hot and require power.

Homemade Emergency Cooling Materials
If you don’t have a special stand at hand, you can use improvised means. The main rule is that the material must be hard and have minimal thermal conductivity so as not to heat up from the body. An ordinary book or a thick box can be a temporary solution.
Solid file folders or wooden cutting boards work great. They create the necessary gap and do not absorb heat. It is important that the surface is level, otherwise the laptop may tip over when you press the keyboard.
Avoid using soft materials such as pillows or blankets, even if they appear smooth. Micropores in the fabric quickly become clogged with dust and block air access. Air gap must be clean and free.
⚠️ Caution: Do not use metal objects without insulation as they may cause a short circuit if they accidentally come into contact with internal components through the ventilation holes.
Materials that should absolutely not be used
There are a number of materials the use of which is not only useless, but also dangerous. These include any types of textiles, fur, duvets and soft rugs. They instantly block the ventilation ducts, turning the laptop into an oven.
It is also not recommended to place the device on glass or plastic if they have a smooth surface without texture. Slipping may result in a fall. In addition, some types of plastic release harmful substances when heated and become deformed.
- 🚫 Soft fabrics and bedding
- 🚫 Deep shag carpets
- 🚫 Paper and newspapers (may catch fire at critical temperatures)
It is especially dangerous to use cardboard if it is too thin. It may bend under the weight of the device, again blocking the air supply. Hardness and shape stability are the main selection criteria.
Comparison table of materials and their effectiveness
For clarity, let's compare different materials based on their ability to remove heat and create a gap. Data based on temperature drop tests at maximum load.
| Material | Creating a Gap | Thermal conductivity | Cooling efficiency |
|---|---|---|---|
| Aluminum stand | High | High (dissipates heat) | ⭐⭐⭐⭐⭐ |
| Wooden board | Medium | Low (isolates) | ⭐⭐⭐⭐ |
| Plastic folder | Low | Average | ⭐⭐⭐ |
| Blanket | Zero | Low (getting warm) | ❌ Dangerous |
| Glass | Medium | High (accumulates) | ⭐⭐ |
As can be seen from the table, metal structures work best, since they not only create a gap, but also remove heat from the body themselves. Wood is an excellent insulator, preventing the table surface from heating up.
Additional measures to improve ventilation
In addition to placing items underneath, the cooling system needs to be serviced regularly. Dust accumulation in heat sinks and fan blades reduces efficiency even when the laptop is positioned in an ideal position. Cleaning should be carried out at least once every six months.
Use a can of compressed air to blow out the vents. Do this with short presses to prevent condensation from getting inside. If you are not confident in your abilities, it is better to contact a service center.
☑️ Preparing to clean the cooling system
It is also worth checking the condition of the thermal interface. Over time, thermal paste dries out and loses its properties. Replacement with high-quality paste, for example, from brands Arctic or Noctua, can reduce the temperature by 5-10 degrees.
What tools are needed to replace thermal paste?
You will need a screwdriver (usually a Phillips head), new thermal paste, isopropyl alcohol, and a lint-free cloth. Be careful with the screws so as not to strip the threads.
Ergonomics and safety when using stands
Raising your laptop to cool it also solves an ergonomic problem. The keyboard is at eye level, which reduces strain on the neck. However, it is important to ensure the structure is stable so that the device does not fall while printing.
Make sure that the stand does not block the ports for connecting a mouse or flash drive. If active cooling is used, check the length of the power cable and the ability to connect to the laptop's USB port.
- 🛡️ Use non-slip pads for stability
- 🔌 Do not bend the power cables of the stand
- 📏 Watch your angle to avoid straining your wrists
Proper organization of the workplace is not only comfort, but also a guarantee that your laptop will last for many years without failure. Ignoring a simple gap under the case could cost you more in repairs than the cost of the stand itself.
Using a hard, perforated surface under your laptop is the easiest and cheapest way to extend the life of the device and maintain high performance.
Frequently asked questions (FAQ)
Is it possible to place a laptop on ice for quick cooling?
No, this is strictly prohibited. A sudden change in temperature will cause condensation to form inside the case, which will lead to a short circuit and failure of the electronics.
Do I need to add a stand if the laptop does not heat up?
If the laptop is running in idle mode and the temperature is normal, a stand is not necessary. However, for gaming or video rendering it is highly desirable to prevent overheating.
How often should fans be cleaned?
It is recommended to carry out preventative cleaning once every 6 months. If the laptop is operated in a dusty environment, the interval should be reduced to 3 months.
Does the color of the stand affect cooling?
The impact is minimal. Dark colors absorb heat better, but the material and perforation are more important for the stand than the color.
Can I use a plastic cutting board?
Technically it is possible, since it is solid. But make sure it's clean and doesn't have any deep grooves that could interfere with the laptop's stability.
