Laptops are becoming more powerful, but their compact bodies often fail to cope with heat dissipation. Overheating leads to throttling (automatic performance degradation), sudden shutdowns and even component damage. If your ASUS ROG, Lenovo Legion or budget Acer Aspire reaches 90°C when gaming or rendering, it's time to take action.

This article contains proven ways to improve cooling, from basic (cleaning and thermal paste) to advanced (modding and replacing the cooler). We will look at what you can do yourself, and when it is better to contact the service. Cooling 15–20°C lower within an hour after proper cleaning is a real result at minimal cost.

1. Diagnostics: how to understand that the laptop is overheating

Before improving cooling, you need to confirm the problem. Symptoms of overheating are often confused with viruses or battery problems. Here are the key signs:

  • 🔥Laptop turns off spontaneously during load (games, video conversion).
  • 🐢 Performance drops: FPS in games sags, video slows down, although the CPU/GPU load is not 100%.
  • 💨 The cooler works at maximum even during simple tasks (for example, in Google Chrome with 5 tabs).
  • 🌡️ The case in the area of the keyboard or below becomes hot to the touch (above 50°C).

For accurate diagnosis, use monitoring programs:

  • 📊 HWMonitor - Shows CPU, GPU temperatures, voltage and fan speed.
  • 🎮 MSI Afterburner — convenient for gamers (displays FPS and temperature in the game).
  • 🖥️ Core Temp — specializes in the temperature of processor cores.

Normal temperatures under load:

  • CPU (Intel Core i7/i9, AMD Ryzen 7/9): up to 85–90°C (short-term), optimally - up to 75°C.
  • Video card (NVIDIA RTX 30/40, AMD Radeon RX 6000): up to 80–85°C.

If the values are higher, it’s time to act.

📊 How often do you clean your laptop cooling system?
  • Once every 3–6 months
  • Once a year
  • Only when it starts to warm up
  • Never

2. Cleaning your laptop from dust: step-by-step instructions

Dust is the main enemy of cooling. It clogs radiators, reduces heat transfer and impairs fan performance. Cleaning needs to be done every 6 months (or more often if the laptop is used in a dusty room).

What you will need:

  • 🧹Spray can compressed air (For example, WD-40 Specialist).
  • 🔧 Screwdriver (usually Phillips #0 or T5 for laptops).
  • 🧴 Isopropyl alcohol (70%+) and cotton swabs for cleaning cooler blades.
  • 🛠️ Plastic spatula for neatly opening the case.

Turn off the laptop and disconnect the battery (if it is removable)|

Take pictures of screw locations before disassembly|

Work on an antistatic mat or ground yourself|

Do not blow air into the vents at an angle - this may damage the blades-->

Step by step process:

  1. Unplug your laptop, remove the battery (if possible) and turn it over.
  2. Unscrew the screws on the bottom cover (usually they are marked with a 🔧). Be careful - some models (MacBook Pro, Dell XPS) have hidden latches.
  3. Remove the cover and find the cooling system (radiator + cooler). In budget laptops it can be covered with a metal plate.
  4. Use short bursts (not a continuous stream!) to blow out the radiator with compressed air. Keep the can upright to prevent liquid from escaping.
  5. Soak a cotton swab in isopropyl alcohol and remove any accumulated dust from the fan blades.
  6. Check the thermal paste on the processor and GPU chip - if it is dry or leaking, it needs to be replaced (more on this in the next section).
⚠️ Attention: Do not use a vacuum cleaner to clean your laptop! Static electricity can damage the motherboard. Also avoid metal objects - they can short-circuit the contacts.

3. Replacing thermal paste and thermal pads

Thermal paste transfers heat from the processor to the heatsink. Over time, it dries out and becomes less effective. Replacing thermal paste can reduce the temperature by 5–15°C.

Which thermal paste to choose:

Type Examples Temperature effect Service life
Silicone (budget) Arctic MX-4, DeepCool Z5 Reduction by 3–8°C 2–3 years
Metal (high performance) Thermal Grizzly Kryonaut, Coollaboratory Liquid Ultra Reduction by 8–15°C 1–2 years (requires frequent replacement)
Liquid metal (extreme cooling) Thermal Grizzly Conductonaut Reduction by 10–20°C 5+ years (risk of short circuit!)

How to apply thermal paste:

  1. Remove the old paste with a cloth soaked in isopropyl alcohol. Remove any residue from the processor and heatsink.
  2. Apply a pea-sized drop of paste (≈0.1 ml) to the center of the crystal. For multi-core CPUs (Intel Core i9-13900H, AMD Ryzen 9 7940HS) you can use the "cross" method.
  3. Reinstall the radiator and tighten the screws evenly criss-crossto avoid skew.

Don't forget about thermal pads on VRM chips and GPU memory. They also need to be replaced if they become hard or cracked. Optimal thickness - 1–1.5 mm.

💡

Before applying liquid metal (Conductonaut) Seal the contacts around the processor with Kapton tape - this will prevent a short circuit if it accidentally spreads.

4. Software optimization

Sometimes the laptop gets hot not because of dust, but because of incorrect settings. Here's what you can do without disassembling:

  • 🔄 Update BIOS. Manufacturers often release patches to improve fan control. For example, in Lenovo Legion After updating the BIOS, the coolers began to run quieter at the same temperatures.
  • 🎛️ Set up your power plan. B Control Panel → Power Options select mode "Maximum performance" only when connected to the network. On the battery, use balanced mode.
  • 🚫 Disable unnecessary background processes. B Task Manager check programs that are using CPU (for example, NVIDIA Container, Microsoft Edge in the background).
  • 🎮 Limit FPS in games. With RivaTuner or NVIDIA Reflex, set the limit 1-2 frames below the maximum - this will reduce the load on the GPU.

For advanced users:

  • 🔧 Use ThrottleStop (for Intel) or Ryzen Controller (for AMD) to fine-tune the processor voltage and frequencies. Voltage reduction (undervolting) by 50–100 mV can reduce heat dissipation by 10–15%.
  • 📉 B MSI Afterburner create a custom fan curve. For example, set the cooler speed to 100% at 70°C instead of the standard 85°C.
⚠️ Attention: Undervolting on laptops with processors Intel 12th–13th generation And AMD Ryzen 6000/7000 may lead to instability. Always test the load at Prime95 or FurMark after the changes.

5. Upgrade the cooling system: what can be improved

If cleaning and thermal paste don't help, it's time to consider an upgrade. Here's what you can do:

  • 💨 Cooler replacement. Some laptops (eg. Dell Inspiron, HP Pavilion) fans are removable. You can install a model with a large number of blades or copper bearings (for example, Noctua NF-A12x15).
  • 🔥 Additional heat pipes. In models with one hitpipe (for example, Acer Nitro 5) you can add a second tube for better heat distribution.
  • 🧊 Liquid cooling system. For enthusiasts: some laptops (MSI GT77 Titan, ASUS ROG Zephyrus) you can integrate a custom waterblock, but this requires deep modification.
  • 🛡️ Thermoplates. Replacing standard copper plates with graphite ones (Fujipoly) improves thermal conductivity by 20–30%.

Example of a successful upgrade:

On Lenovo ThinkPad P1 with Intel Core i7-9750H replacing a standard cooler with Noctua NF-A12x25 and adding a second heat pipe reduced the temperature under load from 95°C to 78°C. The cost of modification is ~3,000 ₽.

Where to buy spare parts:

  • 🌍 AliExpress — cheap analogues of coolers and radiators (risk of low quality).
  • 🛒 DNS, Citylink — original spare parts for popular models.
  • 🔧 Specialty stores (for example, Notik.ru) - components for rare laptops.
Is it possible to install a cooler from another laptop?

Theoretically yes, but you need to consider:

1) Matching power connectors (usually 3-pin or 4-pin PWM).

2) Dimensions - the cooler must fit into the case.

3) Performance - more blades ≠ better cooling (airflow and static pressure are important).

It is better to look for the model recommended for your laptop on the forums (for example, NotebookReview or Reddit/r/laptops).

6. External solutions: cooling pads and other accessories

If you don’t want to disassemble your laptop, external accessories will help reduce the temperature by 3–10°C.

  • 💻 Cooling pad. Models with active airflow (built-in fans) are more efficient than passive ones. Best options:
    • Cooler Master NotePal X3 — 3 fans, speed adjustment.
    • IETS GT500 — metal case, quiet 200 mm cooler.
    • DeepCool N60 - budget option with USB power.
  • 🧊 Thermal pads. Graphite or aluminum plates (eg. IC Graphite Thermal Pad) are glued to the bottom cover of the laptop and remove heat.
  • 🔌 USB fans. Compact solutions like Arctic Breeze Mobile attached to the screen and blows air over the keyboard.
  • 🏠 Workplace organization. Place the laptop on hard surface (not on a bed or sofa), provide a gap of 5-10 cm on all sides for air circulation.

Disadvantages of external solutions:

  • ❌ Additional noise (active stands can buzz louder than the stock cooler).
  • ❌ Dependency on the USB port (some stands take up a slot that could be used for a mouse or flash drive).
  • ❌ Limited efficiency - external airflow will not save you from overheating during acceleration or in hot climates.
💡

Cooling pads are most effective for laptops with bottom vents (such as ASUS TUF Gaming, MSI GF63). In models with side airflow (for example, MacBook Pro M1) they are practically useless.

7. Extreme methods: overclocking, modding and liquid nitrogen

For enthusiasts willing to take risks, there are radical ways to improve cooling:

  • ❄️ Liquid cooling. Some laptops (Clevo, Eurocom) you can install a full-fledged water block with a pump and an external radiator. Cost - from 15,000 ₽, temperature reduction - up to 30°C.
  • ⚡ Extreme overclocking with phase change. Used in benchmarking: the processor is cooled with liquid nitrogen (−196°C) to achieve record frequencies. Applicable for short-term tests only!
  • 🔧 Case modding. Cutting additional ventilation holes or installing a second cooler. Popular with owners Alienware And MSI GT.
  • 🔄 Replacing the thermal interface with gallium. The metal, with a melting point of 29°C, provides better thermal conductivity than thermal paste, but requires careful application.

Modding example:

User with Reddit modified ASUS ROG Strix G15, installing a custom water cooling system with an external radiator from Corsair H100i. Temperature RTX 3070 under load dropped from 88°C to 65°C, and cooler noise decreased by 40%.

⚠️ Attention: Liquid cooling in a laptop requires a sealed system. The slightest leak can damage the motherboard. Such modifications are recommended only for experienced users or under the guidance of a specialist.

8. When to contact service: signs of serious problems

Not all cooling problems can be solved on your own. Contact the service center if:

  • 🔥Laptop turns off immediately after turning on (the bridge or video card may have burned out due to overheating).
  • 💨 Cooler doesn't rotate at all or makes a grinding noise (bearing failure).
  • 🔋 The laptop does not turn on without a power supply, even if the battery is charged (the power circuit may be damaged due to overheating).
  • 📉 CPU temperature exceeds 100°C when idle (probably the radiator has fallen off or the heat pipe has cracked).

Average prices for repairs in Moscow (2026):

Service Cost (₽) Deadline
Cleaning + replacing thermal paste 1 500–3 000 1–2 days
Cooler replacement 2,000–5,000 (with spare part) 2–3 days
Heat pipe repair 4 000–8 000 3–5 days
Replacing the GPU/CPU chip (if overheated) 10 000–30 000 5–10 days

How to choose a service:

  • 🔍 Check reviews on Yandex.Maps or 2GIS. Pay attention to the before/after photos.
  • 📋 Ask if the work is guaranteed (minimum 3 months).
  • 💬 Check whether they use original spare parts or analogues.
💡

If the laptop is under warranty, do not disassemble it yourself! In most cases, cleaning and replacing thermal paste is not considered a warranty case, but traces of tampering may cause a refusal to repair.

FAQ: Frequently asked questions about laptop cooling

Is it possible to use a hair dryer to clean dust from a laptop?

No! A household hair dryer creates too much air flow, which can damage the fan blades or blow small components off the board. Use only compressed air can or a special vacuum cleaner for electronics with power control.

How often should you change the thermal paste in your laptop?

Depends on the type of paste and operating conditions:

  • Silicone (Arctic MX-4) - once every 2–3 years.
  • Metal (Kryonaut) - once every 1–1.5 years (dries faster).
  • Liquid metal (Conductonaut) - once every 5 years, but requires careful application.

In gaming laptops (eg. MSI Raider, Alienware m16) Thermal paste should be checked once a year due to high loads.

Do "cooling stickers" on the laptop case help?

Passive stickers (eg. Cooler Master Notepal U Stand) give a minimal effect - a decrease in temperature by 1–3°C. They are only useful in combination with other methods (cleaning, thermal paste). Active solutions (with a USB fan) are more efficient, but take up port space.

Can I use automotive thermal paste on a laptop?

Absolutely not! Automotive thermal pastes (for example, ABRO) contain abrasive particles and conduct electricity, which may cause a short circuit. Use only pastes intended for electronics.

Why does my laptop get hot even when idle?

Possible reasons:

  • 🔍 Background processes (mining viruses, Windows updates).
  • 🔋 Battery malfunction (it can heat up the case).
  • 💨 The ventilation holes are clogged or the temperature sensor is broken.
  • 📥 BIOS has changed to an aggressive cooling profile (try resetting the settings).

Start by checking in Task Manager and cleaning the laptop.
