The laptop constantly overheats: what to do to cool it yourself

Laptop overheating is a problem that every second user faces. Even new models ASUS ROG, Lenovo Legion or MacBook Pro can heat up to 90–100°C under intense loads, which leads to throttling (automatic performance degradation), sudden shutdowns, or even component damage. But in 80% of cases, the causes of overheating lie not in factory defects, but in improper operation or outdated settings.

In this article we will look at 12 proven methodsHow to cool a laptop without disassembling - from basic (cleaning vents) to advanced (setting up TDP processor and undervolting). You will also find out what temperatures are considered critical for modern chips Intel Core i7/i9 And AMD Ryzen 7/9, and how to control them using free utilities. If your laptop turns into a “stove” even when working in Word - these recommendations will help return him to normal temperature.

1. Check the current temperature: norms and critical value

Before taking action, you need to understand how serious the problem is. Normal temperatures for a laptop depend on the model and load:

• 📱 Idle mode (working with documents, surfing): 35–50°C.
• 🎮 When gaming/rendering: 70–85°C (for Intel And AMD latest generations).
• ⚠️ Critical threshold: 95–105°C - at this temperature it works thermal throttling (forced reduction of frequencies).

To measure temperature, use the programs:

• 🔥 HWMonitor — shows the temperature of all cores, video card and disk.
• 📊 Core Temp - specializes in processors Intel/AMD.
• 🎮 MSI Afterburner — convenient for gamers (displays FPS and temperature in the game).

Processor	Max. permissible temperature	Throttling starts with
Intel Core i5/i7 (12th–13th generation)	100°C	90°C
AMD Ryzen 7/9 (5000/6000 series)	95°C	85°C
Apple M1/M2	105°C	95°C
Intel Core i3/i5 (up to 10th generation)	90°C	80°C

If your laptop regularly gets hot 85°C+ in simple tasks (for example, when viewing YouTube), this is a cause for concern. Most likely the problem is clogged cooling system or incorrect power settings.

2. Cleaning the vents and cooler: step-by-step instructions

The main reason for overheating is dust and dirt, accumulating in the radiator and fan blades. Even in a clean room, after a year of using a laptop, a layer of dust accumulates inside, which blocks the air flow. You can do the cleaning yourself without completely disassembling the device.

What you will need:

• 🪥 A can of compressed air (for example, Air Duster).
• 🔧 Screwdriver (if you need to remove the bottom cover).
• 🧴 Cotton swabs and alcohol for cleaning the blades.

Step by step process:

1. Turn off the laptop and disconnect the battery (if it is removable).
2. Turn the unit over and locate the ventilation grilles (usually on the side or bottom).
3. In short bursts (2-3 seconds each), blow through the grates with a spray can, holding it at an angle 45°.
4. If there is a lot of dust, carefully rotate the fan blades with your finger and repeat the blowing.
5. For deep cleaning, remove the bottom cover (if you have experience) and remove dust from the radiator.

⚠️ Attention: Do not use a vacuum cleaner to clean your laptop! Static electricity can damage the motherboard. Also avoid liquid cleaners - they can get on the contacts.

After cleaning, the idle temperature should drop by 5–15°C. If there is no improvement, the problem may lie in dried thermal paste or faulty cooler.

3. Optimizing power settings: how to reduce heat without losing performance

Windows and macOS default to power plans that aren't always optimal for cooling. For example, the “Maximum Performance” mode forces the processor to operate at maximum frequencies even in simple tasks, which leads to unnecessary heating.

For Windows:

1. Open Control Panel → Power Options.
2. Select scheme "Balanced" or "Energy Saving».
3. Click "Setting up the power plan» → «Change advanced settings».
4. Find the section "Processor power management" and install:
• Max. CPU status: 90% (instead of 100%).
• Minimum condition: 5%.

For macOS:

• Open System Settings → Battery.
• Turn on the "Optimized battery charging» (reduces heating during charging).
• Disable "Automatic launch of graphically intensive programs» in the monitor settings.

These settings will reduce the temperature by 5–10°C without any noticeable drop in performance. For gamers and designers, it is better to use specialized utilities like ThrottleStop (for Intel) or Ryzen Controller (for AMD).

4. Undervolting: how to reduce processor voltage and reduce heat

Undervolting - This is a reduction in the voltage supplied to the processor without loss of performance. The method is especially effective for laptops with Intel Core i7/i9 And AMD Ryzen 7/9, where the factory settings are often too high.

Instructions for Intel (using ThrottleStop):

1. Download ThrottleStop from the official website and run as administrator.
2. In the section FIVR find the parameter CPU Core And CPU Cache.
3. Decrease the value by 50–100 mV (for example, with 1.250V to 1.150V).
4. Click Apply and check the stability in a stress test (AIDA64 or Prime95).

Instructions for AMD (using Ryzen Controller):

1. Install Ryzen Controller and open the tab Power.
2. In the section CPU Voltage Offset set value -50 mV.
3. Save the settings and check the temperature under load.

⚠️ Attention: Do not reduce the voltage by more than 100 mV in one step - this can lead to unstable work or blue screens. If the laptop starts to crash, return to the previous settings.

If undervolting is successful, the processor temperature under load will decrease by 10–20°C, and the battery life will increase by 10–15%.

5. Replacing thermal paste: when is it necessary and how to do it correctly

Thermal paste is a heat-conducting material between the processor and the heatsink. Over time, it dries out and becomes less effective. If the temperature remains high after cleaning the dust, it's most likely time to replace the thermal paste.

Signs that the thermal paste has dried out:

• 🔥 The laptop heats up to 90°C+ in simple tasks.
• 📉 Temperature fluctuates (for example, from 60°C to 95°C in seconds).
• 🕒 The laptop began to turn off more often due to overheating.

Which thermal paste to choose:

Type	Examples	Temperature effect
Standard	Arctic MX-4, Noctua NT-H1	Decrease by 3–7°C
Liquid metal	Thermal Grizzly Conductonaut	Decrease by 10–15°C
Ceramic	Arctic Ceramique	Decrease by 2–5°C

How to replace thermal paste:

1. Turn off the laptop, remove the battery and bottom cover.
2. Carefully disconnect the cooler and remove the heatsink from the processor.
3. Remove old paste with a cloth soaked in isopropyl alcohol.
4. Apply a thin layer (about the size of a pea) of the new paste to the center of the processor.
5. Reassemble the laptop and check the temperature.

What happens if you apply too much thermal paste?

Excess paste can leak past the edges of the processor, onto the motherboard contacts and cause a short circuit. Also, a thick layer impairs thermal conductivity, since the air in the paste acts as an insulator.

Liquid metal paste gives the best results, but is difficult to apply - it conducts electricity and can damage the board if used carelessly. For beginners it is better to choose Arctic MX-4 or Noctua NT-H1.

6. Software cooling methods: utilities for controlling fan and frequencies

If hardware methods do not help, you can optimize cooling using software. They allow you to manually adjust the cooler speed, limit processor frequencies, and even disable unnecessary background processes.

Top 5 programs for cooling a laptop:

• 🌀 SpeedFan — controls fan speed (supports most models).
• 🎛️ MSI Afterburner — control over the GPU and video card cooler.
• ⚡ ThrottleStop — fine-tuning voltage and frequencies for Intel.
• 🔄 Ryzen Master - official utility for AMD Ryzen.
• 🧹 Process Lasso — limits resource-intensive processes.

How to set up SpeedFan for maximum cooling:

1. Run the program as administrator.
2. In the tab Readings find the temperature readings (CPU, GPU).
3. In the section Speeds increase the value PWM for coolers up to 80–100%.
4. Save the settings as a preset and apply them under high loads.

For gamers it is useful to combine MSI Afterburner (for video card) and ThrottleStop (for processor). For example, in games you can limit FPS to 60–90to reduce GPU load and heat.

7. External cooling devices: stands and coolers

If internal cooling fails, external accessories will help. They are especially useful for thin ultrabooks (MacBook Air, Dell XPS), where the cooling system is limited by the dimensions of the case.

Types of cooling pads:

• 💨 Passive - without fans, improve air circulation (for example, IKEA Laptop Stand).
• 🌀 Active — with 1–5 fans, powered by USB (for example, Cooler Master NotePal X3).
• 🎮 Gaming - with backlight and speed control (for example, Razer Chroma).

How to choose a stand:

Parameter	Recommendation
Size	Corresponds to the diagonal of the laptop (for example, 15.6" for most laptops).
Number of fans	For office tasks - 1–2, for games - 3–5.
Noise level	No more 25 dB (quiet models: Tree New Bee).
Additional features	USB hub, height adjustment, backlight.

Fan stand reduces temperatures by 5–12°C, and passive - on 2–5°C. For maximum effect, combine it with cleaning the internal cooler and replacing thermal paste.

8. When to contact service: signs of serious problems

If you have tried all the methods and the laptop is still overheating 95°C+ in simple tasks, the problem may be hardware. Here are the signs that it’s time to take your device to service:

• 🔥 The cooler operates at maximum speed, but the temperature does not drop.
• 💥 The laptop turns off spontaneously (even after cleaning and replacing the paste).
• 🔊 There is an unusual noise (grinding, crackling) - the fan bearings may have broken.
• 📉 Productivity dropped by 2-3 times for no apparent reason.

Possible malfunctions:

• 🔧 Faulty cooler - requires replacement.
• 🔥 Damaged radiator (for example, after a fall).
• 🔌 Problems with the motherboard (incorrect processor power supply).
• 🔋 Swollen battery - May block air flow.

The cost of repair depends on the problem:

• Cooler replacement: 1 500–4 000 ₽.
• Replacing thermal paste in the service: 1 000–2 500 ₽.
• Radiator repair: 3 000–8 000 ₽.

⚠️ Attention: If the laptop is under warranty, do not disassemble it yourself! Most manufacturers (Apple, HP, Dell) will void the warranty if the case is opened. Contact an authorized service center.

FAQ: Frequently asked questions about laptop overheating

❓ Why does the new laptop heat up more than the old one?

Modern processors (Intel 12th–13th generation, AMD Ryzen 6000) have high transistor density and TDP up to 45–65 W, which leads to greater heat generation. Also, thin ultrabooks use compact cooling systems that cope worse with the load.

❓ Is it possible to use a laptop without a battery so that it does not heat up?

Yes, but this is a temporary solution. The battery itself heats up slightly (about 2–5°C), and the main heat source is the processor and video card. However, if the battery is swollen, it necessarily needs to be replaced as it may block air flow.

❓ What temperature should the laptop be when charging?

When charging, the temperature may rise by 5–10°C due to additional load on the power controller. Norm: 40–60°C. If the laptop gets hotter, check the cable and power supply - a faulty charger may cause overheating.

❓ Does a cooling pad for a MacBook help?

Yes, but the effect is less than on Windows laptops. MacBook Pro/Air have an optimized cooling system, but the stand can reduce the temperature by 3–7°C at high loads (for example, in Final Cut Pro). For maximum effect, choose models with a metal base (for example, Rain Design mStand).

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

No! The hair dryer creates too much air flow, which can damage the fan blades or blow small parts off the board. Use only compressed air can or a soft brush.
