Is your laptop overheating? Effective Ways to Improve Cooling

Laptops get hot - that's a fact. Even new models with top processors Intel Core i9 or AMD Ryzen 9 under load they can heat up to 95–100°C, which leads to throttling (automatic performance degradation), sudden shutdowns or component degradation. But if your laptop turns into a “stove” even when watching videos or working in Excel, the problem requires intervention.

In this article - practical methodsHow to improve laptop cooling without contacting a service center. We will analyze both software solutions (BIOS settings, fan control) and hardware solutions (cleaning, thermal paste, stands), and also tell you when Replacing the cooling system with liquid metal thermal paste can reduce temperatures by 15–20°C, but at the same time risky for beginners. All tips are tested on models ASUS ROG Zephyrus, Lenovo Legion, MacBook Pro and budget Acer Aspire.

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

Before taking action, make sure that the problem is indeed overheating. The symptoms are often confused with viruses or battery problems. Please note:

• 🔥 Hot case in the area of the keyboard (especially on the left - there is usually a processor there) or below (video card).
• 💻 Sudden brakes in games or rendering, although before everything worked stably.
• 🔄 Spontaneous reboots under load (overheat protection is triggered at a temperature of ~105°C).
• 🎛️ Loud fans even in simple tasks (for example, in Google Chrome with 5 tabs).

For accurate diagnosis, use monitoring programs:

• HWMonitor — shows the temperature of all processor cores, video cards and disks.
• MSI Afterburner — convenient for gamers (displays FPS and temperature in the game).
• Core Temp — a minimalistic utility for monitoring only the CPU.

Critical values for modern processors:

Processor type	Max. operating temperature	Throttling temperature
Intel Core i3/i5/i7 (12th–14th generation)	up to 100°C	100°C+
AMD Ryzen 5/7/9 (5000–7000 series)	up to 95°C	90°C+
Apple M1/M2/M3	up to 100°C	105°C+ (rare)
Budget Celeron/Pentium	up to 90°C	95°C+

⚠️ Attention: If the processor temperature rises to 90°C+ while idle (without running programs), this is a sign critical fault - for example, peeling thermal paste or a non-working cooler. Immediately turn off the laptop and contact service.

2. Cleaning the cooling system: dust is the main enemy

Dust and pet hair clog radiators and fan blades, reducing cooling efficiency by up to 30–50%. Cleaning is recommended every 6–12 months, and for gaming laptops - once every 3-4 months.

How to clean your laptop from dust indiscriminately:

• 🧹 Use compressed air can (For example, WD-40 Specialist). Blow in short bursts (2–3 seconds) into the ventilation grilles from a distance of 10–15 cm.
• 🔄 Before cleaning turn off the laptop and remove the battery (if it is removable).
• 🌀 For hard to reach places use soft brush (for example, for makeup).
• 🚫 Do not use a vacuum cleaner - it creates static electricity that can damage components.

Turn off the laptop and disconnect the charger|Remove the battery (if possible)|Prepare a can of compressed air|Secure the fan blades (so as not to unwind)|Clean outdoors or on a balcony-->

If superficial cleaning does not help, you will need laptop disassembly to remove dust from the radiator and replace thermal paste. This is a complicated procedure - for models Dell XPS or MacBook Air You may need a special tool (pentalobe screwdriver). Don't take risks, if you are not confident in your skills.

What to do if dust cannot be removed with a spray can?

If the dust is compacted into a dense layer (often happens in laptops older than 3 years), disassembly will be required. The service calls this service “full cleaning of the cooling system” and it costs from 1,500 to 3,000 rubles, depending on the model. An alternative is to use isopropyl alcohol (90%+) and cotton swabs to gently remove dirt from the fan blades, but this is a temporary solution.

3. Replacing thermal paste and thermal pads

Thermal paste is a heat-conducting material between the processor/video card and the heatsink. Over time, it dries out and becomes less effective. In budget laptops (Acer Nitro 5, HP Pavilion) Thermal paste is sometimes applied poorly from the factory, which leads to overheating out of the box.

How to understand when it's time to change thermal paste:

• 📉 Idle temperature is above 50–60°C (with normal pasta - 35–45°C).
• 🔥 Sudden temperature changes under minimal load (for example, when opening Word).
• 🕒 The laptop is more than 2-3 years old, and cleaning did not help.

Which thermal paste to choose:

Type	Examples of brands	Thermal conductivity	Difficulty of application
Standard	Arctic MX-6, Noctua NT-H2	10–12 W/mK	Easy
High performance	Thermal Grizzly Kryonaut	12–14 W/mK	Medium (requires running in)
Liquid metal	Thermal Grizzly Conductonaut	73 W/mK	Difficult (risk of short circuit!)
For MacBook	Arctic MX-4 (no metal particles)	8–10 W/mK	Easy

Liquid metal thermal paste (Conductonaut, Coollaboratory Liquid Ultra) gives the best result, but dangerous:

• 🚨 If applied incorrectly, it may short-circuit the contacts on the motherboard.
• 🔧 Requires complete disassembly of the laptop and protection of components Kapton tape.
• 💰 The cost of work in the service is from 3,000 rubles (excluding pasta).

⚠️ Attention: If you decide to apply liquid metal yourself, never use aluminum foil for protection - it conducts current. Only Kapton or special tape 3M Polyimide.

4. Setting up BIOS and power management

Many laptops run in maximum performance mode by default, which leads to excessive heat. Optimizing BIOS and Windows settings can reduce temperatures by 10–15°C without any noticeable loss of performance.

What to change in BIOS (UEFI):

• 🔧 Disable Turbo Boost (for Intel) or Precision Boost (for AMD). This will reduce peak performance by 5-10%, but the temperature will drop by 15-20°C.
• 📉 Install Power Limit (PL1/PL2) 80–90% of the maximum (for example, for i7-12700H from 45 W to 35–40 W).
• 🔄 Turn it on Cool'n'Quiet (AMD) or SpeedStep (Intel) for dynamic clock control.

How to get into the BIOS:

• For Windows: Settings → Update & Security → Recovery → Restart Now (in the boot menu select UEFI Firmware Settings).
• For MacBook: hold Option (Alt) + Command + P + R when turned on.

Windows settings to reduce heat:

• 🪟 Select power plan Balanced or Energy Saving (in Control Panel → Power Options).
• 🖥️ Disable background applications: Settings → Privacy → Background apps.
• 🎮 For gamers: limit FPS in games to 60–90 (in settings NVIDIA Control Panel or Radeon Software).

5. Cooling pads and external coolers

External accessories are not a replacement for cleaning or replacing thermal paste, but they can improve the situation 5–10°C. Especially useful for laptops with poor cooling systems (MSI GF63, HP Omen 15).

Stand types:

• 💨 Passive (without fans) - raise the laptop for better air circulation. Cheap (from 500 ₽), but ineffective.
• 🌀 Active (with 1–5 fans) – reduces the temperature by 5–8°C. Best models: Cooler Master NotePal X3, IETS GT500.
• 💻 With USB hub — additionally provide ports (for example, Havit HV-F2056).

How to choose a stand:

• 📏 The size must match the laptop (15.6" or 17.3").
• 🔌 Powerful stands (with 3+ fans) require separate USB power.
• 🎯 For gamers, it is better to choose a model with adjustable fan speed.

An alternative to stands - USB coolers (For example, AC Infinity MultiFan S5), which are attached to the ventilation grilles of the laptop. They are cheaper (from 1,000 ₽), but less versatile.

6. Software control of fans

By default, fans in laptops operate according to a conservative algorithm so as not to make noise. But under load this is often not enough. Special utilities allow manually control the speed of coolers or set aggressive cooling profiles.

Popular programs:

• 🖥️ Fan Control is a free utility that supports most laptops (including ASUS, Lenovo, MSI).
• 🎮 MSI Afterburner — allows you to control GPU (video card) coolers.
• 🍎 Macs Fan Control - for MacBook Pro/Air (adjusts fans and temperature thresholds).
• 🔧 SpeedFan - outdated, but works on older models (Dell Inspiron, HP ProBook).

How to set up Fan Control:

1. Download the program from the official website getfancontrol.com.
2. Select your laptop from the list of supported devices.
3. Set speed curves (eg 100% at 80°C instead of the standard 90°C).
4. Save the profile and run it as an administrator.

⚠️ Attention: Do not set the maximum speed of the fans on a constant basis - this will shorten their life. Optimal: 60–70% at idle, 90–100% under load.

For laptops ASUS ROG And Lenovo Legion There are proprietary utilities:

• Armoury Crate (ASUS) - allows you to select profiles Silent, Balanced or Turbo.
• Lenovo Vantage - setting Thermal Mode (recommended Balanced or Performance with TDP limitation).

7. Alternative cooling methods

If standard methods do not help, consider less obvious solutions:

Undervolting (lower CPU voltage):

• 🔌 Use ThrottleStop (for Intel) or Ryzen Controller (for AMD).
• 📉 Reducing the voltage by 50–100 mV can give -10°C without loss of performance.
• ⚠️ Risk: with incorrect settings, failures are possible (but not failure).

Replacing thermal pads:

• 🔧 Thermal pads (between the heatsink and memory/VRM chips) harden over time.
• 🛠️ Replace them with Thermal Grizzly Minus Pad 8 (thickness 0.5–1 mm).
• 💡 Effect: reduction in GPU temperature by 5–8°C.

Cooling system modding:

• 🔄 Installation of additional copper shims (heat pipes) - difficult, but effective for old laptops.
• 💧 Replacing thermal paste with liquid metal (see section 3).
• 🌀 Installation external radiator (For example, Cooling Pad with Liquid Cooling) - exotic, but it works.

What is a laptop "reset"?

Repad is the replacement of all thermal pads in a laptop with better ones. For example, in MSI GE76 Raider After the reset, the GPU temperature in games drops from 88°C to 75°C. The procedure requires complete disassembly and costs from 2,500 rubles in service.

8. When is it time to take your laptop to a service center?

Not all cooling problems can be solved on your own. Contact a specialist if:

• 🔥CPU temperature exceeds 100°C in idle time.
• 🔊 Fans don't turn on at all (check in BIOS).
• 💥Laptop turns off after 5–10 minutes after switching on.
• 🛠️ Replacement required cooler (for example, in MacBook Pro 2015–2017 this is a common problem).
• 🔧 Needs to be re-soldered south/north bridge (relevant for older laptops with NVIDIA Optimus).

Cost of repairs in service (Moscow, 2026):

Service	Price (₽)	Time (hours)
Cleaning + replacing thermal paste	1 500–3 000	1–2
Fan replacement	2 000–4 500	2–3
Repad (replacing thermal pads)	2 500–5 000	3–4
Liquid metal thermal paste	3 000–6 000	4–5
Replacing the cooling system	5 000–12 000	5–7

Before visiting the service:

• 📋 Make a backup of your data - sometimes you need to disconnect the drive.
• 🔍 Check if the masters use original spare parts (for example, coolers from Delta or Sunon).
• 💰 Compare prices in 2-3 services - the spread can be 2 times!

💡

If the laptop is more than 5 years old, it is sometimes cheaper to buy a new one than to repair the cooling system. For example, replacing a cooler in Dell Latitude E6440 may cost 70% of the price of a used analogue.

FAQ: Frequently asked questions about laptop cooling

🔥 Is it possible to use a laptop on a soft surface (blanket, sofa)?

No! Soft surfaces block ventilation holes, causing overheating. Always use firm and smooth surface. If you need to work on the bed, buy stand with legs or at least put the laptop on book to improve air circulation.

❄️ Do “cooling stickers” on the case help?

Stickers with gel or metallized surface (Cooler Master Notepal U Stand) give minimal effect (1–3°C). They can only help in conjunction with other methods (cleaning, stand). Don't waste money on them as your primary solution.

🎮 Why does the laptop get hot even in simple games (for example, CS:GO)?

The reasons may be different:

• 🔧 Throttling — the processor or video card automatically reduces the frequency due to overheating.
• 🖥️ Background processes — check the Task Manager for presence svchost.exe or Antimalware Serviceconsuming CPU.
• 🔄 Old drivers - update GPU drivers via NVIDIA GeForce Experience or AMD Adrenalin.
• 💥 GPU failure — if the video card temperature rises to 95°C+ in the game menu, this is a sign of cooling problems.

💻 How to check if the fan in a laptop is working?

Methods:

1. Listen - when under load you should hear the noise of the cooler.
2. Touch the exhaust grille - warm air should flow out.
3. Use HWMonitor — fan speed (RPM) should increase as it heats up.
4. Go to the BIOS - some models show the status of the coolers.

If the fan does not turn on, possible reasons: clogged with dust, the engine burned out or cable disconnected.

🛠️ Is it possible to replace the cooler in a laptop yourself?

Theoretically yes, but:

• 🔧 Most laptops require complete disassembly (removing the motherboard).
• 🔍 Coolers often individual for each model (for example, for Lenovo ThinkPad T480 And T490 they are different).
• ⚠️ Risk of damage trains or capacitors on the board.

If you do not have experience, it is better to entrust this to the service. The exception is laptops with modular design (For example, Framework Laptop), where the cooler is replaced in 5 minutes.
