Laptop overheating is a problem that every second user faces. Even new models Dell XPS, MacBook Pro M3 or gaming MSI Katana can heat up to 90–100°C under load, which leads to throttling (automatic performance degradation), sudden shutdowns, or component damage. But in 80% of cases, the reasons lie not in factory defects, but in incorrect operation or settings.

In this article - proven methods reduce the temperature of the laptop, from basic (cleaning dust) to advanced (undervolting and replacing thermal paste). We'll figure out why they're heating up. Intel Core i7/i9 stronger AMD Ryzen 7how does it affect heating Turbo Boost, and what to do if the fans are running at maximum, but there is no cooling. All recommendations are based on tests of real devices and data from AIDA64, HWMonitor, ThrottleStop.

1. Causes of laptop overheating: diagnosis before treatment

Before cleaning your laptop or changing thermal paste, you need to understand what exactly is being heated and why. The main “culprits” of high temperatures:

  • 🔥 Processor (CPU) - heats up to 100°C upon activation Turbo Boost (especially in Intel Core i7-13700H or Ryzen 9 7940HS).
  • 🎮 Video card (GPU) - in games (Cyberpunk 2077, Alan Wake 2) or rendering (Blender, Adobe Premiere) can reach 85–95°C.
  • 🖥️ Chipset/bridges - get hot when working with PCIe 4.0/5.0 (for example, when connecting an external video card via eGPU).
  • 🔋 Battery - if the laptop is not disconnected from the network, the battery can heat up to 50–60°C, increasing overall overheating.

How to check the temperature? Use the utilities:

  • 📊 HWMonitor — shows the temperature of all CPU cores, GPU, disks.
  • 🛠️ ThrottleStop — analyzes throttling and frequencies Intel-processors.
  • 🔍 AIDA64 (stability test) - loads the system and records peak temperatures.
📊 How often does your laptop overheat?
  • Only in games/rendering
  • During long-term work (office, browser)
  • Constantly, even when idle
  • Doesn't heat up/don't know

Critical temperatures for modern laptops:

Component Norm (load) Dangerous threshold Maximum (throttling)
Intel Core i7/i9 70–85°C 90°C 100°C (automatic shutdown)
AMD Ryzen 7/9 65–80°C 85°C 95°C
NVIDIA RTX 30/40 70–80°C 85°C 90°C+ (throttling)
Apple M1/M2/M3 50–70°C 80°C 105°C (rare, but possible)
⚠️ Attention: If the CPU/GPU temperature exceeds 95°C in idle time (without load), this is a sign cooling system malfunction — urgent diagnosis is required!

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

Dust is the main cause of overheating in 60% of cases. It clogs radiators, reduces fan efficiency and impairs heat dissipation. Cleaning needs to be done every 6–12 months, and for gaming laptops (ASUS ROG, MSI Raider) - once every 3–4 months.

What you will need:

  • 🪛 Screwdriver (usually Phillips #0 or T5 for MacBook).
  • 🌬️ A can of compressed air (for example, WD-40 Specialist).
  • 🧹 Soft brush (for cleaning fan blades).
  • 🧴 Isopropyl alcohol (70%+) and cotton swabs (for cleaning contacts).

1. Turn off the laptop and remove the battery (if removable)

2. Unscrew the back cover (find the diagram for your model on iFixit)

3. Blow out the radiators and fans with compressed air (hold the blades so they don’t spin!)

4. Remove dust from the cooler with a brush

5. Wipe the thermal paste contacts with alcohol (if you are changing the paste)

6. Reassemble the laptop and check the temperatures in HWMonitor-->

Features for different brands:

  • MacBook Pro/Air: Requires special P5 Pentalobe screwdriver The battery is glued - remove it carefully!
  • Lenovo Legion/HP Omen: Clips are often used instead of screws - do not break the plastic.
  • Acer Predator: Radiators with copper tubes - blow at an angle to avoid bending.
⚠️ Attention: Do not use a vacuum cleaner to clean your laptop! Static electricity can damage the motherboard. Also avoid wet wipes - they leave streaks on the contacts.

3. System optimization: reducing the processor load

If the laptop gets warm even after cleaning, the problem may be software load. Modern OS (Windows 11, macOS Sonoma) and background processes often load the CPU by 20–30% for no apparent reason. Here's how to fix it:

🔧 Windows settings to reduce heat

  • 🛑 Disable unnecessary startups: Ctrl+Shift+Esc → Task Manager → Startup. Remove NVIDIA Telemetry, Microsoft OneDrive, Adobe Creative Cloud.
  • 🔄 Change your power plan: Control Panel → Power Options → Advanced Settings → Maximum CPU Performance → install 90% instead of 100%.
  • 🚫 Disable Turbo Boost (for Intel): in ThrottleStop uncheck Turbo Boost or use Power Plan → Battery Saver.

🍎 macOS: how to reduce heat MacBook

  • 🔍 Check CPU activity: Monitor → Activity Monitor → CPU. Close kernel_task (if it loads more than 100%).
  • 🔋 Disable Automatic Graphics Switching: System Settings → Battery → Power Saving Mode.
  • 🛠️ Reset SMC (for MacBook 2018 and older): turn off the laptop, hold down Control+Option+Shift + power button for 10 seconds.
💡

If your laptop gets hot when playing games, try limiting FPS via NVIDIA Control Panel (maximum 60–90 fps) or RTSS. This will reduce the load on the GPU by 15–20%.

Temperature control programs:

  • 📉 Fan Control — manual adjustment of fan speed (supports ASUS, Lenovo, HP).
  • ⚡ Undervolt - reduces the voltage on the CPU (Intel up to the 10th generation, AMD Ryzen with restrictions).
  • 🎛️ MSI Afterburner — controls GPU frequencies and limits energy consumption (Power Limit).

4. Replacing thermal paste and thermal pads

Thermal paste dries out over time, losing thermal conductivity. As a result, the CPU/GPU temperature increases by 10–20°C. Paste service life — 2–3 years (in gaming laptops — 1–1.5 years). How to replace it:

Which thermal paste should I choose?

Paste type Thermal conductivity Service life Top brands
Silicone 3–5 W/mK 1–2 years Arctic MX-4, Noctua NT-H1
Metal (liquid metal) 70–80 W/mK 5+ years Thermal Grizzly Conductonaut
Ceramic 1–2 W/mK 3–4 years Arctic Silver 5
Carbon 10–12 W/mK 3 years Thermal Grizzly Kryonaut

Step by step replacement:

  1. Remove the back cover of the laptop (see section 2).
  2. Disconnect the battery (required!).
  3. Remove the cooling system (radiator + fan).
  4. Remove old paste with alcohol and a lint-free cloth.
  5. Apply a thin layer of new paste (pea-sized for CPU, strip for GPU).
  6. Replace the thermal pads on the VRM chips (if they are cracked).
  7. Reassemble the laptop and check temperatures under load.
What happens if you apply too much thermal paste?

Excess paste creates air bubbles that impair heat dissipation. Temperatures may rise by 5–10°C. The paste can also leak onto the motherboard and cause a short circuit (especially liquid metal!).

⚠️ Attention: Liquid metal (Conductonaut) cannot be used on aluminum radiators - it corrodes them! For copper surfaces only.

5. Undervolting: reducing processor voltage

Undervolting - this is a reduction in the voltage supplied to the CPU/GPU without loss of performance. On Intel-processors (up to 12th generation) and AMD Ryzen (with limitations) this allows you to reduce the temperature by 10–15°C and increase battery life.

How to do undervolting:

  • 📥 Download ThrottleStop (for Intel) or Ryzen Controller (for AMD).
  • 🔧 B ThrottleStop go to the tab FIVR.
  • 📉 Reduce CPU Core And CPU Cache on 50–100 mV (start with -50 mV and test stability).
  • 🔄 Save your profile and check the temperatures in Prime95 or Cinebench R23.

Undervolting results using an example Intel Core i7-10750H:

Parameter Standard voltage After undervolting (-100 mV)
Temperature (load) 92°C 78°C
Energy consumption 45 W 38 W
Performance (Cinebench) 1250 points 1240 points (no losses!)
💡

Undervolting is safe if you reduce the voltage gradually (10–20 mV increments) and test stability. On Intel 13th/14th generation And AMD Ryzen 7000 The function is blocked by the manufacturer.

6. External cooling: racks, stands and coolers

If internal methods don't help, use external accessories. They reduce the temperature by 5–15°C, are especially effective for laptops with poor cooling systems (MacBook Pro 13", Lenovo IdeaPad).

Top 5 Cooling Accessories:

  • 💨 Cooler Master NotePal X3 - stand with 180mm fan, reduces temperature by 8–12°C.
  • ❄️ IETS GT500 — rack with 5 fans and speed control.
  • 🖥️ Havit HV-F2056 — budget stand with backlight and USB hub.
  • 🔋 Tree New Bee Cooling Pad — silent model with 6 fans.
  • 🎮 Corsair Lapdog - for gaming laptops (ASUS ROG, Alienware) with keyboard and mouse support.

How to use the cooling pad correctly:

  • 🔌 Connect to USB 3.0 (not 2.0) - this way the fans get enough power.
  • 📏 Install the laptop so that the air intake holes do not overlap.
  • 🌡️ Use with the program Fan Control to synchronize speeds.
⚠️ Attention: Cheap stands with plastic fans (<1000 rub.) often break after 2–3 months. Choose models with metal blades and speed control.

7. Extreme measures: throttling and replacing the cooling system

If the laptop gets hot 100°C even after all the manipulations, radical methods remain:

  • 🔨 Replacing thermal pads - in laptops MSI, Gigabyte Cheap gaskets are often used, which harden after a year.
  • 🔄 Cooling system modding — installation of copper shims (thermal pads) on VRM and chipset (relevant for RTX 30/40 series).
  • 🛠️ Replacing fans - in MacBook Pro 2018–2020 Coolers often break due to dust.
  • ⚡ CPU/GPU throttling - forced frequency limitation via BIOS or ThrottleStop.

How to throttle the processor in BIOS:

  1. Reboot your laptop and enter BIOS (F2, Del or Esc when loading).
  2. Find a section Advanced → CPU Configuration.
  3. Install TDP Limit on 25–35 W (for Ultrabook) or 45–65 W (for gaming laptops).
  4. Disable Intel Turbo Boost or AMD Precision Boost.
  5. Save the settings (F10) and check the temperatures.
What is "repasting" and when is it needed?

Repasting is the replacement of thermal paste + thermal pads with complete disassembly of the laptop. Needed if:

- CPU/GPU temperature exceeds 95°C when idle.

- The laptop turns off due to overheating (thermal shutdown).

- The fans are running at maximum, but there is no cooling.

Cost at the service center: 1500–4000 rub. (depending on model).

FAQ: Frequently asked questions about laptop overheating

🔥 Why does the new laptop get hotter than the old one?

Modern processors (Intel 13th/14th generation, AMD Ryzen 7000) have high transistor density and TDP up to 125 W in game models. Manufacturers save on the cooling system by installing thin radiators and weak fans. For example, MacBook Pro M2 Max gets hot due to the compact body, and Lenovo Legion - due to aggressive GPU overclocking.

❄️ Is it possible to use a refrigerator or ice for cooling?

No! Sudden temperature changes lead to condensate inside the laptop, causing a short circuit. Ice can also damage plastic parts. The only exception is special cooling pad with Peltier elements, but they are expensive and ineffective.

🎮 Why does the laptop get hot in games, even if the FPS is low?

Video card (RTX 4060, RX 7600M) may overheat due to:

  • Poor game optimization (for example, Star Citizen or Warhammer 40K: Darktide).
  • High Power Limit (in MSI Afterburner install 80–90%).
  • GPU heatsinks clogged with dust (cleaning is required every 3 months for gaming laptops).
🔋 Does charging affect laptop overheating?

Yes! When running on mains power, the laptop consumes more power, which increases heat. 5–15°C. Tips:

  • Turn off charging when you reach 80% (use Battery Limiter in MyASUS or Lenovo Vantage).
  • Use the original power supply (cheap replacements heat up and reduce cooling efficiency).
  • B Windows set the power plan Balanced instead of High performance.
🛠️ Is it worth overclocking a laptop if it’s already overheating?

No! Overclocking (overclocking) increases the temperature by 15–30°C and shortens component life. Exception - undervolting (see section 5), which, on the contrary, reduces heating. If you want more performance:

  • Update BIOS (sometimes new versions improve fan control).
  • Use external GPU (For example, Razer Core X) for gaming/rendering.
  • Replace thermal paste with liquid metal (for advanced users only!).
