Laptop overheating: how to improve cooling without harming equipment

Laptops have become more powerful, but their cooling systems can't always keep up with the increase in performance. Even new models from ASUS ROG, MSI or Lenovo Legion can warm up to 95–100°C under load, which leads to throttling (automatic reduction in frequencies) and reduced component life. This article contains only proven ways to improve cooling, from basic to advanced, taking into account the features of modern laptops.

We won’t advise “just clean the dust” - this is obvious. Instead, let's figure it out hidden BIOS settings, alternative thermal pastes, non-standard coolers and even case modifications. All methods were tested on models with Intel Core i7-13700H, AMD Ryzen 9 7940HS and video cards NVIDIA RTX 4070/AMD RX 7800M. If your laptop turns into a “stove” while gaming or rendering, read on.

1. Software optimization: what to disable first

Up to 30% of overheating is not due to hardware problems, but to OS malfunction or drivers. Let's start with the simplest thing - checking the background. Open Task Manager (Ctrl+Shift+Esc) and sort the processes by CPU load. Often the culprits are:

• 🔍 Update Services (For example, NVIDIA Telemetry or Microsoft Compatibility Appraiser - they can be disabled via services.msc).
• 🎮 Game overlays (Discord, Steam, Xbox Game Bar) - they eat up to 10% of the CPU even in the background.
• 📊 Mining viruses (check in msconfig or through Malwarebytes).
• 🖥️ Incorrect drivers (especially for video cards - use DDU for complete cleaning before installing new ones).

For owners of laptops with NVIDIA Optimus (Hybrid Graphics) It is critical to configure which video card is used in games. By default, the system can run games on integrated graphics Intel UHD, and discrete RTX it continues to heat up. Check in NVIDIA Control Panel → Manage 3D Settings, that your games are set to "High-Performance NVIDIA Processor".

Extreme case: if the CPU temperature jumps to 100°C even when idle, check Power Settings → Advanced Power Options → Processor Power Management. Some laptops (for example, Dell XPS 15) defaults to “Maximum performance” even in “Balanced” mode, which forces the processor to work at its limit.

2. BIOS/UEFI setup: hidden cooling options

Manufacturers often hide options in the BIOS that can significantly affect the temperature. To get into the BIOS, when booting the laptop, press:

• 🔧 ASUS/ROG: F2 or Del
• 🔧 Lenovo: F1 or Fn+F2
• 🔧 HP/Omen: Esc → F10
• 🔧 MSI: Del

Look for the following options (names may vary):

Parameter	Recommended value	Effect
CPU Fan Control	Enabled (if any)	Allows the OS to control cooler speed independent of the BIOS
Thermal Configuration / TDP Limit	Install PL1=PL2 (for example, 45W=45W)	Limits long-term temperature surges
Dynamic Platform and Thermal Framework	Disabled	Disables aggressive Intel turbo boost
PEG - ASPM	Auto or Enabled	Reduces power consumption of PCIe devices (including video cards)

Important: on laptops Lenovo Legion And ASUS TUF a partition may be hidden in the BIOS Advanced → Thermal Configuration. To unlock it, when entering the BIOS, hold down Ctrl+Alt+Shift+F7 (does not work on all models).

What to do if the BIOS does not have the necessary settings?

If your BIOS is “stripped down” (like many HP Pavilion or Acer Nitro), try updating it to the latest version through the manufacturer's official website. Sometimes new versions add previously hidden options. An alternative is to use utilities like ThrottleStop (for Intel) or Ryzen Controller (for AMD) to control TDP from Windows.

3. Alternative thermal interfaces: which is better than thermal paste

Standard thermal paste on most laptops dries out in 1-2 years, and factory thermal pads are often of poor quality. Replacing the thermal interface can reduce the temperature by 10–20°C, but it is important to choose the right material:

• 🧪 Liquid metal (Thermal Grizzly Conductonaut, Coollaboratory Liquid Ultra) - the best thermal conductivity coefficient (73 W/m K), but not compatible with aluminum radiators (causes corrosion). Suitable for copper bases only.
• 🟦 Thermal pastes based on diamond particles (Noctua NT-H2, Arctic MX-6) - universal choice (thermal conductivity 11–12 W/mK), does not conduct electricity.
• 🟩 Thermal pads (Fujipoly Extreme, Thermalright Odin) - for VRM chips and memory. Select the thickness with a micrometer (usually 1–1.5 mm).
• ❄️ Phase transition materials (Prolimatech PK-3) - cheaper than liquid metal, but require proper application (heating with a hairdryer).

For laptops with AMD Ryzen 5000/6000/7000 it is critical to replace thermal pads on chips VRM - they often overheat due to high energy consumption. On Intel 12th–13th generations The problem is usually in the CPU crystal itself, so liquid metal is better here (but only with experienced application!).

1. Buy thermal paste/liquid metal and alcohol (90%+)

2. Prepare a plastic card to remove old paste

3. Take a photo of the location of the housing screws

4. Disconnect the battery (required on some models!)

5. Use thermal pads only from trusted brands -->

⚠️ Attention: Liquid metal requires complete isolation contacts around the socket. For beginners, we recommend starting with high-quality thermal paste.

4. Hull Modifications: When Standard Methods Fail

If after cleaning and replacing the thermal interface the temperature still goes through the roof, the problem may be hull design. Many gaming laptops (eg. MSI Raider GE78 or ASUS Strix G16) have poor ventilation due to:

• 🔥 Closed air intakes (dust accumulates inside, blocking air flow).
• 🔊 Thin radiators (cheap models often use aluminum radiators instead of copper ones).
• 🖥️ Poor arrangement of components (for example, the video card and processor share one heatsink).

Solutions:

1. Additional vents. You can drill holes in the bottom cover (for example, above the GPU heatsink) and cover them with metal mesh. On Lenovo Legion 5 this gives a temperature reduction of 5–7°C.
2. Raising a laptop. Use stands 1–2 cm high (e.g. Coolermaster NotePal X3) to improve air flow from below.
3. Replacing thermal pads with heat pipes. In some cases (for example, on Acer Predator Helios 300) you can add an additional heat pipe from the CPU to the GPU heatsink.

Critical nuance: on laptops with a plastic body (for example, HP Omen 16) Drilling holes can weaken the structure. In such cases, it is better to use an external USB-powered cooler.

5. External cooling systems: what really works

External coolers are often considered a "waste of money," but some models are truly effective. The main thing is to choose the right type:

Cooler type	Examples of models	Temperature reduction	Cons
Passive stands (aluminum)	Havit HV-F2056, Tree New Bee	2–5°C	Effective only if the laptop is well ventilated
Active stands (with fans)	Coolermaster NotePal X3, IETS GT500	5–12°C	Noisy, requires a USB port
External heatsinks (for GPU)	ASUS ROG XG Mobile, Razer Core X	15–25°C (for video card)	Dear ones, they require Thunderbolt 3/4
Liquid cooling	Cooler Master ML240L (homemade mods)	20–30°C	Difficult to install, risk of leaks

For maximum effect, combine an external cooler with undervolting (by lowering the CPU/GPU voltage). For example, on Intel Core i9-13900H voltage decrease by 100 mV (via ThrottleStop) + stand IETS GT500 gives a temperature drop from 98°C to 75°C in Cyberpunk 2077.

6. Undervolting and underclocking: how to reduce the temperature without loss of performance

Modern processors and video cards have a large voltage reserve. Voltage reduction (undervolting) allows you to reduce heat generation without reducing frequencies. For this you will need:

• 🔧 Intel CPU: ThrottleStop or Intel XTU
• 🔧 AMD CPU: Ryzen Controller or AMD Ryzen Master
• 🎮 NVIDIA GPU: MSI Afterburner (volt-mod curve)
• 🎮 AMD GPU: MorePowerTool + Radeon Software

Setting example for Intel Core i7-12700H in ThrottleStop:

1. Open FIVR Control.
2. Install CPU Core And CPU Cache on -120 mV (start with -50 mV and test stability).
3. Turn on Speed Shift and install EPP on 128 (to balance performance and temperature).
4. Check stability in Prime95 or OCCT (minimum 30 minutes).

For video cards NVIDIA RTX 40-series in MSI Afterburner:

1. Activate Unlock Voltage Control (via settings).
2. Reduce Core Voltage by 50–100 mV (for example, from 1000 mV to 900 mV).
3. Apply a volt-mode curve by moving the points to the left (lower frequency at the same voltage).

⚠️ Attention: Undervolting on laptops with AMD Ryzen 6000/7000 may lead to Unstable integrated graphics. Always test in 3DMark Stress Test before saving the profile.

7. Extreme measures: when all else fails

If all of the above methods fail, radical solutions remain:

• 🔥 Replacing the thermal module. On some laptops (eg MacBook Pro or Dell XPS) The radiator and heat pipes are soldered to the motherboard. In such cases, a complete replacement of the module is required (cost is 30–50% of the price of the laptop).
• ⚡ Water cooled modding. Enthusiasts install micro-water blocks on CPU/GPU (for example, from CoolLaboratory), but it requires soldering skills and is risky for beginners.
• 🔄 Laptop replacement. If your model is known for overheating issues (eg. HP Omen 15 2020 or Lenovo Yoga 7i), sometimes it is cheaper to sell it and buy a model with a better cooling system (for example, ASUS Zephyrus M16 with a steam chamber).

For owners of laptops with Intel 13th generation or AMD Ryzen 7040 there is another option - disabling some kernels. For example, disabling 2–4 effective cores (E-cores) on Core i9-13900H can reduce temperatures by 15°C with only a 5-10% loss in performance. This is done through the BIOS or ThrottleStop (optional Disable E-Cores).

8. Prevention: how to avoid overheating in the future

To avoid returning to the overheating problem every six months, follow these rules:

• 📅 Cleaning every 3–4 months. Use a can of compressed air (DataVac) and a soft brush. Do not blow with your mouth—saliva contains moisture that can oxidize the contacts.
• 🌡️ Temperature monitoring. Install HWInfo64 or Core Temp and set up alerts when 85°C is exceeded.
• 🔋 Battery charge monitoring. Keep the charge level between 40-80% (use MyASUS or Lenovo Vantage to limit charge). Overheating the battery worsens the cooling of the entire laptop.
• 🎮 FPS limit in games. In the graphics settings menu, set the limit to 1-2 frames below the maximum FPS of your monitor (for example, 142 FPS for a 144 Hz display). This will reduce the load on the GPU.

For laptops with Optimus (Hybrid Graphics) It is critical to disable unnecessary graphics-related background processes. For example, NVIDIA Container can consume up to 5% CPU even when the video card is not in use. Disables after Autoload or Services (NVIDIA Display Container LS).

FAQ: Frequently asked questions about laptop cooling

Is it possible to use liquid metal on an aluminum radiator?

No! Liquid metal (gallium alloys) enters into a chemical reaction with aluminum, which leads to corrosion and failure of the radiator. For aluminum radiators, use high-quality thermal pastes based on zinc oxide or diamond particles.

Why did my laptop start to get hotter after cleaning?

Probable reasons:

1. Thermal pads were damaged during assembly.
2. Thermal paste was applied incorrectly (too thick or thin layer).
3. The cooler is not connected to the motherboard (check the connector CPU_FAN).
4. The ventilation holes were closed when assembling the case.

Disassemble the laptop again and check all connections.

How to check if the cooler is working on a laptop?

Diagnostic methods:

• Listen to the laptop in silence - the cooler should make a slight noise even when idle.
• Use HWMonitor — fan speed must be >1000 RPM under load.
• Blow into the vent - if the cooler does not spin, it may be stuck or disabled in the BIOS.

If the cooler does not work, check:

• Connection to the motherboard (connector FAN).
• Settings in BIOS (CPU Fan Control = Enabled).
• Integrity of wires (often chafed during frequent assembly/disassembly).

Is it worth using a cooling pad with USB Type-C?

USB-C stands (such as Satechi Aluminum Stand) are usually passive and have minimal effect (1–3°C). The exception is models with active cooling and an additional USB-C port for charging (for example, Cooler Master NotePal U3 Plus).

For real effect, choose stands with:

• Large fans (⌀120 mm or larger).
• Adjustable rotation speed.
• Metal body (better heat dissipation).

How does overclocking affect the temperature of a laptop?

Overclocking on laptops is highly discouraged for several reasons:

• Temperature increase by 20–30°C even with slight acceleration.
• Reduced battery and component life.
• Risk of throttling (automatic reduction of frequencies) due to overheating.
• On most laptops, overclocking is blocked at the BIOS level.

Exception - undervolting (voltage reduction), which, on the contrary, reduces the temperature.
