Thermal paste is an unnoticed but critical component of a laptop's cooling system. It ensures effective heat exchange between the processor, video card and heatsink, preventing overheating. Over time, the thermal interface dries out, loses its properties, and the temperature of the components begins to rise. But where exactly to look for this paste in the laptop case? The answer depends on the model, design and even year of manufacture of the device.

In this article we will figure out where the thermal paste is located in laptops of popular brands (ASUS, Lenovo, HP, Dell, Acer), how to detect it during disassembly, and what to pay attention to before replacing. You'll also learn what mistakes beginners make most often and how to avoid damaging components. If your laptop starts to get hotter than usual, this information will help you diagnose the problem and make the right decision.

Why is it important to know where the thermal paste is located in a laptop?

Thermal paste is not just a "lubricant" for the processor. It fills microscopic irregularities between the chip crystal and the surface of the heatsink, providing maximum contact area. Without it, the heat sink works 30–50% worse, which leads to:

  • 🔥 Throttling — automatic decrease in performance due to overheating.
  • 💥 Shutdowns under load (for example, in games or when rendering).
  • Increased wear of components, especially relevant for laptops with discrete graphics.
  • 🕒 Reduced battery life due to the constant operation of the cooler at maximum speed.

Many users mistakenly think that only “old” laptops need to replace thermal paste. In fact, even new devices (Lenovo Legion, ASUS ROG Zephyrus, MSI GS66) may require updating the thermal interface after 1–2 years of intensive use. Especially if the manufacturer saved on the quality of the paste.

⚠️ Attention: In some ultrabooks (for example, MacBook Air or Dell XPS 13) thermal paste is applied in a thin layer and can be almost invisible during disassembly. Do not confuse it with thermal pads - soft gray or black plates that are also used for heat dissipation.

Where to look for thermal paste: general principles of location

Regardless of the laptop model, thermal paste is always found between two key elements:

  1. Heat source - processor (CPU), graphics chip (GPU) or chipset.
  2. Cooling system - copper/aluminum heatsink plate or heat pipe (heat pipe).

To get to the thermal paste, you need to:

  1. Remove the bottom cover of the laptop (sometimes you need to remove the keyboard).
  2. Disconnect the battery (required!).
  3. Disconnect the cooler and radiator from the motherboard.

In most cases, the thermal paste will be visible immediately after removing the heatsink. It looks like a gray, white or silver layer between the chip and the metal plate. However, some laptops (especially gaming ones) may use liquid metal instead of a traditional paste, it has a characteristic shine and a more liquid consistency.

Component Typical thermal paste placement Notes
CPU (processor) Under the copper/aluminum heatsink plate, towards the center of the motherboard Often marked as Intel Core i5/i7/i9 or AMD Ryzen 5/7/9
GPU (video card) Under a separate section of the radiator, often closer to the left/right edge In laptops with NVIDIA or AMD Radeon there may be two zones with pasta
Chipset (PCH) Under a small metal plate, next to the processor Does not always require replacement of paste, but can get warm in office laptops
VRM modules Under or without thermal pads, next to the processor In gaming laptops (ASUS TUF, MSI GF63) may have separate cooling
📊 How often do you clean your laptop cooling system?
  • Once a year
  • Once every 2-3 years
  • Only when it starts to warm up
  • Never cleaned

Where is thermal paste located in laptops of different brands?

The design of laptops varies depending on the manufacturer. Let's look at the features of the location of thermal paste in popular models.

ASUS (ROG, TUF, ZenBook, Vivobook)

In game series (ROG Strix, ROG Zephyrus) thermal paste is usually located:

  • 🖥️ Under a massive radiator with 3-5 heat pipes (cools and CPU, and GPU).
  • 🔧 Often used liquid metal on the processor (for example, in ROG Zephyrus G14).
  • ⚠️ In ultrabooks (ZenBook) the heatsink can be soldered to the motherboard - disassembly requires experience.

In office models (Vivobook, X515) thermal paste is usually only on the processor, and the graphics chip (Intel Iris Xe) is cooled through a common radiator without separate paste.

Lenovo (Legion, ThinkPad, IdeaPad)

Laptops Lenovo known for their modular design:

  • 🎮 B Legion 5/7 thermal paste on CPU And GPU located under separate radiators with heat pipes.
  • 💼 B ThinkPad T/X-series The radiator is often secured with 4–6 screws, the paste is only on the processor.
  • 🔄 B IdeaPad 3/5 Cheap paste can be used, which dries in 1–1.5 years.

In laptops Lenovo Yoga with a rotating screen, the heatsink is often integrated into the case - replacing thermal paste requires complete disassembly, including removing the screen.

HP (Omen, Pavilion, Envy, Spectre)

HP often uses non-standard solutions:

  • 🎮 B Omen 15/16 thermal paste on CPU And GPU located under a common radiator with steam chambers.
  • 🖥️ B Pavilion Gaming There may be a separate paste on VRM modules (they get hot during overclocking).
  • ⚠️ B Spectre x360 The radiator is glued to the body - disassembly is risky without experience.

Dell (Alienware, XPS, Inspiron, G-series)

Dell known for reliable cooling systems, but with nuances:

  • 👽 B Alienware m15/m17 thermal paste on CPU And GPU located under massive radiators with heat pipes Vapor Chamber.
  • 💻 B XPS 13/15 paste only on the processor, graphics chip (Intel Iris Xe) is cooled passively.
  • 🔧 B Inspiron 15/16 Often there are problems with the paste drying out after 1.5–2 years.

Acer (Predator, Nitro, Swift, Aspire)

Acer uses standard cooling schemes:

  • 🎮 B Predator Helios/Triton thermal paste on CPU And GPU under separate radiators.
  • ⚡ B Nitro 5 There may be liquid metal on the processor (especially 2021+ models).
  • 💼 B Swift 3/5 CPU-only paste, often of low quality.
💡

Before disassembling the laptop Dell Alienware or ASUS ROG check if liquid metal is used. It cannot be cleaned with alcohol - only with special wipes!

How to find thermal paste yourself during disassembly

If you decide to replace the thermal paste yourself, follow this algorithm:

Turn off the power and remove the battery|Remove the bottom cover (a plastic spatula may be needed)|Take photos of the screw and cable locations|Disconnect the cooler and heatsink from the motherboard|Clean the old paste from the chips and heatsink-->

After removing the radiator you will see:

  • 🟢 Gray/white layer - traditional thermal paste (for example, Arctic MX-4, Noctua NT-H1).
  • 🟤 Silver glitter - liquid metal (Thermal Grizzly Conductonaut, Coollaboratory Liquid Ultra).
  • 🟣 Black/gray gaskets — thermal pads (not to be confused with paste!).

Pay attention to the condition of the old paste:

  • 🔴 Dry, cracked - requires urgent replacement.
  • 🟡 Liquid, spreading - Poor quality paste may have been used.
  • 🟢 Smooth layer without cracks — replacement is not necessary, but is recommended for prevention.
⚠️ Attention: In some laptops (MacBook Pro, Razer Blade) thermal paste can be covered with a protective film. Do not try to scrape it off - this is a factory coating and it is better not to damage it.
What to do if there is no thermal paste on the video card?

Some laptops (eg. Lenovo IdeaPad with graphics Intel UHD) the video card is cooled through a common radiator without separate paste. In this case, it is enough to replace the paste only on the processor. However, if you have discrete graphics (NVIDIA RTX or AMD Radeon), the absence of paste is a sign of incorrect assembly or manufacturing defect.

Typical mistakes when finding and replacing thermal paste

Even experienced users sometimes make mistakes that lead to poor cooling or damage to the laptop. Here are the most common:

  • 🔧 Using too thick a layer of paste - Excess may spill onto the motherboard and cause a short circuit.
  • 🧴 Using low quality paste (For example, KPT-8) - it dries in 3–6 months.
  • ⚠️ Forgetting to clean the old paste — remnants of the old thermal interface impair thermal conductivity.
  • 🔩 Incorrectly tightened radiator - too weak or strong fastening leads to poor contact.
  • 💻 Ignoring Thermal Pads - they also need to be replaced if they have lost their elasticity.

Another common mistake is incorrect disassembly order. For example, in laptops MSI or Gigabyte First you need to disconnect the battery, and only then remove the radiator. If you do the opposite, you can damage the cables or connectors.

Also, many people forget about testing after replacement. After assembling the laptop, be sure to:

  1. Check the temperatures in HWMonitor or AIDA64.
  2. Make sure the cooler operates without any extraneous noise.
  3. Run a stress test (Prime95 for CPU, FurMark for GPU).
💡

The optimal layer of thermal paste is thin and uniform. For a processor, a pea-sized amount is enough (≈0.1 g), for a video card - a little more (≈0.15–0.2 g).

When is it worth contacting the service, and when can you handle it yourself?

Replacing thermal paste is a task that most users can handle, but there are cases when it is better to trust the professionals:

Situation Can I do it myself? Recommendation
The laptop gets hot, but disassembly is standard (screws on the bottom cover) ✅ Yes Follow the instructions for your model, use a quality paste
Adhesive body (MacBook, Dell XPS) ❌ No (no experience) Risk of damage to cables or screen, it is better to contact service
Liquid metal is used ⚠️ Only if you have experience Requires special wipes and care when applying
Laptop under warranty ❌ No Self-disassembly will void the warranty.
After replacing the paste the temperature did not drop ⚠️ Possible, but diagnostics are needed The problem may be with the cooler, thermal pads or BIOS settings

If you decide to contact the service, choose trusted workshops. The cost of replacing thermal paste in Moscow or St. Petersburg varies from 1,500 to 4,000 rubles, depending on the complexity of disassembly. In the regions, prices are usually 20–30% lower.

When choosing a service, pay attention to:

  • 📝 Reviews - check Yandex.Maps or 2GIS.
  • 🔧 Guarantee — good workshops give a guarantee on work for 1–3 months.
  • 💰 Cost of spare parts — some services impose unnecessary services (for example, cleaning the keyboard).

FAQ: Frequently asked questions about thermal paste in laptops

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

The service life of thermal paste depends on its quality and operating conditions:

  • 🟢 High quality paste (Noctua NT-H2, Thermal Grizzly Kryonaut) - once every 2–3 years.
  • 🟡 Average quality (Arctic MX-4, Cooler Master MasterGel) - once every 1.5–2 years.
  • 🔴 Cheap/factory paste - once every 6–12 months (especially in gaming laptops).

Signs that it’s time to change the paste: constant operation of the cooler at high speeds, sudden shutdowns under load, processor temperatures above 90°C in games.

Can I use thermal paste from a computer for a laptop?

Yes, but with reservations:

  • ✅ Suitable pastes with low viscosity (For example, Arctic MX-6), which do not spread when the laptop is held vertically.
  • ❌ Not recommended thick pastes (KPT-8, AlSil-3) - they are distributed less well under radiator pressure.
  • ⚠️ For laptops with TDP above 45 W (gaming models), it is better to choose pastes with thermal conductivity from 10 W/mK.
What happens if you don't change the thermal paste?

The consequences depend on the degree of overheating:

  • 🔥 Short term: throttling (reduced performance), frequent shutdowns, cooler noise.
  • Medium term: battery degradation, failure of VRM modules.
  • 💥 Long term: detachment of the chip from the substrate (delidding), motherboard failure.

In extreme cases (for example, in laptops with NVIDIA GTX/RTX) overheating of the video card can lead to artifacts on the screen or complete GPU failure.

How to check if thermal paste needs to be replaced without disassembling?

The condition of thermal paste can be assessed by indirect signs:

  1. Use monitoring programs (HWInfo, Core Temp, GPU-Z) to check temperatures:
    • 🟢 Normal: up to 75–80°C under load.
    • 🟡 Limit: 85–90°C (throttling starts at ~95°C).
    • 🔴 Critical: above 95°C.
  2. Listen to the cooler:
    • If it constantly runs at high speeds even when idle, the paste has dried out.
  3. Check battery life:
    • Overheating reduces autonomy by 20–40%.

If the processor temperature rises to 100°C in a few seconds during a stress test, the thermal paste needs to be changed urgently.
