Laptop overheating is one of the most common problems that equipment owners face. HP after 2-3 years of operation. The cause is most often dried out or degraded thermal paste — a special composition that ensures heat transfer between the processor/chipset and the cooling system. If your HP Pavilion, Omen, Envy or ProBook started to suddenly turn off, slow down under load, or make loud cooler noise - it’s time to think about replacing the thermal interface.

In this article we will analyze the entire process from A to Z: how to choose the right thermal paste, disassemble the laptop without damage, clean the old layer and apply a new one. We will pay special attention HP models with a soldered cooling system (for example, HP Spectre x360 or EliteBook), where care is required when dismantling the radiator. You will also learn how to check the result of the work and avoid common mistakes that lead to repeated overheating.

Signs that it's time to change the thermal paste

Laptops HP often suffer from overheating due to compact cases and weak cooling systems. Here are the key symptoms indicating the need to replace the thermal interface:

  • 🔥 Spontaneous shutdowns when gaming, rendering or long-term work - overheating protection is triggered at temperatures higher 95-100°C.
  • 💨 Constant operation of the cooler at maximum, even in idle mode (for example, in Google Chrome with 5-10 tabs).
  • 🐢 Performance drawdowns — the laptop begins to “slow down” due to throttling (automatic reduction of processor frequencies).
  • 🌡️ Hot case in the keyboard area or below, especially on the left (where the processor is usually located).

If you observe at least 2-3 signs from the list, the probability of a problem with thermal paste is 80-90%. However, before disassembling it is worth ruling out other causes: dust contamination, cooler malfunction or BIOS restrictions. For diagnostics, use programs like HWMonitor, Core Temp or ThrottleStop - they will show the current temperatures and frequencies.

⚠️ Attention: On some models HP (For example, HP Pavilion Gaming 15) overheating may be due to a defect in the thermal pads on the chipset or video card. If after replacing the paste the processor temperature has returned to normal, but the GPU is still heating up, the gaskets will need to be replaced.

Which thermal paste to choose for an HP laptop

The choice of thermal interface depends on the laptop model and its heat dissipation. For office HP ProBook or EliteBook budget options are suitable, and for gaming HP Omen or Pavilion Gaming High-performance compounds are needed. Here is a comparison table of popular thermal pastes:

Thermal paste model Thermal conductivity (W/mK) Service life Recommendations
Arctic MX-6 11.0 8+ years Universal choice for most laptops HP. Does not conduct electricity, easy to apply.
Noctua NT-H2 8.5 5-6 years Good for office models. The set includes a spatula and napkins.
Thermal Grizzly Kryonaut 12.5 3-4 years For gaming laptops (HP Omen 16, Victus). Requires replacement more often due to drying out.
Coollaboratory Liquid Ultra 38.4 1-2 years An extreme option for overclocking. Requires experience - liquid metal conducts electricity!

For most users, the optimal choice will be Arctic MX-6 or Noctua NT-H2. They provide a good balance between price, thermal conductivity and durability. If you are overclocking or have a top gaming model (for example, HP Omen 17 with RTX 4070), can be considered Thermal Grizzly Kryonaut or even liquid metal - but only if the contacts are insulated!

⚠️ Attention: Never use cheap thermal pastes from unknown brands (for example, "KPT-8"). They often contain silicone, which turns into a hard crust over time and impairs heat transfer. Also avoid pastes with abrasive particles - they can damage the processor cover.
💡

Before purchasing, check to see if the thermal paste has expired. Old compounds lose their properties even in the original packaging.

Preparing for replacement: tools and safety precautions

To replace thermal paste on a laptop HP, you will need:

  • ⚒️ Screwdriver set (cross PH00, sometimes T5 or T6 for some models).
  • 🧴 Thermal paste (selected from the table above) and thermal pads (if replacement is required).
  • 🧹 Lint-free wipes And isopropyl alcohol (90%+) for cleaning.
  • 🔍 Plastic card or mediator to gently lift the lid.
  • 📸 Smartphone - to photograph the disassembly process (useful during assembly!).

Also prepare your work area: a table with good lighting, an antistatic mat (or at least a non-synthetic fabric), containers for screws. Unplug your laptop, remove the battery (if it is removable) and ground yourself by touching a metal object - this will protect the components from static electricity.

If you have a model with a soldered battery (for example, HP Spectre x360 13), disabling it will require caution. Usually it is enough to disconnect the cable from the motherboard, but on some devices you will have to work with Battery Connector - a small connector that is easy to damage. In this case, it is better to use plastic tweezers.

Step-by-step disassembly of an HP laptop

The disassembly process depends on the model, but the general procedure is the same for most laptops HP. Let's consider a universal algorithm using an example HP Pavilion 15:

  1. Turn the laptop over and remove all the screws on the bottom cover. Please note: Some screws may be hidden under rubber feet or stickers.

  2. Carefully pry the lid open with a plastic card, starting from the corner. On models HP Envy or Spectre The cover can be secured with latches - do not use excessive force!

  3. Disconnect the battery cable (if it is non-removable). On some laptops (HP Omen 16) the battery may be glued, in which case heating with a hairdryer will be required.

  4. Unscrew the screws securing the cooling system. They are usually marked with arrows or numbers - remember the tightening order!

  5. Remove the radiator. If the thermal paste “sticks”, do not pull it - gently twist the radiator from side to side.

When removing the radiator, be careful: on some models HP (For example, HP EliteBook 840 G7) heat pipes can be rigidly fixed. If you feel resistance, do not pull by force, but check that all screws are unscrewed. Also pay attention to the thermal pads: if they have delaminated or hardened, they also need to be replaced.

What to do if the screw “doesn’t work”?

If a screw is too tight or has damaged threads, do not force it out. Use a rubber band: place it on the head of the screw and try to unscrew it with a screwdriver - this will increase the grip. If it doesn't help, contact service.

After removing the heatsink you will see the processor and (possibly) chipset/video card. At this stage do not touch the contacts on the motherboard and do not drop foreign objects onto it. It’s better to immediately photograph the location of all components - this will help with reassembly.

Cleaning old thermal paste and applying new one

Removing the old thermal interface is one of the most critical steps. Here's how to do it right:

  1. Dampen a lint-free cloth isopropyl alcohol (90% or higher) and gently wipe the surface of the processor and heatsink. Do not use cotton swabs - they may leave lint!

  2. For hardened paste residue, use a plastic card or wooden stick. Never scratch the processor cover with metal objects!

  3. Allow surfaces to dry completely (2-3 minutes). Check that there are no alcohol stains left.

Now we move on to applying new thermal paste. There are several nuances here:

  • 🎨 Quantity: for most processors Intel (For example, i5-1135G7 in HP Envy x360) a pea-sized drop (4-5 mm) is enough. For AMD Ryzen (For example, Ryzen 7 5800H in HP Omen) - a little more, since they have a large lid.
  • 🔄 Application method: for laptops it is better to use the “cross” or “line” method - this way the paste will be distributed more evenly under the pressure of the radiator.
  • ⚠️ Avoid excess: Too much paste can leak onto board components and cause a short circuit (especially dangerous for liquid metal!).

After applying the paste, carefully install the radiator back and tighten the screws crosswiseto ensure even pressure. Do not tighten them too tightly, as this may distort the motherboard. The optimal force is when the screw begins to “resist” but does not “creak”.

💡

On HP laptops with dual-channel cooling (for example, HP Pavilion Gaming 16) first tighten the screws closer to the center, then along the edges. This prevents the radiator from skewing.

Assembling the laptop and turning it on for the first time

Assembly occurs in the reverse order, but there are several critical points:

  • 🔌 Loops: Make sure all cables (battery, touchpad, keyboard) are connected tightly. On models HP Spectre cables are often secured with latches - check that they snap into place.
  • 🔩 Screws: Use photographs taken during disassembly. The screws are of different lengths - if you mix them up, you can damage the board.
  • 🖥️ First startNote: After assembly, do not turn on the laptop immediately. Wait 5-10 minutes for the thermal paste to settle, then connect the charger and start the device.

When you turn it on for the first time, pay attention to the following points:

  • The cooler should start and stop briefly (this is normal).
  • If the laptop does not turn on, check the battery and RAM connections.
  • If the cooler operates at maximum without load, the radiator may be poorly pressed (check the screws).

After a successful launch, install a temperature monitoring program (for example, HWInfo) and check the indicators:

  • In idle mode: 30-45°C (the norm for most processors).
  • Under load (stress test in AIDA64 or Prime95): up to 85-90°C (if higher, perhaps there is not enough paste or the radiator does not fit well).
⚠️ Attention: On some laptops HP (For example, HP EliteBook 850 G8) after replacing the thermal paste, the “tamper-evident” protection may work. In this case, when turned on, a message will appear "Security Tamper Detected". To reset it, go to BIOS (F10 at boot) and select Clear Tamper Event.

Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when replacing thermal paste. Here are the most common ones and ways to prevent them:

Error Consequences How to avoid
Using too much paste Leakage onto board components, short circuit Apply pea-sized drops, even smaller for liquid metal
Uneven tightening of radiator screws Misalignment, poor contact, high temperatures Tighten the screws crosswise in 2-3 steps
Cleaning with low concentration alcohol (<70%) Remains of fat on the surface, deterioration of heat transfer Use 90% isopropyl alcohol or higher
Forgot to disconnect the battery before disassembling Short circuit, motherboard failure Always disconnect the battery, even if the laptop is turned off

Another typical problem is ignoring thermal pads. On many laptops HP (For example, HP Pavilion Gaming 15) spacers are used to cool the chipset, MOSFET transistors or video memory. If they have dried out or lost their elasticity, they definitely needs to be replaced for new ones (for example, Thermal Grizzly Minus Pad 8 thickness 1-1.5 mm).

Also don't forget about cleaning the cooling system. Dust in the radiator can negate the effect of new thermal paste. Use a can of compressed air or a soft brush, but not a vacuum cleaner - it creates static electricity!

FAQ: answers to frequently asked questions

Is it possible to replace thermal paste on an HP laptop without disassembling it?

No, it is impossible to replace thermal paste without completely disassembling it. The thermal interface is placed between the processor and the heatsink, and access to them requires removal of the cooling system. The only exception is laptops with direct access to the cooler (for example, some models HP ZBook), but even in this case you will have to remove the bottom cover.

How often should you change the thermal paste on an HP laptop?

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

  • Budget pastes (for example, Arctic MX-4) - once every 2-3 years.
  • Premium compounds (Noctua NT-H2, Thermal Grizzly Kryonaut) - once every 4-5 years.
  • Liquid metal (Coollaboratory Liquid Ultra) - once every 1-2 years (due to oxidation).

If the laptop is used in a dusty room or often works under high load (games, rendering), the replacement interval is reduced.

What should I do if my laptop gets hotter after replacing the thermal paste?

If temperatures increase, check the following:

  1. Correct application of paste (perhaps too little or too much).
  2. The tightness of the radiator (the screws may have been tightened unevenly).
  3. Condition of thermal pads (if they are delaminated, they need to be replaced).
  4. Cooler operation (perhaps the cable is not connected or the blades are blocked).

Also run the test in AIDA64 and check if throttling (reducing frequencies) is working. If the problem persists, return to the old thermal interface and repeat the procedure.

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

Yes, thermal pastes are universal - the same Arctic MX-6 or Noctua NT-H2 Suitable for both desktops and laptops. However, for laptops it is more important durability (since it is often more difficult to disassemble them) and no spreadability (in a compact case, paste may get on the components). Avoid cheap compounds with silicone - they dry out faster.

Does the thermal paste need to be changed on a new HP model (such as the 2023 Omen 16)?

On new laptops, there is no need to change the thermal paste - the manufacturer applies a high-quality compound designed to last 3-5 years. However there are exceptions:

  • If you are buying a laptop used and you don't know its history.
  • If you plan acceleration (for example, on HP Omen with RTX 4080).
  • If the laptop was used in a hot climate or under constant load.

In these cases, you can replace the paste with a more productive one (for example, Thermal Grizzly Kryonaut) to improve cooling.
