Laptop series HP Pavilion g6 have earned a reputation as reliable home and office assistants, but over time they face the inevitable problem of overheating. The main reason for poor performance and sudden shutdowns lies in the degradation of the thermal contact between the processor and the cooling system. Replacing thermal paste is a procedure that can restore the device to its former efficiency, reduce fan noise and prevent the failure of expensive components.
Many owners put off this manipulation for fear of difficult disassembly or damage to fragile cables. However, if you have a minimal set of tools and a clear understanding of the sequence of actions, the process takes no more than an hour. In this material we will analyze in detail how to properly dismantle the bottom cover, remove the radiator and apply a new heat-conducting compound to the CPU and GPU your device.
Before starting work, it is extremely important to prepare your work area and ensure that there is no static electricity. Incorrect actions can lead to a short circuit, so care and accuracy play a decisive role here.
Preparing tools and necessary materials
The success of the entire operation depends 90% on how well you prepared. You will need not only the thermal paste itself, but also a set of specialized tools to carefully disassemble the case. To work with series screws HP Pavilion g6 A set of Phillips-head screwdrivers is best, as screws can come in different sizes and shapes.
You will definitely need:
- 🛠️ Philips screwdriver No. 0 and No. 1 for unscrewing case and radiator screws
- 💉 High-quality thermal paste (for example, Arctic MX-4, Thermal Grizzly or original paste from HP)
- 🧴 Isopropyl alcohol and lint-free wipes for cleaning old composition
- 🧤 Anti-slip gloves and antistatic wrist strap (preferably)
Do not use household solvents or acetone for cleaning, as they can damage the plastic elements of the case or soften the insulation of the wires. Isopropyl alcohol is safe for electronics and evaporates quickly, leaving no residue.
You will also need a plastic card or a special mediator to carefully release the lid latches. It is not recommended to use metal objects to avoid scratching the case and shortening the contacts on the board.
Safe power off and housing removal
The first and most critical stage is to completely de-energize the device. Turn off the laptop, unplug the power adapter, and remove the battery. In the model HP Pavilion g6 The battery is usually secured with two latches that need to be moved towards the unlocking side.
After removing the battery, you must ensure that there is no residual charge left in the system. To do this, press the power button on the case and hold it for 15-20 seconds. This action will discharge the capacitors on the motherboard and reduce the risk of damage to components when touched.
Next, remove the bottom cover secured with screws. Please note that some screws may be hidden under rubber feet or stickers. After unscrewing all the fasteners, carefully run a plastic pick around the perimeter of the cover to release the latches.
After removing the cover, you will see the internal layout of the device. Before disconnecting any cables, make sure you know where and what is connected.
It's important to remember the location of the connectors if you plan to completely remove the motherboard, although replacing the paste often requires just access to the heatsink.
⚠️ Caution: Never pull on wires or cables to disconnect them. Always press down on the connector latch or gently pry it off with a plastic tool.
Removing the cooling system and cleaning components
To get to the processor and video card, you need to remove the metal radiator with copper heat pipes. The radiator is secured with screws, which are usually located in the order indicated by the arrows on the radiator itself or on the board.
Screws can be different lengths, so it is essential to remember or write down which screw goes where. Incorrect installation of screws can damage the threads on the board or cause uneven pressure on the heatsink.
The loosening process should be done slowly and one at a time, loosening each screw half a turn to release pressure evenly. Once all the screws are removed, carefully disconnect the power fan connector from the motherboard.
- 🔧 Unscrew the radiator screws strictly in the order indicated by the arrows (usually diagonally)
- 🔌 Disconnect the power fan connector by pulling the plastic connector
- 🧹 Gently lift the radiator without pulling sharply, so as not to damage the chips
After removing the heatsink, you will see an old, dried layer of thermal paste. It may be gray, cracked, or crumbly. This is exactly the material that stopped performing its function and caused overheating.
Cleaning the surface requires care. Use cotton swabs soaked in isopropyl alcohol to remove any old compound.
Clean the chips and radiator base until they are perfectly clean and shiny.

The process of applying new thermal paste and assembly
The application of new thermally conductive material is the moment of truth, which determines the effectiveness of cooling. There are several application methods, but for modern processors and video cards in laptops, the “dot” or “line” method is most often recommended.
For processor and video card in HP Pavilion g6 It is better to apply a small amount of paste to the center of the chip. Under the pressure of the radiator, the paste itself will spread evenly over the entire surface, filling micro-irregularities.
Too much thermal paste is just as harmful as too little. If you apply too much, it can leak off the chip and onto nearby components, causing a short circuit.
Use a pea-sized drop or a thin line in the center. Do not try to smear it with your finger or spatula by hand, as this may disrupt the uniformity of the layer.
☑️ Preparation for application
Important nuances of installing a radiator and fan
After applying the paste, you must carefully put the radiator back in place. It is important not to move the chip or heatsink to the side so that the paste layer remains uniform. Carefully lower the heatsink, aligning the screw holes with the threads on the board.
Tightening the screws must be done strictly in the reverse order from dismantling, usually diagonally. This ensures uniform pressure of the radiator against the chips and eliminates distortion.
- 🔄Tighten the screws gradually, one at a time, until completely tightened
- 🔊 Check that the fan does not touch the wires or housing
- 🔌 Connect the power fan connector until it clicks
It is recommended to conduct a test run before fully assembling the case. Connect the power, but leave the bottom cover off yet, and turn on the laptop. Make sure the fan is spinning and the system does not display overheating errors immediately after startup.
If the fan is noisy or does not spin, turn off the device immediately and check the connector connections.
Only after making sure that the cooling system is working can you close the case and tighten all the screws.
| Component | Old condition | Recommended Action | Note |
|---|---|---|---|
| Processor (CPU) | Dried, gray mass | Complete cleaning and application of new paste | Temperature critical |
| Video card (GPU) | Cracked layer | Cleaning with alcohol and new paste | CPU often gets hotter |
| Radiator | Dust in the ribs | Blowing with compressed air | Improves heat dissipation |
| Fan | Noise, backlash | Bearing lubrication or replacement | Important for air flow |
Result testing and prevention
After assembly, the laptop is ready for use. However, to ensure the effectiveness of the work done, it is worth conducting a stress test. Use special utilities such as AIDA64 or Cinebenchto load the processor and video card.
Monitor temperature readings at idle and under load. For model HP Pavilion g6 Temperature is considered normal when idle 35-45°C, and under load - 65-80°C. If the readings are higher, the problem may be not only with the thermal paste, but also with a dust-clogged heatsink.
What to do if the temperature has not dropped?
If after replacing the paste the temperatures remain high, check: 1. Is the radiator installed correctly (is there any misalignment). 2. Is the radiator clogged with dust (full cleaning of the channels may be required). 3. Is the fan running at full power (the bearing may have failed). 4. Are the thermal pads on the VRAM memory chips dry?
Regular preventive maintenance will help avoid recurrent overheating. Check the cleanliness of the cooling system every 6-12 months.
Use a stand with fans for extra cooling during intense work.
⚠️ Warning: Do not use the vacuum cleaner at maximum power to clean the radiator, as static electricity may damage the electronic components. It is better to use a can of compressed air.
Common mistakes when replacing thermal paste
Even experienced users can make mistakes that ruin all their efforts. One of the most common problems is using too much thermal paste. Excess material may leak out and get onto the contacts, causing short circuits or corrosion.
Another common mistake is using low-quality paste. Cheap compounds, often included with processors, quickly dry out and lose their properties. Choose proven brands with high thermal conductivity.
Do not forget about the importance of cleaning not only the chips, but also the radiator base itself.
Ignoring dust in the ventilation ducts can also lead to rapid overheating even with new paste.
Store the old thermal paste in an airtight container if you plan to sell the laptop or give it away to someone else, so the new owner knows that a replacement has already been made.
Conclusion and final recommendations
Replacing thermal paste with HP Pavilion g6 is an effective way to extend the life of your laptop and restore its performance. A correctly performed procedure reduces temperatures by 10-20 degrees, which has a positive effect on the stability of the system.
Remember that accuracy and consistency are more important than speed. If you doubt your abilities, it is better to entrust the work to professionals, but if you follow the instructions, you can do it yourself.
Regular maintenance of the cooling system is the key to long and trouble-free operation of your device.
Do not ignore overheating signals and carry out preventive maintenance in a timely manner.
The most important rule: always turn off the power and remove the battery before disassembling your laptop to avoid permanent damage to the electronics.
