Can I Use Vaseline As A Thermal Paste?

Thermal paste is frequently unavailable to assemblers and computer repairers. It is essential because it lowers the thermal resistance between the CPU and the heat sink, allowing the CPU to run cooler. Today, Can I Use Vaseline As A Thermal Paste? Is the topic of this article. Vaseline is a readily available and affordable material.

Even though many people are unaware of its value, thermal paste is crucial. Computer builders frequently overlook it when placing the heatsink directly on the CPU. The main objective of thermal paste is to facilitate heat transfer from the CPU (or other chips) to the heatsink.

Even though the two parts are in close contact, air bubbles would form and restrict the flow of heat without the thermal paste. You shouldn’t give up if you don’t find any thermal paste. There are numerous effective, affordable, and accessible alternatives to remedy the issue temporarily.

The purpose of the thermal paste is to fill in the minute flaws of the surfaces coming into contact, which unavoidably traps air particles. The CPU does not cool down effectively since air is a poor heat conductor.

Can I Use Vaseline As A Thermal Paste?

Vaseline oil and extremely fine aluminum powder can be combined to create another product that can be used as a thermal paste. To prevent tiny air bubbles, the mixture must be mixed for at least 10 minutes.

Thermal Paste

A dense compound called thermal paste increases thermal contact between heat sinks and electronic components. Due to their extreme inefficiency and high energy loss in the form of waste heat, CPUs must use it. This paste often contains silicone and zinc oxide and has a high thermal conductivity. Higher thermal conductivity liquid metal products are also available.

The primary requirement is to disperse CPU heat and transfer it through the metal heatsink to the ambient air. For this to work, a minimum thermal resistance must exist between the CPU and the heatsink.

Cocoa And Hazelnut Cream

Due to their delicate consistency, cocoa and hazelnut spreads are perfect for creating a reliable thermal paste. Please do not use them for longer than two to three days. Some 15-minute “load” testing has revealed that these pastes perform well. The processor’s temperature remained low during operation (in “under load” mode, it was around 40° C; in idle mode, it was around 31° C).

In Emergencies

The major function of thermal paste is to create a thermal connection between the heat sink and the CPU (or other integrated and power circuits). The distances between the two faces are inevitably quite narrow.

They are not empty but rather filled with air, which conducts heat poorly. The heatsink’s efforts are futile if there are air bubbles present. The micro-imperfections must be filled with thermal paste to get rid of these air bubbles.

It can be swapped out if necessary with different greasy materials conveniently available at home. The offered remedies are valid for a few hours or days; it is crucial to note. Applying the commercial thermal paste as soon as feasible is therefore important.

Alternative products have a very short decay time; after a few hours of use, they may evaporate and stop working as intended. Let’s examine some other intriguing cases.

Building a thermal device that replicates the CPU temperature using a heated plate and a sufficient heat sink would be a good idea for people who want to pursue further studies. Sensors or a thermal camera could be used to measure the temperatures.

Diaper Rash Cream

The primary ingredient in commercial thermal paste, zinc oxide, is abundant in this kind of cream. On the heat sink, you can apply a thin layer, which will function flawlessly for 5–6 months. Use alcohol to clean the CPU surface before applying the new paste gently.

Other Solutions

A chemistry enthusiast could devise a decent method to create an emergency thermal paste because there are countless experimental possibilities. Some other concepts might be tested, perhaps on a dated CPU.

It should be remembered that some materials can only withstand extremely high temperatures for a relatively limited period, leading to their rapid deterioration. The following goods can be examined either separately or in combination:

  • American Cheese
  • Banana
  • Hair Wax
  • Moisturizing Cream
  • Adhesive For Dental Prostheses
  • Yellow Cheese
  • Butter
  • Card
  • Cheese Spread

Although mustard and ketchup also have a very intriguing thermal coefficient, they deteriorate after 24 to 48 hours. Although they melt in a short while, butter and moisturizer are also great short-term fixes. The motherboard and the nearby electronic circuitry could also be at risk from the oil spilling onto the circuits.

Does Salty Toothpaste Differ From Regular?

Being straightforward. Alkaline bases are among the basic components of every toothpaste. This is required to balance the acidic environment in our mouths. The bacteria in our mouths break down food particles, sugars, and carbohydrates into organic compounds, making our mouths acidic.

The alkaline base is now known to be the main component of any toothpaste, but there are also flavoring additives like mint, salt, essential oils, and others. So we particularly discuss salt among them. Therefore, there are certain differences between toothpaste that contain salt and those that do not.

Salt gives the sol additional basicity. Due to its rough surface, toothpaste and water. It aids in improved tooth cleaning and gives off a fresh odor. As though most toothpaste manufacturers also incorporate fluoride or fluoride ions into their toothpaste to protect our teeth from early decay.

The cleaning industry uses fluorine frequently, and even a small amount of it is healthy for us. You would be correct to assume that chlorine is utilized extensively in the cleaning industry. For example, chlorine is employed in water purification.

However, since it poisons us with chlorine and is lethal, we can’t apply it directly to our bodies or teeth. But the matter is still up for debate. Do you require toothpaste? My response is “no.” For brushing, you can mix baking soda and salt or use charcoal. And occasionally, this trick is more effective than toothpaste.


There are a lot of thermal paste substitutes available online. The CPU warranty is revoked through homemade means. Since a commercial thermal paste tube costs less than $10 and is adequate for many situations, there is no need to burn the microprocessor. However, an adequate cooling system is always the key to success.

If not, a better and more effective heat sink must be added. A strong, continuous airflow is necessary to ensure the components’ ventilation. Toothpaste or hair wax might be used as temporary fixes in urgent emergencies. I’ve mentioned everything about Can I Use Vaseline As A Thermal Paste??\

When it’s time to use the real thermal paste, you need to use a utility knife to cut away the old dried compound, rub cotton and alcohol on the two contact surfaces, and then wipe away any extra extracts.

The real commercial thermal paste must occasionally be reapplied because it dries up. On a cheap, outdated PC, you can experiment with these strategies. For a few days, they can guarantee independence and effective dissipation.

In any event, the new motherboards and CPUs have sufficient over-temperature safeguards, allowing the system to stop an unexpected situation by shutting down the circuits promptly. Finally, the above procedures are not advised for individuals who enjoy CPU overclocking.

Frequently Asked Questions

Does Vaseline act as a thermal conductor?

Because petroleum jelly has a low thermal conductivity and acts as insulation [4], it is combined with 10% aluminum powder to boost thermal conductivity, ultimately forming the desired PCM.

Is toothpaste a suitable thermal paste?

Even if toothpaste doesn’t have known heat conductivity, it might still be preferable to nothing. You should also take into account what the toothpaste components might do if they come into touch with your CPU.

Can my computer function without thermal paste?

Your entire system will overheat if you don’t apply thermal paste because it will produce more heat than it is built to handle. The CPU is one of the essential parts of your computer, so it is best to apply appropriate thermal paste to it.

Is Vaseline considered a dielectric grease?

A translucent compound known as “dielectric grease” is primarily used to seal and shield electrical conductors from sand, dirt, dust, and other foreign objects. On the other hand, petroleum jelly is referred to as Vaseline.
