Does CPU Come With Thermal Paste: Latest Update

I get this common question: Does CPU Come With Thermal Paste? While the rule of thumb indicates that it does, there are a few points to consider.

So, if you just bought a new CPU, do you get thermal paste already applied?

If no! I have enough resources for this Item.

First and foremost, thermal paste is never applied directly to the CPU. If it is present, it is connected to the CPU cooler that comes bundled with your new processor (in most cases).

The second point: While most modern CPUs include some form of integrated cooling, some models (both Intel and AMD) do not.

Thermal paste is critical for keeping your CPU cool and can help improve performance in one form or another. Therefore, double-check that it has been applied before using your brand-new CPU.

Now, let’s take a closer look at thermal paste, a critical component of your new purchase.

What is Thermal Paste, and Why Do I Need It?

Thermal paste (alternatively referred to as “thermal grease,” “thermal compound,” “thermal solution,” or TIM [Thermal Interface Material]) is a material used to plug microscopic air gaps between a processor and its heat sink.

Thermal paste’s primary function is to conduct heat away from the CPU and toward the heat sink. The heat sink’s purpose is to heat away from the hardware. This technique maintains the CPU’s temperature, allowing it to continue performing resource-intensive tasks.

Thermal paste is available in two varieties: conductive and non-conductive, each with its advantages.

Conductive thermal pastes are more efficient at transferring heat than non-conductive thermal pastes. Because non-conductive thermal pastes degrade rather than resist shear stress, they are easier to apply than conductive thermal pastes.

Conductive thermal pastes are used in various new heatsink and CPU combinations because they provide an effective solution to common heat problems. However, some users report that using non-conductive paste on their processors improves cooling performance.

Why Use Thermal Paste?

Because it is a relatively obscure component of personal computers, it is easy to overlook. However, it is a critical component that contributes to the longevity of your computer.

Thermal paste is referred to by various names, including CPU paste, thermal compound, thermal grease, thermal gel, and heat sink gel.

You’re likely to have heard someone use one or more of these terms when discussing PC construction, specifically the CPU and CPU cooler.

It is typically a semi-liquid, greasy substance with a silver or gray hue. It is available in a squeeze bottle or tube format and is composed of thermally conductive materials.

That is, this gel is highly efficient at conducting heat. And it is precisely because of this property that thermal gel is functional.

When you use our computers, they generate a great deal of heat. As a result, every computer (desktop, laptop, or notebook) contains a cooler, either an air- or water-cooled system.

The cooling system removes excess heat and dissipates it into the surrounding environment, effectively cooling the internal components.

In this case, the thermal gel contributes to the cooling system’s overall performance. Typically, you apply the gel between the CPU and the cooler’s base plate.

Additionally, the gel facilitates faster heat transfer between the CPU and the cooler due to its high heat transfer capability.

This allows the CPU to cool down significantly faster. Thus, the thermal gel substantially improves the cooling system’s overall efficiency.

How to Apply Thermal Paste Properly Step by Step?

Step: 1 Cleaning old thermal paste

This is, without a doubt, the most critical step in applying new thermal paste. If you’re using an older thermal compound, chances are it’s already performed admirably. The issue is that if the old thermal paste has dried out, it will create air pockets, preventing your cooler or heatsink from efficiently transferring heat to the processor!

Before removing the old thermal paste, you should ensure that no power is being supplied to your computer. If you leave the computer on, you risk short-circuiting everything and possibly frying some components! Allow the computer to cool down after turning it off!!!!

In most cases, probing through old thermal paste with a sharp object should be pretty easy, but if this is not the case in your point, use a metal brush and begin scrubbing!

Additionally, try gently scrubbing the processor’s edges. For some reason, removing old thermal paste from that area is significantly more complex than in other areas.

Step2: Applicating Thermal Paste

You can now begin reapplying new thermal paste. You do not need to purchase anything expensive for this, but you may want to consider investing in some high-quality thermal compound if you frequently overclock your computer!

What quantity of thermal paste should you use? If you’re using a syringe-style thermal paste, apply just enough to the processor’s center and spread it with the plastic top.

If you’re using a thermal pad, it’s likely to come packaged in a cardboard sheet with pre-applied thermal paste. Remove the protective layer and apply it directly to the processor’s center.

Step3: Put Your Parts Back Together

Once all components are ready for connection, reconnect them. Ensure that the processor is not scratched and that all connectors fit snugly.

Can a CPU Work Without Thermal Paste?

The thermal gel does not process information like a circuit board, unlike a CPU or GPU. So, yes, you can run a computer without thermal paste. You don’t want to.

The issue is that the cooler does not have an airtight connection to the processor or graphics card. There are usually many microscopic holes between the cooler and the processor. These gaps slow heat transfer and eventually damage your processor.

When two metal surfaces are joined, tiny gaps or pores appear. Unchecked gaps will trap air and create small air pockets. Due to its high resistance, the air is a poor heat conductor. So the air pockets slow down heat transfer.

The thermal gel fills in the voids between the metals. Between the cooler and the processor, it acts as a tiny bridge.

The cooling system fails to cool the CPU effectively without the thermal gel. And if your CPU gets too hot, the internal circuitry will fail. Eventually, your CPU will fail, and your PC’s performance will deteriorate.

That’s why thermal gels are vital when building a PC. And if you want your computer to run smoothly and last a long time, use thermal gel on your CPU. Otherwise, you’ll be visiting the hardware store far too frequently.

How Do I Check For Thermal Paste On My CPU?

As previously stated, the actual processor or CPU will be devoid of thermal gel. As a result, you cannot purchase an Intel or AMD processor that comes pre-installed with thermal paste.

Rather than that, the paste is attached to the CPU cooler’s base plate, which is then attached to the processor. Likewise, for the GPU cooler.

Now, many processors include a stock cooler consisting of pre-applied thermal paste. Typically, the manufacturer will apply the paste to the heat sink, the portion of the cooler that comes into direct contact with the processor.

While using the stock CPU cooler, check for any traces of thermal paste on the base plate or heat sink. Typically, the paste will be three or more stripes of silvery gray material.

Both Intel and AMD (the company that makes Ryzen processors) will include stock coolers and thermal paste with their CPUs.

When purchasing an aftermarket CPU cooler, you should inquire whether it comes pre-applied with thermal paste.

If it is not, you can easily purchase the paste separately. Following that, you can either apply it yourself or have the technician do so. Of course, enlisting the technician’s assistance will incur a service charge.

Take care not to over-apply the paste, as excess can seep into the sockets and other components of the circuit.

Does Thermal Paste Have an Expiration Date?

Yes, thermal pastes do have a shelf life. However, this period’s duration depends on the type of material used to manufacture the paste.

Most thermal pastes have a shelf life of three to five years, depending on the material used. However, this is possible only if the cap is installed correctly and the paste is stored in optimal condition. Otherwise, the paste will quickly deteriorate.

If you used the paste only once during the initial phase of PC construction and did not open it until then, the paste should be fine. However, this is not a guarantee.

How to Check Thermal Paste Expiration?

Because the shelf life of a tube of thermal gel varies significantly, it is best to check the gel before each use.

Squeeze the paste onto a metallic surface that is not connected to your computer. The paste has expired if it comes out dry, clumpy, or inconsistent.

Consistency is critical when it comes to the thermal paste. If it lacks the necessary smoothness or viscosity, it will clog your processor.

As a result, you should always discard expired thermal paste unless you want to put your computer in grave danger.

When Should the Thermal Paste Be Replaced?

This is a common source of concern for computer owners. Furthermore, there are a few instances where you should replace the thermal paste inside your computer.

To begin, whenever you remove the CPU cooler for cleaning or replacement, you should always apply a fresh batch of thermal paste.

Ensure that you completely wipe away the old paste with isopropyl alcohol and a clean cloth. Then apply sufficient paste to form a thin layer when attaching the cooler to the CPU.

Alternatively, some individuals recommend replacing the paste every few years, regardless of whether the cooling system is opened or not.

Additionally, you can incorporate this into your two- to three-year maintenance check. However, repeating this process annually will be unnecessary.

How to Choose the Best Thermal Paste For Your CPU?

Following the eight steps in the right section will allow you to select a thermal paste compatible with your CPU.

What is your budget?

Examine your monthly budget for thermal paste. For example, if your budget is around $20, choose a thermal paste in that range. Higher-end thermal pastes cost up to $100, but they are not suitable for everyone.

What’s your CPU?

First, you must determine whether your CPU is an Intel or AMD processor. Using this data, decide between a Thermal Interface Material (TIM) and a Thermal paste.

What is your CPU cooler?

Before buying, make sure the thermal paste’s type and size (thickness and width) are compatible with your aftermarket cooler (heatsink and fan).

What is your expertise?

Before purchasing, beginners should read reviews or research the types of thermal pastes compatible with their CPUs. If you plan to change your thermal paste, copy the existing thermal paste on your CPU. Always check with your dealer or the manufacturer’s website if removing the factory default thermal paste is safe.

(W/mk) How much Thermal Conductivity do you need?

Because some processors operate at temperatures above 70°C, it is best to use a compound with thermal conductivity of 8.5W/mK.

What features do you like?

No need to worry about dust proofing and non-electrical conductivity. However, liquid metal thermal pastes are only suitable for extreme CPU overclocking.

Do you require antioxidants?

Ceramic-based thermal compounds are non-conductive and have low oxidation levels because they contain no metal or silicone.

It is usually grey and has good heat transfer properties. Silver-based compounds are also effective and compatible with most CPUs and heatsinks.

However, it is not recommended for beginners due to the health risks associated with lead solder exposure when applying soldering paste on your CPU. Overclockers love liquid metal pastes for their high conductivity. But only Intel processors support liquid metal pastes.

How about a new thermal paste?

Choose the Noctua NT-H1 or Arctic MX-4 if you want good thermal paste without breaking the bank.

Even on a tight budget, you can find great products.
