Do You Need Thermal Paste For New CPU

Do you need thermal paste for new CPU? A lot of people are wondering if they need to buy thermal paste for their new CPU. The answer is, it depends on your specific needs and the type of CPU you have purchased.

For instance, if you’re upgrading an Intel Core i5 2500K to a newer Intel Core i7 4700HQ, then yes; you must purchase some thermal paste to get maximum efficiency out of your computer.

However, if you’re simply replacing a faulty component such as the power supply or video card with one from an older model like the Intel Core 2 Duo E8500 or AMD Athlon II X2 240e (which don’t require any additional cooling), there isn’t much point in buying more than what came with the new part.

What Is Thermal Paste?

Thermal paste is a substance that reduces the amount of heat lost from a computer’s central processing unit to its heatsink and helps lower CPU temperatures.

It is typically applied in a thin, even layer between the chip and heatsink. Thermal pastes generally have viscosities ranging from very thin liquids to thick pastes, but they are all meant to fill the microscopic air gaps arising at surfaces where two materials meet without being in contact with each other.

How Does It Keep Your Processor Cool?

Your processor has a heat spreader that is made of copper and dissimilar metals. The natural tendency for the metals in your computer would be to create an electric current and cause resistance, which generates heat.

Thermal paste works by filling in the gaps between these two materials making them one continuous piece so they don’t generate any more friction than they need to.

What Kind Of Thermal Paste Should You Use?

There are mainly two types of thermal paste: metal and ceramic-based pastes. Ceramic-based compounds use thermally conductive fillers such as boron nitride, aluminum oxide, or diamond powder to more efficiently transfer heat from the CPU into your computer’s heatsink and ultimately outside of your computer.

Metal-based compounds use metal powders such as aluminum, copper, and silver to better conduct heat between the CPU and heatsink.

The most popular thermal pastes include:

  • Arctic Silver – Ceramic based compound that uses micronized silver for high performance at an affordable price
  • Prolimatech PK-series – High-performance metal paste that uses aluminum oxide and titanium dioxide to maximize heat transfer
  • Thermal Grizzly Kryonaut – Ceramic-based compound for high thermal conductivity. This paste is the choice of professional overclockers, extreme gamers, and enthusiasts who want no compromises between reliability and temperatures.

Other than these popular brands other companies produce their formulations such as Cooler Master, Arctic Cooling, Deepcool, etc.

How To Apply Thermal Paste To A CPU?

Thermal paste is a type of material that is applied between the CPU and the heatsink to conduct heat away from the CPU. It’s important to apply the thermal paste before installing a heat sink, as it can help prevent problems such as overheating or damage due to contact with the metal surface of the CPU.

Here are some tips for applying thermal paste:

  • Clean off old thermal paste by wiping down both surfaces with rubbing alcohol.
  • Apply a fresh, new pre-applied adhesive pad (comes with most kits).
  • Peel the protective film off the adhesive pad and place it on top of one side of your processor or bare die.
  • Attach the heatsink onto the other side of your processor or bare die and tighten screws.

Be sure to not touch the thermal paste when installing or removing the heatsink. Use only approved, high-quality materials for your computer’s sake.


In this article on “Do You Need Thermal Paste For New CPU?”, we talked about what thermal paste is and why it’s important for your new CPU. Once you know the ins and outs of this material, maybe then we can give a definitive yes or no as to whether or not you need it with your purchase.

The function of thermal compound (also known as “thermal paste”) is simple – to transfer heat from one surface to another more efficiently. 

It does so by filling in the microscopic gaps between two surfaces and improving contact between them; if there are air pockets present instead of an even spread out layer, those will act as insulation and prevent heat conduction. So now that we’ve covered all the basics, here’s the real question: do you need to buy thermal paste for your new CPU?

In most cases, no. Unless it’s specifically recommended by a hardware manual or manufacturer–or if either of those two surfaces is damaged and requires extra attention before installation can take place-you probably don’t have to worry about buying this material.
