Building a new PC can exist a daunting task, but this experience tin can also be very heady. Either way, you lot definitely exercise not want to rush the process.
There are many factors to take into consideration, and minor errors can cause serious harm to very expensive hardware components.
One such expanse that requires exceptional care is the installation of the CPU – and a primal component to this installation is the thermal paste.
Now, if y’all’re non sure how and when to add this medium, the post-obit article will give you a rundown of everything you demand to know. Nosotros volition cover how to safely install the processor and bring yous one step closer to finalizing your PC’s associates.
Do CPUs Need Thermal Paste at All?
CPUs tend to run hot, resulting in temperatures that can reach upwards of 100 degrees Celsius. This tin can cause the processor to throttle, which in turn causes the PC to stutter, freeze, or fifty-fifty shut down. If continued for likewise long, catastrophic failure may follow.
To keep the CPU’southward temperatures in check, a libation is a necessary component that must be connected to the processor.
These coolers can either utilise a fan’southward static pressure – which chills a heatsink that dissipates the CPU’s thermal energy – or a liquid coolant (commonly ethylene glycol).
The latter absorbs the processor’s estrus, is transferred to a radiator in social club to be chilled, and is then carried back to the CPU to repeat the procedure.
No thing which type of CPU cooler you lot opt for, it will e’er be attached to the processor via a cold plate. Cold plates are fabricated of either copper or aluminum and are meant to blot heat from the CPU’southward integrated rut spreader (IHS).
The contact made between these two materials will never exist optimal due to imperfections in the metals that can crusade micro-air bubbling to be trapped betwixt them.
Therefore, a liquid medium is required to mediate their connexion and minimize thermal resistance. This is where a Thermal Interface Textile (TIM) is applied, and why it is
for maintaining proper operating temperatures for the CPU (which should be under 70 to 80 degrees Celsius).
The thermally conductive chemical compound eliminates any air gaps between the cold plate and the processor, insulating the interface expanse and maximizing rut transfer.
Do AMD CPUs Come With Thermal Paste?
A rule of thumb to remember is that thermal paste will never come attached to the CPU itself. Rather, it may, or may not, come pre-applied on the cold plate of the CPU cooler.
This means that AMD’south processors will, indeed,
include thermal paste; unless they are boxed with a stock cooling solution. AMD’s heatsinks will unremarkably come up in the form of a Wraith Stealth, Wraith Spire, or Wraith Prism air cooler.
For the new generation of Zen 3, Ryzen 5000 Serial CPUs, the just processor to include a thermal solution (a Wraith Stealth) is the Ryzen 5 5600X.
Their previous generation, Zen two, Ryzen 3000 series CPUs have far more than stock-cooled options to choose from. Only the Zen 2 Ryzen 9 series and Ryzen 7 XT series CPUs do not come with a cooling solution.
If you purchase a CPU unboxed (or OEM), a CPU libation will not be included; unless the CPU is inside a pre-built desktop. For second-manus CPUs, it is always best to use your own thermal paste.
Do Intel CPUs Come With Thermal Paste?
Similar to AMD, Intel’s CPU will also
include a thermal paste; unless the CPU is boxed together with a CPU cooler. That beingness said, their stock heatsinks do come up with a pre-applied thermal paste.
For Intel processors, whatsoever boxed not-1000 and non-X variant CPU will include a cooling solution. For example, the Intel i7-11700 processor volition include a cooler, whereas the i7-11700K volition not.
If you’re looking for a CPU cooler for a new Intel K-variant processor, make sure to check our listing of the all-time coolers for the job.
generation Rocket Lake processors are boxed with a PCG 2019C cooler, which is rated for up to 95 Watts of Thermal Blueprint Power (TDP).
Practice You lot Need to Apply Thermal Paste to a New CPU When the Cooler Has Pre-Applied Thermal Paste?
Whether you’re purchasing an AMD CPU, an Intel CPU, or a third-party CPU libation, the amount of pre-applied thermal paste volition more than than suffice for the installation.
Adding additional thermal paste to the CPU is sick-advised, equally mixing pastes is never a good thought.
Pre-practical thermal paste does, even so, accept its own downsides. Many times the thermal paste is uniformly added to the cold plate, which may cause the compound to spill over the socket when tightening the cooler downward to the CPU.
This will besides be the case when adding besides much thermal paste, as the excess volition exist squeezed out when installing the libation.
Overflowing thermal paste can become an issue when removing the CPU cooler from the CPU, which is a necessary pace when upgrading or switching out motherboards, for example.
These two components, the heatsink and the CPU can become stuck and become difficult to separate.
Additionally, the quality of thermal pastes can differ vastly, and many overclocking enthusiasts will rightfully prefer to have their own thermal paste variant applied to the CPU cooler rather than compromise with the pre-applied paste.
If you lot’d like to find the best thermal paste for your needs, make sure to check out our commodity for a more detailed guide. Tom’s Hardware has likewise tested 90 thermal paste products and ranked them according to dissimilar needs and applications.
In either case, if the thermal paste is to exist removed, it must exist done and so using high-concentration rubbing alcohol; placed on a microfiber textile (ideally) or a paper towel.
After removing the thermal paste – and drying the surface of the cooler’due south cold plate – the new thermal paste tin and so be applied to the CPU and not the CPU cooler.
Notation that many CPU coolers will include a syringe of thermal paste rather than have it pre-applied and so that users tin apply it based on their own preference.
How to Properly Apply Thermal Paste
To properly use thermal paste, you lot volition first want to adhere the CPU to its socket on the motherboard and make sure it is secured.
Next, you will want to place a pea-sized corporeality on the heart of the CPU’s heat spreader. Another fashion of applying the paste includes placing smaller dots almost the corners of the CPU and a fifth dot in the middle: known as the “penta-dot method”.
Now, at that place have been many debates on how much thermal paste should be practical to the CPU. Also, does the method of dispersing the paste affect the CPU’s thermal performance? The truth of the matter is that existent-world benchmarks (Linus Tech Tips) have proven that the differences of these diverse methods are all simply negligible to a CPU’due south operating temperatures.
Even the amount of applied thermal paste will make little to no divergence, given that a minimum threshold is met (Gamer’s Nexus).
A rather simple but useful guideline is to make sure that the surface of the heat spreader is covered with thermal paste
the CPU cooler has been attached and tightened down.
This is why a pea-sized amount will generally suffice. Subsequently applying the paste, make sure to store it properly so that it lasts for your next upgrade.
For the best way to store the thermal paste sufficiently, make sure to cheque our comprehensive guide.
Assembling components that are worth hundreds of dollars can exist a stressful ordeal, though one that can too be both elating and definitely rewarding.
When information technology comes to installing a new CPU and its accompanying cooler, post-obit some general guidelines will always keep you safety.
Firstly, make sure your CPU cooler of choice includes thermal paste, either pre-practical or in a tube. The last affair you want is to accept to wait for i to arrive, or get out looking for 1 when the time comes to build your new figurer.
CPU-manufacturer stock coolers will always come up with a pre-applied paste. If your CPU model does not come up with an accompanying cooler (boxed or unboxed), and so you will need to purchase the thermal paste separately.
Secondly, if the paste is pre-practical (and to your satisfaction), simply connect and tighten the libation to its socket, and y’all are all set.
If the paste is not pre-applied, place a pea-sized portion of the thermal paste on the middle of the CPU’southward heat spreader, and then connect and tighten the libation to its socket.

Do CPU Coolers come up with Thermal Paste?
Yes, all CPU Coolers come up either with a pocket-sized tube of thermal paste or some thermal compound already applied to the lesser of the heatsink.
Do Intel CPUs come with Thermal Paste?
All Intel CPUs that come with an included boxed libation also come up with thermal paste. The thermal paste is either applied directly to the included libation’due south heatsink or is included in a tube.
Is pre-applied Thermal Paste any good?
Pre-applied thermal paste is good plenty to run the CPU it accompanies at stock speeds. For lower temps and higher clocks, specific thermal paste, compound, or liquid metal can accomplish superior results.
