With all the new CPUs that were released this year, the heat dissipation has become a major issue in building a silent PC. Especially the new 12nm Skylake line of CPUs, which are known to be very power hungry. Here are the best Fanless CPU Coolers tested to Build a Silent PC :
As PC gaming continues to grow, so do the need for silent fans. In the past, computer fans have been loud, but builders are now realizing the importance of quiet cooling for gaming. Some builders are choosing liquid cooling, which is more expensive and requires more maintenance. In our opinion, the best way to cool a PC is through air cooling, but that’s not always possible. In this series, we are going to show you different cases and fans that we have tested to see if they are able to be reasonably quiet when used as a PC case fan.
What makes a good CPU cooler? How much cooling should a CPU cooler provide? What is a silent PC? How do you test a CPU cooler? The purpose of this article is to answer these questions.

Our Recommendation for the 7 Best Fanless CPU Coolers
If your CPU has a low TDP, you can only utilize a fanless CPU cooler. Because the whole heat transfer process is passive, cooling high TDP or overclocked CPUs passively is difficult because they need fast heat dissipation.
So, if you have a low TDP CPU and want to get rid of the continuous noise coming from your PC, purchasing fanless components may save you not only money but also time in the long run.
The top 7 best fanless CPU coolers are as follows:
1. Heligon Silverstone SST
The Silverstone SST-HE01-V2 – Heligon passive CPU cooler is the most effective passive CPU cooler available.
The Silverstone SST-HE01-V2 – Heligon has the following features:
- Included is a 140mm PWM low-noise level fan.
- Intel and AMD CPUs are supported.
- aluminum fins with a large diameter
- up to three 140mm fans may be supported
- CPU with a TDP of up to 300W
- six heat-pipes that have been soldered
Check out the current price of Silverstone SST Heligon.
Both in terms of performance and sound, this passive cooler shines. Let me explain how it does this.
The six soldered heat pipes link the copper base with the heatsink’s aluminum fins. These heat pipes are of exceptional quality, providing maximum heat conductivity.
The aluminum fins have been designed to be broad enough to reduce the sound of air passing past them. It also aids in the rapid dissipation of heat.
This passive cooler is unique in that it can be used as a conventional CPU cooler by adding fans. It allows up to three 140mm fans to be added to turn this passive CPU cooler into a normal one. It functions well in this manner.

The best thing is this:
The highest TDP that can be supported is outrageously large, reaching 300W. However, with such a high-heat-producing CPU, a passive cooler would not suffice.
A 140mm PWM fan is included in the cooler, enabling you to adjust the fan speed based on your CPU temperature or personal preferences. It’s up to you whether you want to run it slowly for less noise or quickly for a performance increase.
In PWM mode, the Silverstone SST-HE01-V2 – Heligon effectively transfers heat away from the CPU. The high efficiency of this passive CPU cooler is the primary reason for its outstanding performance across the system.
Its height is also not excessive, and at 164mm, it would fit inside most modern PC cases. The building is of exceptional quality. Although the mounting method is not difficult, there is still space for improvement.
Overall, the Silverstone SST-HE01-V2 – Heligon is an excellent option for passive CPU cooling.
- »Works well in PWM mode
- »Deafeningly quiet
- »extremely effective
- »It’s possible that the mounting mechanism may be improved.
Nofan CR-80EH, Nofan CR-80EH, Nofan CR-80E
Anyone searching for a low-noise PC might choose the Nofan CR-80EH.
The Nofan CR-80EH has the following features:
- a number of heat pipes
- totally devoid of fans
- CPU with a maximum TDP of 80 watts
- 155x113x155mm in size
- Weight: 300 g
Check the current price of the Nofan CR-80EH.
It’s a fanless CPU cooler, as the name implies. It does not come with a fan and does not facilitate the addition of one. To function, the fanless cooler is completely reliant on external airflow.
Now comes the crucial question: how does it perform?
It works well for a fanless CPU cooler. The fanless cooler can handle CPUs with a TDP of up to 80W. For the best results, you may not want to go that far and stick to CPUs with a TDP of 65 Watts.
Don’t forget to look at the finest noctua cpu cooler on the market as well.
In terms of cooling,
The aluminum and copper heat pipes of the Nofan CR-80EH circle the cold copper plate in circles. Heat is transferred to the air via these heat pipes. Here, the whole procedure is passive.
The Nofan CR-80EH does a good job of cooling down a standard CPU. Thermal throttling will not occur unless you use a CPU with a high TDP or one that has been overclocked.
The cooler’s size is also right on the money. It’s large enough to effectively transmit heat yet tiny enough to fit in most situations.
Only purchase the Nofan CR-80EH if you want a completely silent system with a fanless PSU, GPU, and enclosure. If you add certain components to your PC that have fans, though, you will hear some noise. At that moment, a silent CPU cooler is preferable than a fanless one.
- »Excellent cooling for a cooler without a fan
- »not for CPUs with a high TDP or for overclocking
3. Fanless CPU Cooler from Mustwell
The Mustwell Fanless CPU Cooler is a massive passive CPU cooler radiator that can also be used in conjunction with a fan for maximum performance.
The Mustwell Fanless CPU Cooler has the following features:
- Support for a 120mm fan
- six heat pipes made of copper
- radiator with no fans for cooling
- Intel LGA 1150/1151/1155/1156/1366/775/2011 sockets are supported.
Check Mustwel’s current price.
This product may be used in two ways. It may be used as a passive CPU cooling without the need of a fan. The six heat pipes made of copper generously transmit heat to the aluminum fins, which are then dissipated into the air.
This mode is suitable for a setup with no sound. Another advantage is that there will be no dust buildup.
The Mustwell Fanless CPU Cooler may also be used as a radiator. It can accommodate a single 120mm fan. This arrangement will act as a radiator heatsink for the fan, with the fan being in charge of quickly removing the heat. The fan, however, must be purchased separately.
Check out the TR4 socket compatible CPU cooler.
It performs well in both situations. After all, it is a passive CPU cooler. Keeping that in mind, it effectively cools low-power CPUs.
It’s a shame that this single heat sink doesn’t come with any mounting brackets. Aside from that, the Mustwell Fanless CPU Cooler performs well for the price.
- »consistent cooling
- »Use case with several purposes
- »There are no mounting brackets supplied with this product.
