1. Silverstone SST-HE01-V2 – Heligan

Best Pick

The Silverstone SST-HE01-V2 is a great cooler for various systems, especially for users who want to get the most out of their budget.

The company claims that their SST-HE01-V2 can outperform the competition by providing superior cooling and low noise.

The heat pipe design is the key to this claim, as it transfers heat from the CPU to the fins and then from the fins to the base. This provides better thermal efficiency and means that you wont need to increase the fan speed to get adequate cooling.

While the company doesnt specify what fan they used, they mention that the fans are made from quality materials, and the blades have been designed to minimize turbulence.

Ive owned a few coolers before, and the fans on my previous ones were noisy. This was especially true when I was using high-end graphics cards, but its nice to know that Silverstone has fixed this problem.

The SST-HE01-V2 has an adjustable fan, which lets you choose the best speed for your system. I recommend a medium setting for most users, as its ideal for lower-end CPUs and GPUs.The only downside is that you cant swap the fan if it fails, which is disappointing.

2. Nofan CR80EH

I have a lot of experience with fans, but for a while, I was using a radiator, and it was very warm. So I bought a fanless radiator and was impressed with how much cooler it made the room.

The Nofan CR80EH was designed with performance in mind. Its fanless and has multiple heat pipes that transfer heat to the radiator.

This product is a dual-pass radiator, meaning that it has two heat pipes and transfers heat to the outside of the unit. The other feature that makes this radiator different is its maximum TDP of 80 watts.

Most other fanless radiators have a TDP of 100 watts or less. With this product, you wont have to worry about it overheating.

And because its fanless, there are no moving parts to get stuck and break, making it last longer than traditional radiators. Installation is easy with the included instructions and is compatible with Intel and AMD motherboards.

The only thing that could be improved is the build quality. It feels cheap and is not as sturdy as the other products. But this isnt something that will affect the overall performance of the product. Overall, its a great fanless radiator that will perform better than traditional radiators.

Thing To Consider Before Buying THE Best Fanless CPU Coolers

To keep your computer cool while running, you can turn to several different devices.CPU coolers are among the most common, with both the cooler and the fan being used to provide cooling.

The fan is usually powered by an electric motor, pushing air across the CPU’s surface (central processing unit). This is done to create a cooler environment around the CPU so that it doesn’t become as hot. A fanless CPU cooler is a less common type of device which uses thermal pads to achieve the same results.

A good fanless CPU cooler will also come with a fan, but it can be turned off, making it perfect for those who don’t want to hear the whirring of a fan. Here’s a list of things to consider before choosing THE best fanless CPU cooler.

Thermal Pad Design

The design of a thermal pad will significantly impact how well it cools the CPU. There are three basic types of thermal pad designs:

  1. Conductive
  2. Porous
  3. Packed

Conductive thermal pads are solid, so they’re more likely to make a good seal against the CPU, but they also conduct heat away from the CPU. Porous thermal pads are made of mesh, so they don’t make a good seal, but they don’t conduct heat.

Packed thermal pads are made of a substance that’s designed to absorb heat, and they’re usually much thicker than either of the previous types. You’ll often find that manufacturers will try to get the best of both worlds by offering a combination of porous and packed thermal pads in one thermal pad design.


The materials used in a fanless CPU cooler can have a significant impact on the product’s ability to cool the CPU. Thermal pads are usually made of aluminum, copper, or ceramic.

Aluminum is a very common material for thermal pads because it’s lightweight, durable, and conducts heat well.

Ceramic has a higher thermal conductivity than aluminum but is also heavier and more expensive. Copper is the most expensive of the materials, but it’s also the most efficient at conducting heat.If you need to keep costs down, aluminum might be the best option.


A fan is often used in a fanless CPU cooler, and it can help to keep the cooler from overheating. A good fanless CPU cooler also includes a fan speed control, so you can set the speed to suit your preference. You should also look for a fan with high airflow, as this will help to keep the fan from overheating.


When buying a fanless CPU cooler, you’ll need to make sure you buy one that fits your particular motherboard.

A larger CPU cooler is better suited to larger CPUs, as the fins will provide a bigger surface area, and it will help to provide a greater cooling effect.

On the other hand, a smaller cooler is better for CPUs that are smaller in size. This is because the fins will be closer together, and they’ll be able to reach a wider temperature range, so it will provide a better cooling effect.


A fanless CPU cooler may not need a warranty, but you should always check the manufacturer’s policy to ensure they offer a warranty.


In conclusion, You need to use something fanless with a good performance. It is possible to achieve a lot of efficiency with a fanless cooler. For example, you can easily lower the noise level of a cooling system by 90 percent. Fanless coolers are very quiet and can help save a lot of energy.
