If you get bothered by the CPU cooler noises, you are not the only one. As a person who’s on his PC all day, I found it quite annoying having to deal with the constant whirring of the CPU cooler. So I changed my CPU cooler into a Fanless one.

And trust me when I say it makes a night and day difference! It feels fresh and more relaxing than ever.

Here, I will show you the 3 best Fanless CPU Coolers available on the market today.

But in case you’ve to decide right away, choose the Noctua NH-P1 cooler as our top recommended model. It will give you the best value for the money for sure.

3 Best Fanless CPU Coolers You Can Buy Right Now

You can only use a fanless CPU cooler if you are using a low TDP CPU. Since the whole heat transfer process is passive, it is impossible to cool down high TDP or overclocked CPUs passively as they require rapid heat dissipation.

That’s why if you are using an OCed processor, go for other cooling solutions. In that case, check out our best coolers for overclocking CPUs.

On the other hand, if you have a low TDP CPU and want to get rid of the constant noise coming from the PC, buying fanless components can save you from not only unwanted sound. But you can also get a CPU cooler with fans and even maintain a quiet environment. Check our 7 Quietest CPU Coolers to choose yours.

Here are the 3 best fanless CPU coolers available:

1. Editor’s Choice: Noctua NH-P1

SPECIFICATIONS

• Product Dimensions: 6.22 × 6.06 × 5.98 inches
• Supported Socket: LGA 1700/1200, AM4/AM5, TR4/TRx4/SP3
• Weight: 2.64 pounds
• Material: Copper heat pipes and aluminum cooling fins

Why We Picked It

To design a powerful rig that gives the best performance while being completely silent, there aren’t any other alternatives to Noctua’s NH-P1 silent cooler. This cooler has a unique design, unlike any other heatsink that I’ve seen.

There are only 13 aluminum fins which is a fraction of what you generally have on a normal heat sync, and they are spaced super far apart. So that the heated air they create has room to blow itself outward, and new fresh air can take its place.

For mounting the NH-P1, the Noctua uses their SecuFirm2+, which is very reliable to support the massive weight of the cooler itself.

We’ve tested this cooler in an Intel Core i7-11700F PC with Nvidia 3060 TI and 32 gigs of RAM. When we run a 16-thread small FFT prime95, the processor still runs at 4.38 GHZ.

Also, we have tasted NH-P1 in the i9 12900 PC with other competitors in the Fanless CPU Cooler market. Here’s the result we have found.

Here you can easily see how well this cooler has performed compared to other alternatives in the market. You should also check out our other Noctua fans for your CPU if you want to lower your temperature even more.

Who It’s For

We recommend Noctua NH-P1 to everyone who wants a silent pinpoint environment while maintaining the temperature of their PC. Besides, people who like unorthodox PC builds can also try this passive cooling solution for their rig.

What We Liked Most

We mainly liked the build quality and effective design of this cooling device during our test. And also, its astonishing cooling performance was beyond any fanless CPU cooler we have ever seen.

What Could Be Improved

The main demerits of this cooler were its huge size and weight. NH-P1 weighs over a kilogram, which doesn’t fit in most PC cases. Also, the $110 seems a bit much, even though the Noctua fans are usually worth every penny.

Verdict

From our viewpoint, Noctua’s NH-P1 model is the most effective fanless cooling system that works with most modern CPUs. If you want a calm and quiet environment and don’t do a huge amount of intensive work, just go for it.

2. Best looks: Nofan CR-80EH

SPECIFICATIONS

• Product Dimensions: 6.1 × 6.1 × 4.45 inches
• Supported Socket: LGA 115x, 1366, 1200, AM4, AM5, sTRX4, TR4
• Weight: 10.6 ounces
• Material: Copper pipes

Why We Picked It

Well, for a fanless CPU cooler, Nofan CR-80EH performs remarkably with CPUs up to 80W TDP. It has an array of aluminum and copper heat pipes that round the cold copper plate in circles. These heat pipes conduct heat into the air, which passively cools your CPU.

The Nofan CR-80EH manages to cool down a regular CPU satisfactorily. Your CPU wouldn’t experience thermal throttling unless you use a high TDP CPU or an overclocked one.

We tested the Nofan CR-80EH with an Intel i9 11900T CPU and the Asus Prime Z690A motherboard. In a 30-minute Cinebench R23 run, we get a 78℃ to 80℃ reading on HWmonitor for the first 30 minutes, which is good for any normal PC user.

The size of the cooler is also in the sweet spot. It’s big enough to conduct heat efficiently but small enough to fit in most cases.

However, you might not want to go that far and stay within 65 Watts TDP CPUs for the best results.

What We Liked Most

We mainly liked the looks and the size of the Nofan CR-80EH, besides its cooling facility. Unlike most passive coolers, it easily fits into most PC cases.

What Could Be Improved

We didn’t like its low TDP count. The 65 Watts TDP seems very basic to us. So they should try to increase the TDP threshold to increase their customer base.

Who It’s For

I would advise buying the Nofan CR-80EH only if you are going for a zero-fan setup. If you, however, add some components to your PC that have fans, it will generate some levels of noise, which will fail the ultimate goal of a silent PC.

Verdict

The Nofan CR-80EH is a great passive cooler for low-end PC users. Its compatibility, effective cooling, and compact size will attract many customers across the globe.

However, besides its capabilities, we became addicted to its all-golden cylinder shape. That’s why we gave it the Best Looks award among the choices.
