Welcome to our guide to the quietest PC on the market. If you want a computer that’ll do its thing silently, without filling a room with irritating fan noise, then this is where you want to be. Many computer enthusiasts will advocate that the best way to get a quiet PC is to source the parts and build it yourself – this is arguably true, but isn’t a desirable option for everyone. So, all the quiet PCs we’ve included here are fully built and ready to use straight out of the box.

For this guide, we’ve made a total of five recommendations. First is our overall pick for the quietest PC – a recent model that impresses us with its performance while also running completely silently. However, this may not be the right quiet PC for everyone, so we’ve listed a few others with compelling differences – whether they’re smaller, cheaper, or better optimized for high-intensity tasks.

Why do PCs make so much noise? It’s all to do with heat. CPUs, the processors that power computers, generate a lot of heat – they just do. Figuring out how to control and dissipate this heat to prevent it from damaging the computer is one of the key design challenges of making a PC, and this is why so many powerful PCs come with big, whirring fans. They make a lot of noise, yes, but they also allow the computer to handle heavy-load processing tasks without overheating. 

Quiet PCs do away with the fans and use different methods of cooling. We’ll get into what some of these are and how they work later in the guide. Quiet PCs do come with some trade-offs in computer power that may affect whether one is right for you.

Reasons to buy

Practically silent
Great for general office use

Reasons to avoid

Not the most powerful PC

A relative newcomer to the market, the ECS EliteGroup LIVA Z3 is a tiny PC that uses a fanless design to run completely silently. Barely the size of a standard internet modem, the ECS EliteGroup LIVA Z3 is designed to be unobtrusive and keep out of the way. In a handy touch, it comes with a VESA mounting plate, meaning you can attach it to the rear of a compatible monitor, or mount it on a wall.

The ECS EliteGroup LIVA Z3 uses a Jasper Lake SoC CPU, released by Intel in 2021. As standard, it comes with 4GB of RAM, though there is capacity to upgrade this to 16GB if the user is so inclined. Default storage is 128GB, and it sports USB, USB-C and HDMI ports, as well as a headphone jack.

In use, the ECS EliteGroup LIVA Z3 runs in practical silence. There are no fans – there’d be no space for them in a unit this small – and passive cooling is achieved via vents in the sides of the chassis. Of course, this can only take you so far, so a number of other design choices have been made to help with heat dissipation. The Pentium Silver N6000 is not the fastest chip in this series, but unlike the faster N6005 SoC, it doesn’t require active cooling, negating the need for noisy fans. Also, its quad-core design makes use of thermal sensors that measure and adjust the clock speed in order to avoid overheating. 

Reviews of the ECS EliteGroup LIVA Z3 consistently praise its silent operation, and if you want a PC that’s going to stay quietly in the background, it’s one of the best options you can buy – with a caveat. The fact that the LIVA Z3 has to use a slightly less powerful chip to avoid the need for active cooling does mean that it’s not the most powerful PC around. For general office use, watching TV and online browsing, it’s going to be absolutely fine – and let’s be fair, this is all baked into the premise of a silent PC. If you want to enjoy high-end gaming, 4K streaming and resource-hungry applications, you are likely going to have to put up with a little fan noise here and there. For prioritizing a silent, out-of-the-way PC above all else, the ECS EliteGroup LIVA Z3 is an excellent choice.

While the ECS EliteGroup LIVA Z3 is a great option, it might not be quite right for you. However, we've got four more fantastic quiet PCs with slightly different specs that might suit you better below. 

What to look for in a quiet PC

Why is a quiet PC important?

There are lots of reasons you might want a quiet PC. For instance, plenty of people use a PC as their main device for streaming, by casting it to a TV screen. When you’re watching your favorite movies and TV shows, you don’t want to be distracted by huge amounts of fan noise.

By a similar token, those who host a lot of virtual meetings or presentations on Zoom or similar platforms will not want a loud, whirring computer to be constantly humming away in the background whenever they are talking. In some PCs, the fans and internal microphones are placed annoyingly close to one another, which can make for an unpleasant experience on the other end of the call. 

And it’s not just about the immediate user. Most of us share our living and working space with other people, and a loud PC can be a constant nuisance to another person trying to work or relax in the same room. If you want to keep your home life running smoothly, a quiet PC could definitely be the way to go!

Finally, quiet and silent computers can also be very useful for simple business tasks – particularly powering digital signs or billboards. As we’ve seen in our listings, many quiet PCs are small and unobtrusive things, easy to mount to wall or tuck away, meaning you can have them in your customer-facing business without bothering people with clutter or fan noise.

What are the trade-offs of a quiet PC?

With all this said, you may be wondering why everyone doesn’t use quiet PCs all the time. The fact of the matter is that there are trade-offs with quiet PCs that are worth being aware of before you decide to buy one.

The key factor is quite simply that a quiet or silent-running PC has a ceiling in terms of how powerful it can be. Remember that computer processing produces a lot of heat. Silent or fanless PC designs cannot run too hot, as they don’t have the means to cool down. Some will be designed with ventilation built into the chassis to help with heat dissipation, but this can only do so much. 

Some quiet PCs employ liquid cooling systems, which circulate a liquid glycol solution through the CPU heatsink in order to allow the heat to dissipate. These tend to be quieter than air-cooled systems, but they still do involve fans, which create noise. Plus, they add to the price of the PC.

A quiet PC can be a fantastic addition to your home – as long as you’re aware of its limitations. If you value peace and quiet over computing power, and would rather stream a movie in peace than be able to run the latest games in 4K, then a quiet PC should fit right into your home life.
