We’re now offering a fully-built 100% silent PC, using AMD’s 7000 series processor and a fanless processor cooler. This high-specification machine doesn’t compromise on performance and comes with a two-year warranty.

Introducing the Quiet PC A70 Fanless Z4 - a cutting-edge, fully-built silent computer system featuring Intel’s latest generation processor and an ASUS motherboard. Experience the power of silence with our innovative cooling options: the Nofan’s IcePipe processor cooler or Noctua’s NH-P1. These cooling solutions offer noiseless, dust-free, and maintenance-free operation.

Customise the system according to your exact specifications, and enjoy a truly silent computing experience. The PC is elegantly housed in your choice of either the Fractal Design Focus 2 or SilverStone’s SETA, both of which feature a spacious ventilation area at the top of the chassis. This design allows all the heat generated by internal components to naturally dissipate upwards and out of the chassis, ensuring optimal performance without any noise distractions.

Ryzen 7000 Series

At the heart of the PC is a low-power AMD AM5 7000 series processor powered by the new ‘Zen 4’ architecture, ushering in the next era of high performance for gamers, enthusiasts, and content creators thanks to the featuring up to 12 cores and 24 threads. Compared to the previous generation, the low-power AMD processors enable single-core performance improvement of up to +29%, up to 45% more compute for content creators, up to 15% faster gaming performance in select titles, and up to 27% better performance-per-watt, compared to the 5000 series.

To give you an idea of much of an improvement the low-power 7000 series is over the 5000 series processors, take a look at the table below that shows some PassMark CPU Benchmarks, the higher the number the better the performance the processors offers.

The figures above are as of January 2023. They do change over time.

Choosing the correct CPU cooler

As mentioned above, this system can be configured with either Nofan’s 80-EH IcePipe or Noctua’s NH-P1 CPU cooler.

Nofan’s CR-80EH is suitable for the Ryzen 5 and Ryzen 7 processors only. The Ryzen 9 generates too much heat for this heat. On the other hand Noctua’s NH-P1 is suitable for all processors on the configurator.

Motherboard Features and Options

This specific computer model utilises either the ASUS PRIME B650-PLUS or the ASUS PRIME X670-P WIFI motherboard. Both motherboards come with 2.5Gb ethernet, two M.2 ports, HDMI 2.1, and DisplayPort 1.4 connections. The primary difference between them lies in the X670 model, which offers a greater number of USB ports on the rear, providing users with more connection options, as well as having built-in Wi-Fi and Bluetooth.

Storage considerations

When specifying your new PC’s storage options using our system configurator below, you will be offered a choice of drives which vary by price and capacity. There are two primary types of storage. A conventional hard disk drive (HDD) offers huge storage capacity for a low price, but it won’t be especially fast and it will generate a certain amount of running noise since it contains a constantly-rotating spindle. A solid state (SSD) or a M2 drive on the other hand, offer tremendous speed and absolutely silent operation, but they cost more than an HDD for any given capacity.

So if you need a lot of storage space (for videos or large quantities of digital photos for example), then we would recommend an HDD. On the other hand, if you prefer silence and speed (especially boot-up speed), then an SSD or M2 drive would be a better choice. Of course you can have more than one drive, so you could have the best of both worlds by choosing one of each! We recommend that customers chose an SSD or M2 drive as a boot drive that contains the operating system and important programs and a conventional HDD to store other data, but remember that if you intend to have a totally silent PC you might want to forgo the HDDs all together as they will make some noise due to their moving parts.

Clean Build™ Promise

These days, many pre-built PCs often rely on cash incentives from software companies to support their prices. These companies pay hardware manufacturers to pre-install limited or trial versions of their software, hoping that customers will eventually opt to upgrade to the full version. Unfortunately, this approach has a downside: it fills the new PC with unnecessary “junkware,” leading to an inflated operating system and performance issues.

At Quiet PC, we firmly believe that customers deserve the utmost performance from their brand new PCs. That’s why we proudly offer our Clean Build™ promise with every system we build. When you choose one of our PCs, we install only the essentials: the operating system (if requested), motherboard drivers, OS updates and Windows Security. Say goodbye to annoying pop-ups and nag screens. With our clean build promise you can immediately start using your new PC without the hassle of uninstalling numerous unwanted programs. Experience lightning-fast boot times and enjoy optimal performance for months and years to come.

Free hardware support and fully inclusive warranty

We offer free hardware technical support for as long as you own the machine. This support covers any hardware query or problem, including advice on maintenance and upgrades. We regret we can’t offer software support or training so we would recommend contacting the software vendor in this instance.

Our hardware warranty runs for at least two years and is “collect and return” meaning that you don’t need to worry about getting the machine back to us - we will instruct our courier to collect it from you on a day of your choosing, then after we have checked and repaired it we will send it back to you by express courier at our expense. In addition, unlike many other PC suppliers, we have an “open-case” policy which means you are free to open the machine and perform your own minor modifications or upgrades without worrying that your warranty might be affected.

The A70 Z4 is also available in the SilverStone SETA chassis
