Quiet PC A90 Fanless Z4

AMD’s low-power processors are a great way to get up to a 12-core system that generates absolutely no noise!

Features

  1. Fully built fanless PC system based around AMD’s latest processors
  2. Up to 128GB of fast DDR5 memory
  3. Selected components offer totally silent operation
  4. We build to your specification and deliver within 7 days
  5. Clean Build™ Promise and original OS+drivers supplied on DVDs
  6. Two year warranty with open-case policy

We are delighted to offer the A90 Fanless Z4, which is a fully-built ready to go silent computer system that utilises AMD’s processors and a very feature rich motherboard. The CPU is silently cooled by the Nofan 80-EH or the Noctua NH-P1 processor cooler for no noise, no dust, no moving parts and no maintenance. The machine can be configured to your exact specification and offers, as you would expect, totally silent operation. The PC is housed in Fractal Design Meshify or the North. Each case features large ventilation area at the top of the chassis allows for all of the heat generated by the internal components to naturally dissipate up and out of the chassis.

Total Silence!

At Quiet PC, one thing that truly bothers us is the abundance of marketing jargon claiming products to be “silent” or even “ultra-silent,” while in reality, they contain moving parts that inevitably produce noise. We firmly believe that silence is absolute; it either is or it is not.

That’s why we have gone the extra mile to create a PC that guarantees absolute silence. We have meticulously configured this computer to ensure a truly noiseless experience. The CPU cooler, power supply, and graphics cards are entirely passive, devoid of any moving components. Consequently, they generate absolutely no noise, offering you an exceptionally serene computing environment.

However, we would like to bring to your attention that the only potential source of noise in this PC would be if you choose to include a conventional hard disk drive (HDD) and/or an optical drive. Therefore, we recommend considering this while customising your system. If maintaining total silence is your goal, we highly recommend opting for a solid-state drive (SSD) to store your data instead of a HDD. Additionally, we suggest using the optical drive only when necessary, to keep any potential noise at bay.

With this carefully designed and crafted PC, you can rest assured that silence will reign, granting you an uninterrupted and peaceful computing experience.

AMD Ryzen Series

At the heart of the PC is a low-power AMD processor 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 performance each processors provides, take a look at the table below that shows some PassMark CPU Benchmarks, the higher the number the better the performance the processors offers.

Series Ryzen 5 Ryzen 7
7000 - Passmark 7600 - 27,966 7700 - 34,461
8000 - Passmark 8500G - 21,807 / 8600G - 25,921 8700G - 32,103
9000 - Passmark 9600X - 29,883 9700X - 37,698

The figures above are as of August 2024. 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 Ryzen 5 processors only. The Ryzen 7 and 9 generate too much heat for this heatsink. On the other hand Noctua’s NH-P1 is suitable for all processors on the configurator.

Motherboard Features and Options

This particular computer has an option of two motherboards, an ASUS B650 or an ASUS X870. Both motherboards are an excellent choice for this PC and both feature PCIe 5.0 speeds for the primary M.2 port (up to 128Gb/s), 2.5Gb LAN port and built-in Wi-Fi and Bluetooth. If you require a few more USB 3.2 Gen ports and an extra M.2 port, then the X870 motherboard might be for you.

B650-PLUS X870-PLUS

Wi-Fi version 6 7
M.2 ports (PCIe 5.0) 3 (1) 4 (1)
USB 40Gbps ports (Type-C) 0 2 (2)

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.
