Extreme quietness in a small package

Apart from the tiny UltraNUC, the DA2 Fanless is one of the smallest PCs we offer. Unlike the UltraNUC, the DA2 Fanless uses a conventional fully-featured motherboard, albeit a Mini-ITX sized one. The machine can accommodate one M.2 SSD and up to two 2.5” hard drives. And because we offer the latest power-frugal processors, it can be cooled fanlessly, thanks to the fanless CPU cooler. The power supply is the Streacom ZF240, so unlike the power supplies in many other small PCs, this one is fully integrated so there are no clumsy black “bricks” which you need to have lying around behind the PC. The benefits of fanless operation include zero noise, does not attract dust, no moving parts, meaning the PC requires very little to no maintenance.

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.

Feature packed motherboard

This PC features the ASRock B650E mini ITX motherboard, which is packed with features such as HDMI 2.1, PCIe 5.0, 2x M.2 ports, Wi-Fi/BT and an array of USB 3.2 ports. Once thing to mention is by default the motherboard has a built-in fan for the PCIe 5.0 M.2 port. Considering this PC can only be configured with a PCIe 4.0 M.2 then the fan is not necessary as the heatsink alone is more than adequate at cooling the M.2 drive, even is a fanless system. We therefore remove the fan on the M.2 drive, making it a truly fanless system. Of course, when PCIe 5.0 M.2 drives are widely available we will test them without the fan installed to determine if the fan is required for cooling or not.

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

The price of many pre-built PCs these days is often supported by cash kickbacks from software companies who pay hardware manufacturers to pre-install limited or trial versions of their software and then hope that the customer pays to upgrade to the full version. The downside to this approach is that the new PC comes pre-loaded with a lot of “junkware” which bloats the operating system and can cause severe performance degradation.

Here at Quiet PC we believe that customers have every right to expect the best possible performance from a brand new PC, so every system we build comes with our Clean Build™ promise. We install the operating system (if you order one), motherboard drivers, OS updates and Windows Security - that’s it. You won’t be pestered by pop-ups and nag screens and you can get on with using your new PC immediately without having to uninstall lots of junkware first. Your new machine will boot in super-quick time and will stay running quickly for many 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.
