We are proud to announce this totally fanless PC, the Nofan A850a with AMD’s latest processors that offer up to a massive 40% performance improvements compared to previous AMD processors. The CPUs incorporates multiple cores and threads, which allow them to excel at multi-core processing events such as gaming, video editing, photo-processing, while simultaneously running other programs. It also boasts overclocking capabilities (but we do not recommend this for a fanless system) and support for dual-channel DDR4 memory.

Total Silence!

One thing that annoys us as Quiet PC is all the marketing blurb about products being silent. No doubt you have heard some manufacturers claim their products are “silent” or even better “ultra-silent” when their products contain moving parts. There are no variations to the word “silent”, it either is or isn’t, it’s that simple. If a product contains a moving part it will generate some noise and will not be silent. We have therefore configured this PC to allow you to purchase a totally silent computer. The CPU cooler, power supply and graphics cards are totally passive, meaning they will generate absolutely no noise as they have no moving parts. In fact the only way you will be able to make this PC generate noise would be to purchase it with a conventional hard disk drive and/or an optical drive, so please bear that in mind when configuring the system. If total silence is your aim, then opt for an SSD to contain your data rather than a HDD or SSHD, and only put a disk in the optical drive when needed.

Graphics Card Options

Some of the processors available with this system have integrated graphics, but there are some that don’t. This can be a little awkward when configuring the system, as to whether a discrete graphics card is needed or not. To try an make things clearer, all processors that include built-in graphics have the following, “with Radeon Vega Graphics” in their product name.

The number within “Radeon Vega Graphics” indicates how many graphics cores each processor has. For example, the AMD Ryzen 5 2400GE with Radeon Vega 11 Graphics, has a total off 11 graphics cores. The larger the number the greater the performance.

Chassis options

We have made this is system available to build into two different chassis. The compact Cooler Master Q500L or the be quiet Pure Base 600. Apart from the physical size of each chassis they are both more than adequate at accommodating a fully fanless system. We recommend that if you opt for the Pure Base 600 that you either remove or open the top vent to allow the warm air from inside the chassis to naturally dissipate out of the chassis.

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 choose an SSD or M2 drive as a boot drive that contains the operating system and important programs. A conventional HDD would store other data but remember that if you intend to have a totally silent PC, you might want to forgo the HDDs altogether 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 Microsoft Security Essentials / Windows Defender - 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 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.
