Top Performance and Reliability

The PC itself doesn't compromise on performance, and can be built pre-installed with up to 64 gigabytes of memory and one of Intel's 7th Generation Core processors. Famous for their excellent performance/value balance, the processors have a quad-core architecture and under heavy loading, will automatically "Turbo Boost" their clock speed by up to 12%. We are now offering our systems with Ubuntu Linux pre-installed.

Unparalleled storage capability

The machine can be configured with up to 10 terabytes of internal storage, as a mixture of SSD or HDD devices, primarily depending on your requirement for speed versus budget. A "hot swap" hard drive can also be included as a convenient way of making data backups, high volume data transfer etc.

Which CPU cooler should I use?

The Nofan is offered with a choice of two CPU coolers, the Nofan CR-95C and the smaller Nofan CR-80EH. The Nofan CR-95C is ideal for processors up to 95W and we recommend the smaller Nofan CR-80EH for processors up to 65W.

Does the cooler cover the PCI-E x16 slot?

It is important to note that the larger CR-95 will cover the PCI-E x16 slot so you can’t use a graphics card in that slot if you choose that cooler.

While the smaller CR-80EH cooler doesn’t interfere with the PCI-E x16 slot, it is very close so if the graphics card that you choose doesn’t use a wrap-around cooler (one that also covers the back of the card), then it should fit in the PCI-E x16 slot.

It has to be said that if you do choose the larger Nofan CR-95C then having the graphics card fitted in the slightly slower PCI-E x8 slot doesn’t really impact on performance too much (5 – 10%) and it certainly doesn’t reduce the speed of the graphics card in half as many people believe.

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.

Therefore 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.

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.
