Completely Fanless and Dustless — ideal for the factory floor, office, studio, or a silent home server. This fully fanless Xeon-based server supports ECC memory and RAID configurations, delivering reliable performance in environments where dust, noise, or vibration would compromise traditional systems.
Completely Fanless Design: Every major component of this HD Plex Fanless Server operates without fans — CPU cooling, chassis cooling, power delivery, and even graphics. The HD Plex H5 chassis uses a precision-milled aluminum heatsink design that transfers heat from internal components through high-capacity heatpipes directly to the outer enclosure, ensuring stable, silent, and maintenance-free operation.
The HD Plex H5 combines a compact footprint with an internal fanless ATX power supply, enabling support for higher-wattage CPUs, expansion hardware, and professional-grade components without compromising silence.
For absolute silence and maximum reliability, we recommend pairing this build with solid-state storage. The result is a powerful, durable, and completely silent Xeon server suitable for small business applications, industrial settings, and home environments where noise simply isn’t an option.
For users who need GPU acceleration—whether for creative applications, rendering, GPU-powered audio tools, or light gaming— this system can be configured with a fanlessly cooled RTX 3050. Using a custom heatpipe solution, GPU heat is transferred directly to the H5’s aluminum chassis, maintaining complete silence even under load.

To ensure your PC will never overheat all Fanless CPUs have their wattage limited to the cooling capacity of the heatsinks. Rest assured your fanless system will still get great CPU performance and also run totally silent. This wattage limitation will NOT affect normal usage but may be noticeable on some long CPU intensive processes. For more information on wattage limitation click here. Got questions?

Engineered for demanding environments, this fully fanless Xeon server is ideal for industrial settings, factory floors, studios, offices, or anywhere dust and noise are a concern. With no fans, no noise, and no moving parts, it delivers reliable performance in locations where traditional servers would quickly fail.
The Intel Xeon 6300 series processors are designed for entry-level servers, small to medium-sized businesses (SMBs), and edge/networking applications. They offers a cost-effective, modern, and reliable foundation for standard server workloads, balancing performance with power consumption
Every PC we sell comes defaulted with an NVMe M.2 SSD! M.2 SSD Drives and SATA3 Solid-state drives (SSD) have no moving parts, so they make no noise, have fast read times, and are more reliable than standard mechanical hard drives.
Quiet Video Cards We choose the quietest video cards available in the market. Every video card choice is either fanless or cooled using a stock hybrid fanless cooler. Hybrid coolers stay with their fans off unless the GPU is really working. This prevents the card from overheating and is still very quiet. Most people never know that the fan has turned on. As well as being absolutely silent every video card offers support for at least two monitors simultaneously, many with options for more.
ASRock Motherboard “Creativity, Consideration, Cost-effectiveness”. ASRock is the third largest motherboard brand in the world. The young and vibrant company has a reputation around the world for reliability. Our motherboards contain fanless heatsinks and heatpipes to effectively cool the chipset heatsink and voltage regulators, without the use of noisy fans.
ECC RAM can check and correct memory errors. A memory error can corrupt data and possibly crash a PC. For workstations and servers where errors, data corruption and/or system failure must be avoided at all cost, use ECC memory.
We don't just choose quieter parts, we choose the quietest, best performing parts available and assemble them cleanly to optimize airflow and minimize the slightest vibration. We don't just replace one or two parts in our PCs with relatively quiet components, we replace each component with the quietest part available. You will be amazed at how quiet our systems are!
And like always, SilentPC.com backs our systems with a great warranty along with the best professional, courteous technical service and support on the market today. Not sure what configuration would best suit you? Contact our Sales Team to receive a custom quote!
