Airtop 3


Introducing the new Airtop 3 – a ruggedised small-form-factor fanless IoT edge server powered by an 8-core Intel® Core™ i9-9900K Processor and Nvidia Quadro RTX 4000, both passively cooled using Compulab’s Natural Airflow technology. With a footprint of just 7.5 liters, Airtop3 can passively dissipate up to 300W and operate at a wide temperature range of -40°C to 70°C. Airtop3 ships with a 5 year warranty.

The Airtop 3 is built to your specification, a selection of options is available on from our online store however if you can't find the configuration you require please call us directly on 02 8313 7122 for a chat about the unit. 

Fanless Core i9 9900K and Quadro RTX 4000

IoT edge server can reduce processing latency, network bandwidth requirements and TCO, provided that it is sufficiently powerful, robust and easy to deploy.

Airtop3 presents a unique value proposition for edge computing in harsh environments:

  • Exceptionally high performance – 8-core, up to 5 GHz Intel Core™ i9-9900K or Intel Xeon coupled with Nvidia Quadro RTX or GeForce GTX GPU and high RAM capacity up to 128 GB

  • Rich storage, networking and I/O, each can be enhanced thanks to Airtop3’s modular design

  • Passive cooling across wide temperature range and a rugged all-aluminium small-form-factor housing

  • Maintenance-free design, tool-free serviceability and advanced monitoring and diagnostics provisions

Airtop3 performance and features

Airtop3 supports 9th Generation Intel® Core™ i9 Processors and future Intel® Xeon® E Processors, including the highest power 95W Core i9-9900K. The maximum RAM capacity is 128 GB DDR4-2666. Standard storage is comprised of 6 devices – two NVMe SSDs – up to 2 TB each and four 2.5” SATA 3 HDD/SSD with RAID support. Standard networking includes two GbE ports and support for Wi-Fi 802.11ac and 4G modem. Standard I/O includes 3 4K displays, 6 USB 3.1 ports, 3 RS232 and audio. This feature set may be satisfactory in some cases, but IoT has many specialised applications – deep learning may require a discrete GPU, automotive applications often require high capacity of high-speed storage, machine vision usually utilises integrated PoE ports. For these use cases and other, Airtop3 offers functional enhancements.

Airtop 3  supports 7 displays

Enhanced graphics

Airtop3 has a PCIe x16 (PEG) slot with Natural Airflow passive cooling that supports up to 160W Quadro RTX 4000 graphics card. This powerful CPU + GPU setup is effective for low latency edge analytics workloads involving image recognition, machine learning or inferencing.

The four displays of the graphics card can work in tandem with the integrated graphics for a total of seven 4K displays.

Enhanced storage

The standard two NVMe cards and four 2.5” SATA SSD/HDD support up to 20 GB with RST or software RAID and are passively cooled in a dedicated thermal zone.

Storage can be enhanced using Airtop3’s NVM3 card installed in the PEG slot. NVM3 supports additional three NVMe cards up to NF1 30110 form factor.

NVM3 enables remarkable data rate of over 9500 MBps and increases max storage capacity to over 60 TB. It allows installing SSDs with power loss protection (PLP).

Enhanced networking

Dual Gbit Ethernet (Intel i210 + Intel i219) and optional WiFi 802.11ac + 4G/LTE modem are available as a standard. For higher bandwidth, dual 10 GbE card can be installed in the PEG slot. Extra networking capabilities can be added using a FACE Module

  • FM-LAN adds 4 independent GbE ports – useful for routing applications

  • FM-PoE adds 4 GbE ports, each with 802.3af PoE source which simplifies setups involving IP cameras

  • FM-OPLN adds 2 GbE SFP+ optical LAN ports which enables longer range, better immunity and higher security

Cooling, durability, modularity and monitoring

Airtop3 cooling is based on Compulab’s Natural Airflow technology that stimulates airflow without moving parts – by the waste heat of the 3 major heat sources (CPU, GPU and storage devices) each having a dedicated thermal zone.

The 7.5 litre housing is all-aluminium made of die-cast and extruded parts with precision machining for seamless fit, shock and vibration resistance.

Airtop3 supports Compulab FACE Modules (Function And Connectivity Extension Modules) which enable various application specific networking and I/O capabilities. A new FACE Module designed specifically for Airtop3 – FM-AT3 adds 2x USB 3.1 gen 2 (one USB type-C) + 1x USB 3.1 gen 1, front audio jacks, mini-PCIe socket with SIM card, micro-SD and diagnostics LEDs for troubleshooting RAM, BIOS and display issues.

It is very easy to install RAM and storage devices in Airtop3 thanks to the clam shell tool-free opening.

Airtop3 includes the I3M OLED display – for displaying vital runtime information including clock rate, temperature and power consumption.

Built-in diagnostics

Airtop3 incorporates built-in diagnostics LEDs on the front panel that provide immediate visual indication of the initialization process – RAM detection, BIOS POST and detected displays. This feature saves precious technician time during troubleshooting. Further system information is available on the I3M display.
