Summary of WORLD’S FIRST! A COMPUTER WITH AUTO HEAT-UP? DFI 3.5” DESKTOP CS551 CAN RUN EVEN AT SUBZERO TEMPERATURES
DFI’s CS551 is a 3.5″ desktop single-board computer that packs Intel 8th/9th Gen Core processors and the Intel C246 chipset into a compact 146 × 102 mm footprint. It supports wide operating temperatures from -30 to 80°C with an auto-on heater, dynamic CPU/GPU workload balancing, ECC memory via C246, and is optimized for edge computing with high performance, small size, and extreme-environment adaptability.
Parts used in the CS551:
- DFI CS551 3.5″ desktop single-board computer
- Intel Core 8th/9th Generation processor (supported)
- Intel C246 chipset
- ECC memory (supported via C246)
- Auto-on heater
- Cooling solution (designed for -30 to 80°C operation)
- CPU and GPU with dynamic workload allocation
As edge computing has been rapidly expanding to every corner, users pursue computers to drive more functions with better performance to enhance artificial intelligence analysis capabilities, which brings three new criteria in hardware selection for edge applications: processing power, size, and adaptability to extreme weather. DFI, one of the world-leading industrial PC providers, newly released the 3.5″ desktop single-board computer (SBC), CS551, is a perfect match for this situation with a breakthrough in aspects of size, footprint, operating temperature, cooling, and expansion.
High Performance With Small Footprint
Compared to most of desktop motherboards in the market that can only be merely downsized to Mini-ITX form factor (195mm (7.7″) x 170mm (6.7″)), DFI has further shrunk CS551 footprint by nearly half to 3.5″ (146mm (5.75″) x 102mm (4.02″), with support for the Intel Core™ 8/9 Gen processors and even the Intel C246 chipset that provides ECC support for memory at Intel Xeon server-grade level, maximizing the performance of the entire computer.
3.5” Desktop Platform With -30~80°C Wide Temp. Support
SBCs are prevailing in outdoor applications of Internet of Things due to small footprint, and to overcome the outdoor extreme temperature fluctuations, CS551 breaks the limitation of operating temperature merely support at 0~60°C by 8th /9th Gen Intel Core Processors, and further extends it up to 80°C, down to -30°C. Even the temperature drops below zero, the auto-on heater can warm up and keep the processor within the operating temperature range. Equipment can thus operate normally without being shut down in snow!
Dynamical Adjustment Between CPU & GPU
In addition to the powerful processor with wide temperature support, the CS551 also features the dynamical adjustment between CPU and GPU by allocating the computing resources according to the workload. Even in high temperature environment like 80°C, the computing work can be adjusted by the CPU and GPU intelligently, and prevent computer crash down as well as greatly improve the stability of the application.
