Info

The Intellifan technology operates on a direct, digital control-loop with the SMBus, regulating fan speed - regardless of the power supply voltage. This eliminates thermal lag, performance-degrading peripheral components, and facilitates immediate responses to immediate thermal requirements. It is the first fan technology to perform two-way communication with the system in serial digital format. How do I implement the Intellifan technology? Implementation is very simple. The Intellifan module is designed to operate as a slave on an I²C-based serial bus. Since it can also sink 4.0mA of current on the clock and data lines, it is also suitable for use on a high power SMBus segment. Why should I use the Intellifan? Intellifan provides several benefits:Lower Cost: less complex system design, lower power consumption, lower system cost, shorter design cycle, higher integration, and virtually no increase in per-unit costHigher Reliability & Performance: multiple speed ranges, greater efficiency, and longer fan lifeLower Acoustics: the Intellifan runs at minimum speeds required by thermal management system, generating lower noise levelsSoftware-Driven: the Intellifan is software-driven via the O/S or CMOS - enabling virtually limitless control and monitoring options Feedback and Diagnostics: speed monitoring, predictable failure points, real-time characterization and trendingRemote Manageability: with an internet connection, the administrator can monitor and manipulate the Intellifan from anywhere in the worldWill the Intellifan family continue to evolve? Yes. Currently, the Intellifan is available in 120x120x38mm, 60x60x25mm, and 38x38x28mm form factors - with future frame sizes to include (but not be limited to) 92mm, 80mm, 60mm, and 40mm fans. Additionally, as our clients' needs evolve, we will enhance and adapt the Intellifan technology to meet those needs. How does the Intellifan communicate with the system? The Intellifan uses the integrated JMC Controller with an SMBus/I²C-compatible interface to regulate and monitor fan speed, providing two-way communication with the thermal management system. The built in SMBus/I²C compatible controller employs four standard SMBus protocols: Write Byte, Read Byte, Send Byte, and Recieve Byte. Refer to the Intellifan product specification for more detail.
