The newly-announced uGuru technology is one of the distinctive features of ABIT KV8-MAX3 mainboard. Let’s find out what this technology actually does. According to marketing papers from ABIT, the special-purpose ABIT uGuru microprocessor makes the “heart” of this technology. But if you dare to rip off the uGuru sticker from this “special-purpose” processor, you will see a chip from Winbond, which is an embedded W83L950D microcontroller based on the Turbo 8025 architecture with 40KB of flash memory, 256 bytes of internal RAM and 2KB of external SRAM. ABIT uses this controller to control the fans, to store the BIOS profiles and to save the overclocked frequencies from Windows.
If we stick to the ABIT’s own terminology, ABIT uGuru technology consists of several parts:
- FanEQ is the most interesting component that serves to control the rotation speeds of the fans. It controls the CPU fan as well as the fans on the North Bridge and in the OTES system. The key point of the technology is simple: you can set it up to reduce the rotational speeds when the temperatures of the system components are low enough. You can enter the bottom and top threshold values when the cooler works at its slowest or highest speed. Between these two critical temperatures, the rotational speed of the fan changes linearly. You can configure FanEQ either in the BIOS (where you can also set up the maximum and minimum voltages sent to the cooler) or in a special Windows-based utility.
Thanks to the FanEQ technology, you can reduce the noise from ABIT KV8-MAX3 greatly. This technology is really very useful, considering that this mainboard has two additional high-speed fans.
