Fans

The Siberia features two proprietary fans connected to the same power cable. Primary fan — GlacialStars JT14025L12S001A, 1400 RPM. Secondary fan — GlacialStars JT9225L12S011A, 1200 RPM.



Primary fan advantages:

  • aerodynamics optimized for a good combination of performance and low noise,
  • enter bearing design,
  • Sanyo LB11961 operating circuit,
  • 4 illuminating LEDs, blue frame and propeller.


Secondary fan advantages:

  • decent aerodynamics optimized for performance,
  • enter bearing design,
  • blue frame and propeller.

There are no real drawbacks except for the simplified electronics of the secondary fan.

Ergonomics

The bracketry of Siberia is similar to that of Alaska. Bracketry for Intel platforms includes 2 universal brackets, 4 spring-loaded screws and 3 cushions. Bracketry for AMD platforms includes 2 brackets and 4 screws mounted to a socket cushion.

Note that Siberia's horizontal design limits access to screws, so the bundled spanner is a must for both AMD and Intel machines. On the other hand, this is compensated for by solid contact between the base plate and processor that guarantees improved heat contact and secure mounting.



Additional features of Siberia:

  • highly efficient Ice Therm II thermal grease (there's enough for multiple installations),
  • bundled spatula,
  • wide PWM adjustment range of the primary fan (400 RPM to 1400 RPM).




The only drawback is that the secondary fan speed is fixed at 1200 RPM, meaning that cooler noise doesn't get quieter than 26 dBA. But you can always use a rheobus or connect the fan to a 3-pin motherboard connector. This would allow you to reduce noise down to 20 dBA.
