Because VARYC Predictive Fan Controller is designed after physical principles and dynamics, it is not limited to a specific platform. The controller can be adapted to chip vendors products, a computer manufacturers PCs, a motherboard developers boards, a CPU Fan vendors fans, industrial ventilation systems, and etc.

The following tests are made with two different motherboards, one a mid range the other a high end board, from two popular motherboard vendors and an Intel processor. The purpose of the tests is to compare the VARYC Predictive Fan Controller with two popular fan controllers on the market.

Vendor 1

46 % Fan Speed Reduction

The tests are performed with different CPU loads so that different scenarios can be depicted.

As shown above, the VARYC Predictive Fan Controller uses a staggering 46 % less fan speed. The reason for this is because the VARYC fan controller predicts temperature changes, and the unique control algorithm makes sure smooth changes are made before temperature increase.

.. at the cost of only 0.82 ℃

Because VARYC Fan Control reacts quickly and uses the full range of your fans capabilities it makes sure that your fan is using exactly the amount of speed it needs, nothing more or less.

Even though the average temperature of the CPU increases with 0.82 ℃ with the VARYC fan controller, it is still well below the Intel thermodynamic specifications.

Vendor 2

24 % Fan Speed Reduction

The same test scenario as the above is used. As seen in this figure, this motherboard's fan controller is much better than the above, yet still VARYC Predictive Fan Controller outperforms it by an average of 24 %. The peak difference is actually 41 %.

.. at the cost of only 1.13 ℃

As the above example, the temperature difference is very low compared to the large reduction of fan speed. Some systems have a strict temperature requirement and the controller can be tuned to accommodate this request while still reducing the average fan speed.
