Adaptive Cooling Technology

The YampaNet TempraCool system is simply the best on the market, and this section explains why.  We will first explain our technology, and then compare it to other alternatives on the market.  If you are not into technology, skip ahead to learn more about system setup. 

Adaptive cooling is a process where fans run at the precise speed necessary to control your component temperature - no more, and no less.

The TempraCool system controls fan speed based on temperature. For normal room temperatures, the fans will run at an idle 50% speed. When the component temperature exceeds 73 degrees F, the fan speed will increase. Assuming the fans are placed in an appropriate position, the increased fan speed should keep the component temperature in check. However, should the component temperature keep increasing, the fan speed will also increase linearly, until the temperature reaches 95 degrees F at which the fans will run at 100%. The following diagram shows this relationship.

The benefits of adaptive cooling technology are noise reduction (quiet), energy savings, reliability, increased fan life and extended component life.  Each are explained in more detail on right the side of this page.  Following is a summary of these benefits and how they compare with other cooling alternatives.

Clearly, the YampaNet TempraCool solution offers the most.  But most important, your stereo components can expect extended life.  The TempraCool system runs fans at 50% idle speed when the system is cool.  We designed it this way because we want the components to have steady temperatures and reduce extreme changes.  We don't want extreme changes, because in electronics (i.e. your components), fluctuations of semiconductor junction temperatures are a major cause of component failure.

By designing our system around temperature and adding the proper temperature slope (sensor temperature at full speed - sensor temperature at idle speed), semiconductor junction temperatures can be held to near constant. As the air velocity over a typical semiconductor device changes by two-to-one, as it does when fan speed changes from full speed to half, the difference between the air temperature and junction temperature changes by a few degrees. Changing the air temperature by an equal number of degrees cancels this effect to hold absolute junction temperature near constant, improving component reliability.

In comparison, an alternative on the market is a cooling system that is 'always on'.  These are the low-cost home-made models that are simply a fan hooked to a power supply.  Although they are cheap and can cool your components, they are loud and use a 4 times the power!  And if a fan fails, there is no compensating circuitry to add cooling power.  We view this alternative as inferior.

Another alternative is a 'thermostat controlled' cooling system.  These run in two modes - they are either on with fans running at 100%, or completely off.  The problem is this causes spikes in temperature, which is hard on electronics.  Remember, fluctuations of semiconductor junction temperatures are a major cause of component failure.  Thus, cooling systems with thermostats are inferior and can lead to component failure.

You should evaluate other cooling systems, but when you do, pay attention to fan noise, and beware those that do not publish noise ratings.

In summary, the YampaNet TempraCool solution if the best on the market.  Yes, you can buy cheaper cooling systems, but they have the obvious problems described above.  It's better to invest in a proven solution rather than waste money on something inferior, only to come back here.

Adaptive cooling provides several distinct benefits:

• Noise Reduction - Fan noise has a logarithmic relationship to fan speed. This means that a small reduction in fan speed can yield a great reduction in noise.  Plus, our fans run at a maximum of only 11 dBA.
• Energy Savings - Fan energy consumption has a square relationship to fan speed. This means that by reducing fan speed by 50%, we can reduce energy consumption four fold of what it was.
• Reliability - The system adapts to environmental changes. As an example, if one of the fans were to fail, or a ventilation duct were blocked, or a component was added, the system would sense an increase in temperature and apply more speed to the operational fans
• Increased Fan Life - Fan life is increased by running at less than 100%; only as fast as necessary
• Extended Component Life - Because component temperatures are stable, fluctuations of semiconductor, which are  a major cause of component failure, are reduced.
