 fan Speed control – Computer Power Supplies
Why fan control is important.
There is one major and one minor reason:
• Fans normally run at 100% speed, which is noisy and unnecessary. In any case the fan speed should be varied according to temperature.
• Fans running at 100% will draw unnecessary power
The CPU cooler fan is often too noisy. If your PC is noisy then the chances are that it's the CPU fan - you may even have a 'screamer', and then the choice is to replace it, or cut the speed, as it just isn't necessary to run at full speed all the time - if ever. Normally the CPU cooling fan only needs to run at about 75 or 80% just when the PC is under heavy load, since fans are over-specified.
Case fans can often run even slower, at about 50 or 60% speed, as they work fine like this. They are usually much quieter than the CPU fan anyway, but cutting the unnecessary speed has the benefits of less total noise, and lower power consumption.

Stroboscope |
 led stroboscope – from Control Resources
In electronic stroboscope (or strobe lights) have a lamp capable of emitting brief and rapid flashes of light. The frequency of the flash is adjusted so that it is an equal to, or a unit fraction below or above the object's cyclic speed, at which point the object is seen to be either stationary or moving backward or forward, depending on the flash frequency. |

Telecom |
 telecom cooling from Control Resources - SmartFan fan speed control products regulates fan speed based on temperature (thermistor), control signal (PWM or DC) or I2C communication link. Temperature alarms and fan failure alarms are available on many fan speed control models. Complete custom fan speed control design and manufacturing services as well as custom fan tray assembly are available to provide you with the optimum solution for your telecom application. |
