Installation

Supposed we had a motherboard with several 4 pin outlets for fans, we would have to plug the fans into the outlets and that’s all.

However, when the only feeding for a 4 pin fan is that of the CPU cooler, it would be necessary to unplug the installed fan. Instead, we plug the Arctic Fan PWM’s male plug, and to its female part we plug the CPU cooler that until that moment, it was plugged directly to the motherboard. We have an extra 3 pin plug which is to be inserted into any fan outlet of the motherboard with RPM sensor, and in this way, it would be possible to find out the speed of each of the two fans, but with the great advantage that both are controlled.

As it was mentioned before, in this way it is feasible to connect up to 5 fans. So if this is what we want to do, we just have to chain up the fans, being the CPU cooler the last one to be connected.

The goal achieved with this was to make all the fans work according to the necessity. In normal conditions, the dissipation requirements will be low; therefore the fan speed will be slow, and the PC will be extremely noiseless. For example, if we used the PC to play or to do any other activity that required a bigger effort, the temperature will rise and consequently, the fans will start spinning at a higher speed until the demand diminishes. In that moment, the speed will go down again.

In short, the fans spin according to the moment’s need and thus, a quiet environment is obtained. All this controlled simply by the BIOS and with no installation or software configuration. Awesome!
