SIM - System Intelligent Management
Another feature of the Ikonik Zaria A20 is an option called SIM, or System Intelligent Management. This is a device that is both hardware and software based, and is designed to help you monitor the system to make certain that everything is working as it should be.
Above is the far side panel removed and if you look at this side of the optical drive tower, you will see the heart of this system. Let's take a closer look.
This is the SIM unit. In a nutshell, it has the ability to work as a rheostat device (powering from 7v to 12v depending on temperatures), a system temperature monitor, and a control device for cooling a reservoir. On top of all this, there is an included driver disk that allows you attach the USB cable to your system to give you access to the data and make changes to the parameters in which fans will work faster. This is done by means of temperature thresholds that you set. Choose the temperature for a given zone in which you want to have a set temperature, and the SIM will automatically monitor this zone and give more voltage to the fans in that area to attain your desired results.
To accommodate this functionality, the Zaria A20 comes with four thermal probes that connect directly into the SIM module. There are also four fan ports on the SIM that coincide with the thermal probes, so you have the ability to set certain fans to certain monitored zones. Use the software portion of the system to adjust your desired temperatures and the SIM will take care of the rest.
Just make sure to connect a Molex power coupler to the SIM to make it all work. The probes and the fans require power (of course) and the Molex is where it gets that power.
Positioned just to the rear of the SIM you will find a pair of slim line fans to help you with the need to exhaust that heated air that is rising from your components. Partially tucked in behind the power supply, there is enough of a gap to effectively remove that hot air from inside the box and allow your system to properly breathe.
By default, these fans are connected to the SIM module, but you can change this is you desire. The flexibility of the SIM allows you to set up your own zones and cool them in accordance with their needs. Since many of us are already proficient in monitoring the temperatures, this just makes things that much more customizable to your own system.
