COOLING SYSTEM
The Rear Exhaust TriCool fan
The Sonata II comes with one 120mm TriCool fan preinstalled with silicone grommets in the rear.
Note: The default setting of the fan is Low. We recommend this speed to maximize the quiet
computing experience.
This fan has a three-speed switch that lets you choose between quiet, performance, or maximum
cooling. (See specifications below.) The fan is installed so that the air is blowing out of the case.
Connect a large 4-pin connector from the power supply to the male 4-pin connector on the fan.
Note: The minimum voltage to start the fan is 5V. We recommend our users to set the fan speed
to High if you choose to connect the fan to a fan control device or to the Fan-Only connector
found on some Antec power supplies. A fan control device regulates the fan speed by varying
the voltage to it. The voltage may start as low as 4.5 V to 5V. Connecting a TriCool set on Medium
or Low to a fan-control device may result in the fan not being able to start. The already lowered
voltage from the fan control device will be further reduced by the TriCool circuitry below 5V.
Specifications:
Size: 120 x 120 x 25.4 mm
Rated Voltage: DC 12V
Operating Voltage: 10.2V ~ 13.8V
The Front 120 mm Fan
This case comes with one optional 120mm fan mount in the front right behind the 3.5" internal
drive bays. The front fan should be installed so that the air is blowing into the case from the front.
Note: We recommend NOT using the front fan for maximum quiet computing. If you
choose to install a front fan, we recommend using Antec TriCool 120mm fan and set the speed to
LOW.
The Advanced Chassis Air Guide (ACAG)
Note: We strongly recommend running the ACAG without any fans since adding fans
means adding noise. The ACAG runs from the rear of the case to the CPU to provide fresh,
cool air to the CPU without the help of any fans (passive cooling). It comes with two optional
fan mounts - one 92mm mount for the CPU and one 80mm mount for your high performance
VGA card (for active cooling).
CPU Cooling
You can adjust the 92mm CPU fan mount on the ACAG in three directions so it can be positioned
right on top of your CPU cooler.
Installation/Adjustment of the ACAG
Note: Before installing the ACAG be sure that you have installed all of your expansion cards first.
