Fan Controller
An optional fan PWM controller is available. Customer can purchase the configuration with the fan controller installed.
If you require the fan controller upgrade you need to contact our Sales Team ([email protected]).
The upgrade can only be done in house (at OSS manufacturing plant).
You have to send the unit back to One Stop Systems.
The upgrade involves the following:
1.
Changing the three fans
2.
Connecting new wires
3.
Setting up the Dip switches on the fan controller
.
4.
Drilling holes beneath the enclosure for mounting the PWM controller device.
Parts required: You need to order a set of fan (qty 3) and 1 PWM controller. Contact our Sales team for details. The photos below are an
example of two units: one unit with fan controller installed and one without the fan controller.
The 4U 5-slot Value Expansion chassis is designed to work with all types of PCI Express cards. Some PCI Express cards produce substantial heat
and must be cooled properly to eliminate over heating problem. There are three fans located at the front of the enclosure to provide cooling
required for the hottest PCI Express cards. As safety measure, by default the OSS provides 4U 5-slot Value expansion chassis with the fans
functioning at full speed to prevent high-heat generating PCIe cards from over-heating.
If noise is a concern, we provide an optional fan PWM Controller to help alleviate fan noise in situations when a low heat producing card is
installed in the expansion unit. You can manage the velocity or speed of the fan by adjusting the "Adjustment Knob" to the desired percentage.
When the PWM percentage is at 100%, the fan spins at maximum speed. When the PWM cycle is at 0%, the fans are stopped.
When card or GPU is overheating the performance throttles down. When GPU generates a load of heat and when your cooling solution can no
longer dissipate heat fast enough to keep temperatures within a safe range, your graphics card starts to dump performance. In order to
maintain performance, you need to control the heat by providing ample cooling and good airflow.
