Thermal Considerations
6.1.
Active Cooling
The KISS 4U V3 SKX platform is forced air-cooled using a fan assembly with three system fans that force air to flow
from the air-intake ventilation holes on the front side to the air outlet ventilation holes on the rear side. The three
system fans are controlled by its own internal temperature sensor. Two temperature sensors are positioned on the
rear side air outlet ventilation holes and one temperature sensor is positioned on the right side behind the drive bays.
This enables variations in ambient temperature and power dissipation to be controlled.
If a filter pad is used to stop dust and dirt entering the system, clean the filter pad regularly to ensure that the filter
pad does not obstruct the airflow, see Chapter 10.1: Cleaning the Filter Pad.
Operate the KISS 4U V3 SKX only with a functional fan assembly!
Replace a defective fan assemble only with Kontron’s original fan assembly. see Table 2:
Accessories and Spares Parts.
Additionally, each of the dual CPUs is equipped with an active cooler controlled by the mainboard. The PSU is
equipped with a fan to extract air directly at the rear of the system.
6.2.
Minimum System Clearance
To guarantee that sufficient air flows from the front to the back of the system, ensure that ventilation holes are not
covered, blocked or obstructed by surrounding parts.
Before installing the KISS 4U V3 SKX take into account, any thermal considerations mentioned in Chapter8/:
Installation, such as airflow obstructions and the correct orientation.
Ensure Sufficient Airflow.
Ensure the KISS 4U V3 SKX is well ventilated and that nothing obstructs the KISS 4U V3 SKX
from taking in air at the front and exhausting air at the rear.
Do not place the KISS 4U V3 SKX close to heat sources or damp places.
There are no ventilation restrictions above and below the KISS 4U V3 SKX, enabling
installation directly on top of or below another system.
6.3.
Third Party Components
When extended and configured with third party components such as PCIe expansion cards, DIMMs and drives (HDD,
SSD DVD), there is an internal temperature rise. Thus, the air temperature inside the KISS 4U V3 SKX is higher than the
ambient temperature around the system.
