3.8 System Cooling
Three 8 cm chassis cooling fans (located in the center of the chassis) provide cooling airflow
while two 8 cm exhaust fans expel hot air from the chassis. The chassis is also fitted with
an air shroud to balance the overall system thermal performance. The fans should all be
connected to headers on the motherboard. Each power supply module also has an integrated
cooling fan.
Note: When using consumer grade GPUs, fan speed setting must be set to Heavy IO.
Fan Failure
Under normal operation, all three chassis fans, both exhaust fans and the power supply
fans run continuously. The chassis fans and the exhaust fans are hot-swappable and can be
replaced without powering down the system.
Replacing Rear Exhaust Fans
1. Push down the red tab and pull outwards to remove the exhaust fan.
2. Replace the failed fan with identical one. Install it in the same position and orientation.
It should click into position when fully inserted. Check that the replaced fan is working
properly.
