Systems
Alarm & Shutdown Settings
By default, the Koolance audio alarm will sound if any sensor reaches 55ºC (131ºF).
When the system alarm sounds, the appropriate LED temperature will flash in the
display and the radiator fans and pump will increase to 100% power.
To change this setting for an individual sensor, choose the desired channel with
SET, and press and hold
▼ + ▲ together for 3 seconds. The alarm temperature
will begin flashing. You may change this value from 0ºC (32ºF) up to 99ºC (210ºF).
The normal temperature reading will resume if you do not press any buttons for
4 seconds.
To reset all temperature alarms to their default (55ºC / 131ºF) setting, press and
hold the ºC/F button until “dEF” flashes in the display. NOTE: This will also reset
the fan speed mode to “auto”, and pump power to 100%.
If any temperature sensor reaches 3ºC (5ºF) above the alarm temperature, the
system will shutdown power to the computer via the Koolance “ATX pass-through”
wire. With default alarm settings, this means the system will shutdown if any
sensor reaches 58ºC (136ºF).
CAUTION:
Generally, sensors report liquid temperature at the water
block, which is typically 5-10°C (9-18°F) lower than the actual heat
source. This difference must be considered if adjusting alarm/shutdown
temperatures. Activating alarm/shutdown modes at too high of tem-
perature can cause hardware damage. Please see the Koolance CPU
water block user manual for information on attaching this sensor.
