6. My system appears to be leaking fl uid...
Since users are allowed to confi gure their own coolers and clamps, it is
possible a connection was not properly sealed (however unlikely). If you can
see liquid somewhere on the tubing, or at the bottom of the chassis, computer
components may need to be removed for a system test (see Flow Testing).
If liquid should get onto another computer component, shut down the system,
and remove the component. In many cases, the hardware will be fi ne after
allowing it to dry. However, the system should not be operated until you have
discovered where the leak is coming from and can repair the problem. Should
the leak be situated somewhere in which it can not be easily repaired, please
contact our Technical Department for further diagnostic information.
7. My computer’s BIOS gives me errors that there are no cooling fans attached...
Some motherboards will not boot, or may generate an error or alarm if
no cooling fans are attached to the CPU or motherboard chipset power
connectors. There is sometimes an option to disable these fan connections in
BIOS, but you may have to boot-up with a fan attached initially to disable this
setting. If the system is not booting due to this problem, clear the CMOS and
try confi guring BIOS again.
8. The LED Display Panel shows “S - 0” or “S - S”...
Your Koolance LED display may specify if there is a problem with the cooling
unit. Please use the following guide in determining the cause of a problem:
S - 0 : Sensor open. This indicates that a temperature sensor may be discon-
nected or faulty. If sensor channel #1 is listed with an “S-0” status, the cooling
system alarm will sound because this connection is required. Sensors #2 and
#3 are optional connections.
S - S : Sensor short. This indicates that a sensor may be faulty or electrically
bypassed. If any sensor channel is listed with an “S-S” status, the cooling
system alarm will sound.
9. The LED Display Panel does not light up...
A defective display circuit is extremely rare. Usually, this is due to a misaligned
or disconnected plug on the Power Circuit (or Exos Slot Interface Adapter).
Verify that all appropriate plugins are attached, particularly the 12V 4-pin
power supply connection.
