5. My system has boot-up problems, or does not turn on...
The majority of these problems are not related to the Koolance system, but
to hardware or configuration issues. In a computer, a problem with the RAM,
motherboard, power supply, video card, processor, or monitor can cause the
system to appear not to boot-up properly.
If the Koolance radiator fans do not spin and the front LED Display Panel
does not light-up, check to see that the rear power cable is plugged in to the
slot adapter. If the fans and front LED display are lit, you are likely having a
separate hardware issue that is unrelated to the cooling system.
6. My system appears to be leaking fluid...
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 Testing
& Filling
).
If liquid should get onto another computer component, shut down the system,
and remove the component. In many cases, the hardware will be fine 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 where it can not be easily repaired, please
contact our Technical Department for further assistance.
7. My computer’s BIOS gives me errors that there is no cooling fan attached...
Some motherboards will not boot, or may generate an error or alarm if no
cooling fan is attached to the CPU or motherboard chipset power connectors.
There is typically an option to disable this warning in BIOS, but you may
need to boot with a fan attached initially to disable this setting. If the system
is not booting due to this problem, clear the CMOS and try configuring BIOS
again.
8. The LED Display Panel shows 5 - 0 or 5 - 5...
5 - 0 (“S - O”): Sensor open. This indicates a temperature sensor was not found
for the specified channel. If there is no sensor connected to that channel, this
is its normal status.
5 - 5 (“S - S”): Sensor short. This indicates that the sensor may be faulty or electri-
cally bypassed. If the sensor is listed with an “S-S” status, the cooling system alarm
will sound. The sensor should be replaced. Please visit our support web page.
