Koolance EX2-755-R - Manual (Page 15)

22 23 User Manual
We hope your Koolance system will provide you with years of reliable cooling
performance. To help avoid unnecessary RMA issues, we have prepared this list
of possible operational problems, and their most common solutions.
1. The pump does not appear to be operating properly...
Pumps need to be “burped” during the initial bleeding process to avoid this
situation. Reduce pump speed (but not low enough to stop the pump).
While the pump is running, gently tilt the system in various directions until
coolant begins moving. Open the fill port to relieve excess air.
2. My temperatures seem too high...
Verify that the liquid coolers are making sufficient contact with each
component. Ensure thermal paste has been applied (but not excessively),
that the block’s protective bottom film has been removed, and that the water
block is positioned correctly (see the cooler’s manual). Also check there are
no blocks, twists, or crimps in the tubing.
Finally, a dusty Radiator can result in higher temperatures. Please see
Draining and Maintenance
for more information.
3. When I adjust the temperature alarm settings, it skips number increments...
This is normal operation if your LED is set to display in Fahrenheit, because
the temperature program is based on units Celsius. Some ºC values convert
to decimal temperatures in ºF, or skip over them, and these can not be set by
the program.
4. After the system has been on for awhile, the temperature alarm sounds...
Make sure the LED temperature is at or above your preset alarm temperature
(default is 55ºC, 131ºF). If not, the audio alarm may be emanating from another
location, such as your motherboard’s BIOS alarm or video card. The Koolance
LED temperature will flash whenever the cooling system alarm sounds.
If the alarm is produced by the Koolance unit and the LED temperature has
not reached the alarm preset, please contact our technical department.
Also verify that the pump is operating (see Troubleshooting #1), and that liquid
movement is present in the reservoir. If the reservoir has been over-filled,
Troubleshooting
this procedure may not be possible since there will be no visible air gap.
5. My system has boot-up problems, or does not turn on...
Make sure the Relay Jumper is set to “NO” (Normally Open) on the rear of the
unit. (See: “Relay Jumper” for details.)
If this does not solve the issue, it is unrelated to the Koolance unit. 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.
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.
