Koolance EX2-750SL - Manual (Page 28)

23 User Manual
Your Koolance system is designed to provide years of reliable cooling. To help avoid
unnecessary product returns, we have prepared this list of possible operational
problems, and their most common solutions.
1. How do I tell if the pumps are working?...
After inital air-fi ltering, the pumps may not create enough noise to tell if they’re
working properly. During normal operation, some air bubbles may even remain
attached to the insides of the hoses and will not appear to move when the
tubing is “fl icked”.
The easiest way to test pump operations is to simply monitor liquid inside the
reservoir. If the pumps are operating, liquid movement should be visible.
2. My temperatures seem too high...
Unless your processor is capable of reading temperatures within the die,
BIOS temperatures may not provide reliable readings for liquid cooling
systems. This is due to the absence of air fl ow beneath the CPU socket. If the
system exhibits signs of high temperature (reboots, shut-downs, etc.), there
may be a problem with your system. These same symptoms can also be
attributed to a faulty power supply, and other internal hardware.
Verify that the liquid coolers are making suffi cient contact with each component.
Make sure the CPU tension screw is placed in the correct cooler receptacle
(see the CPU Cooler’s Instructions). If the thermal interface material has
become over-used, or if the protective fi lm on a liquid cooler has not been
removed, the system can exhibit higher temperatures or malfunction.
Also check that there are no blocks, twists, or crimps in the tubing system. If a
nozzle has been attached inappropriately, it should be reconnected.
Finally, a dusty Radiator can also 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 whole centigrade units. Some ºC values
convert to decimal temperatures in ºF, or skip over them, and these can not
be set by the program.
