Koolance RM2-4U - Manual (Page 50)

45 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. How do I tell if the pumps are working?...
After inital air-filtering, 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 “flicked”.
The easiest way to test pump operations is to simply monitor liquid inside
the reservoir. If the pumps are operating, liquid flow will be visible.
2. My temperatures seem too high...
Since BIOS temperatures can not always be relied upon to give accurate
readings for liquid cooling systems, “overheating” problems are difficult to
diagnose. 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 sufficient contact with each
component. Make sure the CPU tension screw is placed in the correct
cooler receptacle (see CPU Cooler).
If the thermal interface material has become over-used, or if the protective
film on the CPU has not been removed, the CPU can exhibit higher
temperatures than normal.
Also check that there are no blocks, twists, or crimps in the tubing
system. If a nozzle has been clamped inappropriately, it should be redone.
3. 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 Control Board (or Exos Slot
Interface Adapter). Verify that all appropriate plugins are attached, particu-
larly the 12V 4-pin power supply connection.
