Liquid cooling - testing and repair?
Posted on 2011-02-27
I recently purchased a Cyberpower Gamer Ultra 7500
This included the XtremeGear Liquid Cooling System 120MM system (Xtremegear has the same address as Cyberpower, so I assume it's an in-house brand).
Because of a busy life, I didn't put it into service for 3 weeks, the computer worked fine for the first week after that, then I started experiencing sudden shutdowns, coming more and more often. I called Cyberpower tech support, and they thought it was a PSU issue. At first they offered to cross-ship, but then called me back to let me know it was more than 30 days from purchase, so they would not cross-ship. I purchased a Corsair PSU, and installed it... but the shutdowns continue.
So, I installed SpeedFan to monitor temps, and saw that my core temp and another temp were going above 100C, then the machine shut down. So, I figure my liquid cooling isn't working... I popped the cover, and while the tubes where attached to the pump get quite warm (and the pump glows blue), the tubes inches away at the radiator stay cool. Core temp and other temp climbed steadily on SpeedFan's chart (this time I shut down manually before it passed 85C).
Anyone know how to diagnose the Xtremegear liquid cooling? Radiator fan is running, I cannot tell if the pump is running or not, but it seems that no liquid is being circulated.
