Not Sure if Water cooling is working

Processor Intel(R) Core(TM) i7 CPU 930 @ 2.80GHz
Memory (RAM) 8.00 GB
Graphics ATI Radeon HD 5800 Series
Liquid Cooling Asetek 510LC


I am having a current problem with my CPU overheating after playing newer games for 15-30 minutes. I am concerned that it may be a problem with my liquid cooling not working. Currently my CPU temp is at 48 degrees C when idle and when under a load it gets up to 60-68 degrees C and this is why my sound starts getting really crackly and then my computer just shuts off.

Is this a problem with my liquid cooling or is it something else?

FYI When I first bought my computer it would run around 30-40 degrees C at idle, not sure what it was at under load though.

Well I tried bleeding it out about half an hour ago. No success. So I'm going to go with the Hyper 212. Thank you for the suggestion the fan looks amazing and it's huge size will fit fine in my case.

Thank you for the help guys, all of you.
