Lately my liquid cooling system has been very noisy, I can hear it pumping the coolant, it gets louder and then quieter. Looking at it though I can see air bubbles in the coolant lines and I notice that instead of coolant moving in one direction(in one tube back out thru another) it's going back and forth in tubes - is this how its supposed to move? And the noise corresponds with the coolant flow - any ideas?? The CPu is not overheating the temp gauges are reading normal. I worry about the air bubbles - if air can get in can coolant get out????
do you have a res? or is your loop just pump to rad to block and back? if you have a res the air in the lines should be coming out in there. but if you dont and you have air in the lines it can kill your pump pretty quickly.
