I left my computer for about 2 hrs...watching tv and stuff and I came back to see that there were 2 big air bubbles at the highest points after the pump and the pump didnt seem to be working. I immediately flicked off the psu and felt the tubes and they were really really hot. They seemed to bend more easily due to the temp. I plugged in the pump to a different molex connector (well, actually the same one as yesterday, i just switched them around because i installed a new IDE drive for vista). Anyway, now the tubes are clouded where the bubbles were and the chipset temp is at 50c idling at stock (using the air, not water). I have no idea what happened. Any thoughts?
