I just got the Antec cooler installed and I must say Idle: 9C Load 36C that's awesome for the bottom end water cooler! its not loud at all I love it if your looking for a low end watercooler this thing rocks By the way I replaced the thermal compound with Artic Silver 5 and its a 4C difference so the thermal paste on their isn't bad at all I recommend this cooler to any new water coolers its almost plug and play
