Doing a build: ASUS P8Z68-V Pro GEN3 / i7 2700k Planning to run it at 4.5G's 24/7; however, wanting to play with it at over 5G's - Which H2O cooler? The tried and trued Thermaltake Water 2.0 Extreme or newer Corsair H100i. I've read that the Corsair H100i still has problems with Pump Rattle which can be fixed with a Resistor in the 12v Power lead to lower Voltage. It has new flexible hoses with a manual fan control on the pump Vs Thermaltake's USB Fan Control Software. Input from Anyone with experience on these products will be appreciated. They are priced somewhat similar - Then there is the Nzxt Kraken X60. What do you think?
