Efficient cooling and simple installation
It's all in the title, though: make sure you configure your BIOS correctly!
The manufacturer instructs you to connect the radiator fan power cables to the 4-pin header on the CPU (usually called CPU_FAN1) and the pump power cable to one of the 3-pin headers on the chassis (usually called CHA_FAN1 or CHA_FAN2, etc).
However, these are often set by default to adaptive speed (speed according to the temperature of the motherboard) and this is absolutely the wrong setting!
Make sure you set the speed to maximum, otherwise the processor will heat up and the system will shut down.
Hope this helps :)
