I purchased an FX-8150 processor with the liquid cooling kit that is similar to the Antec Kuhler 920. It has a 3-pin motherboard connector, and two 4-pin connectors for the fans to plug into, as well as a USB connector and Windows-based software to control the fans. I'm installing it into an Asus M5A88-M motherboard, and running VMWare ESXi 5.1. As such I have no operating system that can control the fan speeds on the liquid cooler, since virtual machines don't have direct access to the motherboard. The fans always run at low speed and they don't speed up when the CPU temps rise. I'm considering plugging the two 120mm fans into the CPU fan header using a 4-pin splitter, which would allow the motherboard to control the fan speeds. I'm also considering connecting the 3-pin power connector for the pump to my power supply, using a molex-to-3-pin power adapter so the pump has full power at all times. Please tell me if this configuration will work properly and, if so, should I still plug in the USB connector?
Another possible solution: Is there any combination of enabling/disabling “Cool&Quiet” or Q-Fan that would result in the motherboard controlling fan speeds, and saving me from having to introduce a bunch of power splitters/adapters? I tried a couple variations, but none seemed to work.
