GRID K2 Fan Noise Exremely Loud

I just bought a new GRID K2 card (900-52055-0030-000) with 2 fans attached to the card. These little fans are Extremely noisy 9with no system load), I am using them in Xenserver 6.2. Is there a way to slow them down, or have them vary the speed according to temperature.

The K2 with active cooling is designed for data center use and is expecting to be under load so the fans are set to max. Keep in mind that the K2 is two Quadro K5000 equivalents on a single board, and we added active cooling for chassis that could not otherwise support (properly cool) a passive K2.
