Check 2 things.
1. Are your individual vent settings set to max cool air. I believe you can check these in the settings menu by pressing down the iDrive controller while at the main menu.

2. Are you pressing the Auto button located in the driver's side temp wheel? Rotating the temp to 60 degrees for both front occupants AND pressing the Auto button until the fan sensitivity is set to HARD will provide max cooling. If you press the Auto button repeatedly you'll find the display will show that you are changing between SOFT MEDIUM and HARD (Display may say INTENSE).
