Precision T5600 fan speed after BIOS update

After updating to the latest BIOS A18 the fan noise on my T5600 has increased significantly. Front "pci" fan is now running at 1800 rpm while the front "mem" fans are at 800 rpm. BIOS fan control is set to "auto". Prior to the BIOS update the chassis was darn near silent.

Any suggestions other than rolling back to a previous BIOS version?
