ML350 G5 False fan redundancy alerts on reboot

I have a client with three identical ProLiant ML350 G5 servers running Windows Server 2003 (32bit).

Each time I reboot the servers, I get about 10-15 alerts from my HP Server Agents about the fans switching back and forth about not being redundant, than back to being redundant, etc...

The fans are fine, I have verified they all work, and have reseated them. I have tried Proliant Support packs, firmware maintenance CD updates, etc... but still get these alerts on a normal reboot. Anyone else see this happening? I only have this issue with this client and this model server. It's not a major problem, just a nuisance. My other clients run various generations of DL360s, DL380s, ML370s, etc...

Example message:
The system has detected the following event:

SNMP Trap: 6037

Date time: 02/16/2010 08:33:08 PM
Computer: R3D9
Source: Server Agents
Type: Warning
Category: (4)

A 'Fans Not Redundant' trap signifies that the fault tolerant fans are no longer in a redundant state.
