None that i would know of. As far as i know the fans are controlled by thermo-sensors which kick them up when the system gets (too) hot and slower them once the temperature lowers.

You might try connecting to the service processor port and look at the ASMI. In case the system is not connected to a HMC: you need a web browser on the system you connect with and a crossover network cable to connect your system to it (i use a small netbook with Linux for such purposes). You have to configure an IP address out of the address range the interface is configured with (defaults are 169.254.2.147, 169.254.3.147, 169.254.2.146 and 169.254.3.146, see the
IBM documentation.
You will find something in the logs there, even when the orange LED has been cleared - if there was anything, to begin with. To me it sounds like one of these thermo-sensors might be broken/somehow dysfunctional, in this case only the hardware support can help. (You *do* have a hardware support contract, don't you?)
I hope this helps.

avahi-autoipd
avahi-autoipd(8) System Manager's Manual avahi-autoipd(8)
NAME
avahi-autoipd - IPv4LL network address configuration daemon
SYNOPSIS
avahi-autoipd [options] interface
avahi-autoipd --kill interface
avahi-autoipd --refresh interface
avahi-autoipd --check interface
DESCRIPTION
avahi-autoipd implements IPv4LL, "Dynamic Configuration of IPv4 Link-Local Addresses" (IETF RFC3927), a protocol for automatic IP address
configuration from the link-local 169.254.0.0/16 range without the need for a central server. It is primarily intended to be used in ad-hoc
networks which lack a DHCP server.
IPv4LL is part of the Zeroconf stack.
avahi-autoipd can be used as stand-alone address allocator or as plugin for a DHCP client such as ISC's dhclient, where it can be used as
fallback solution if no DHCP server is found.
To allow communication between hosts that have only an IPv4LL address assigned and hosts that only have a routable IP address assigned you
may add the following routes to both network configurations:
route add -net 169.254.0.0 netmask 255.255.0.0 dev eth0 metric 99
route add default dev eth0 metric 99
See http://developer.apple.com/qa/qa2004/qa1357.html for more information.
OPTIONS
-D | --daemonize
Daemonize after startup. Implies --syslog.
-k | --kill
Kill an already running avahi-autoipd on the specified network interface. (Equivalent to sending a SIGTERM)
-r | --refresh
Tell an already running avahi-autoipd to re-announce the acquired IP address on the specified network interface. (Equivalent to
sending a SIGHUP)
-c | --check
Return 0 as return code if avahi-autoipd is already running for the specified network interface.
-s | --syslog
Log to syslog instead of STDERR. Implied by --daemonize.
--debug
Enable verbose mode.
--no-drop-root
Don't drop root privileges after startup. We recommend not to use this option.
--no-chroot
Don't chroot(2) the daemon. This option is only available when compiled with chroot() support.
-S | --start=
Try to acquire the specified IP address, which must be from the IPv4LL range 169.254.0.0/16.
-w | --wait
Wait until a IP address has been successfully acquired before detaching. Only valid in combination with --daemonize.
--force-bind
Acquire an IPv4LL address, even if a routable address has been configured on the interface.
--no-proc-title
Don't change the process name while running. Unless this option is specified avahi-autoipd will reflect its current state and the IP
address in the process title.
-h | --help
Show help.
-v | --version
Show version information.
FILES
/home/lennart/tmp/avahi/etc/avahi/avahi-autoipd.action: the script to run when an IP address as been acquired or is lost.
SIGNALS
SIGINT, SIGTERM: avahi-autoipd will shutdown. (Same as --kill)
SIGHUP: avahi-autoipd will re-announce the acquired IP address. (Same as --refresh)
