"fan error" possibly resulting from "linux-firmware-20110201-1"

So I did a clyde -Qu and then a clyde -Syu last night, it had upgraded linux-firmware to linux-firmware-20110201-1. A short while later my Thinkpad T510 started to get hotter and then did a surprise poweroff. I then tried to boot up again but after the thinkpad boot screen I got "fan error" then 2 beeps and poweroff. I tried this several time letting my computer cool down.

I remembered that I had recently upgraded the firmware so I booted up with a partition magic live usb, mounted everything to a directory (/media/arch)

mount /dev/sda5 /media/arch
mount /dev/sda7 /media/arch/home
mount /dev/sda3 /media/arch/boot
mount -o bind /dev /media/arch/dev
mount -t proc none /media/arch/proc
mount -t sysfs none /media/arch/sys
chroot /media/arch /bin/bash

Then I downgraded linux-firmware:

cd /var/cache/pacman/pkg
clyde -U linux-firmware-20101108-1-any.pkg.tar.xz
exit
cd .. && umount -l arch

I rebooted and everything now works fine.

I don't know for sure that this was caused by the firmware update and that this was fixed by my downgrade but I think it is likely. I just thought I would give a heads up.

EDIT: There actually was a hardware problem.
