Part of the causes of these fan errors must be due to a unit sitting powered off for a extended period of time (Days/Weeks)
We had 6-8 fan failure tickets come into us this morning.
Thankfully all but one responded to the BIOS flash.

Add me to the list of people being greeted by "Fan Error" on boot. Just happend today for the first time. I was able to get things going again by blowing compressed air into the exhaust outlets. Rather large plume of dust came out and now system seems to be behaving normally.
I will confess to running a distributed computing application over night while the unit is idle. While CPU usage is restricted to 25% max this still seems to heat the unit up quite a bit.
While I wouldn't go so far as to call the part "defective" I will say that the T43p I still have as a backup hasn't had any issues and that thing is old as dirt. Doesn't seem like a great idea to have the fan exhaust blow right into the docking station on these T400s, though.
Just got upgraded this Monday at work to a T420. Imagine this issue has long been resolved...I hope.
Thinking I might buy a new fan unit, just in case, before parts are no longer available.

Yes we're finding the BIOS udpate is only a temporary fix.
We're still having clean fans come back up with fan errors.
If you havn't already, remove your keyboard and hit the fan with compressed air to blow out any dust.
If your under warranty call Lenovo to have it replaced.
If your out of warranty and you have the older model fan (FRU # 45M2722 ) prod Lenovo to have it replaced under warranty anyways. They discontinued that fan model back in May/June of last year and replaced it with FRU # 45M2724. To date I think we've had 1 of the 45M2724 model fans fail on us. The 45M2722 model might as well be a ticking timebomb for what it's worth.

I would not be surprised!
How many posts on the internet have you read about CPU fans on the T410 Thinkpad running at full speed during normal use?
I happen to have purchased a Thinkpad on ebay, the fan also blast’s away at full speed during normal use. My predictions
are that this machine will suffer from a fan failure at some point. Updating the BIOS and trying various settings with the Lenovo power management has been very unsuccessful.
LENOVO NEED TO GET A GRIP.
No longer are people going to pay over odds for a laptop that just does not live up to expectations. As a starter my Toshiba Celeron laptop cost under £350 new, the LCD screen is mile’s better than my previous Thinkpad T500 and my newly acquired T410 , it also and runs quieter. My T410 has a corner where the plastic is crumbling away, **bleep** !
This is a laptop that Lenovo promote as semi rugged ( Clever marketing, don’t believe the hype )
I for one are finished with Lenovo Thinkpad’s . My next purchase will most likely be a Macbook Pro.
LENOVO, I AM VERY DISSAPOINTED WITH YOUR EXPENSIVE CRAPWARE.
