Here I am again,
@JameZ: You now got each our MTM, S/N, etc... So what are the next steps, how are you going to proceed with our issue? What's the time frame for us to expect a solution?
Is this an actual Support Forum or do we have to get in touch with the Lenovo helpdesk/Support hotline to find a solution?
Thank you for advice.

Jamez can escalate issues directly as he is a Lenovo employee. Once he has enough information to define the problem clearly with steps to recreate and system specifics of model, OS, drivers, and BIOS level, he can either recreate himself or create / escalate the case.
Our senior technical team will work the case and validate the symptoms and then pass to engineering and development as needed to obtain root cause and provide an update through drivers / bios as needed.
It is difficult to say exactly how long this process will take - can vary based on complexity of the issue, but typical the engineering cycle is around 4 weeks. Sometimes faster, sometimes a bit longer.
Jamez often continues to collect information and receives updates from engineering .

after one week with my T420s I consider sending the unit back because of:
Can someone from Lenovo confirm both points and indicate a timeline for a solution
1. changing the fan to an appropriate model without whining noise
2. BIOS update which solves the fan behavoir
up to now I only bough consumer notebooks and this time I was willing to pay
the premium for a premium product - finally with a big dissapointment. lenovo
has to fix this very quick.

Ladies and Gentlemen, I found a temporary fix for our hair dryer issue.
There's a German guy who calls himself "troubadix" (the bard in Asterix) who developed an application to adjust the fan speed on ThinkPads. The application is called TPFancontrol. It's latest version is 0.62 and is set up for his T60.
The latest version can be found at troubadix page from uni-marburg right here.
Donations are welcome to him.
And below are the settings I use in the TPFancontrol.ini file to run my ThinkPad T420s quietly when on the go (passive until 50°C).
When docked in the Advanced mini 3 plus docking station and using two external monitors (1920x1200 + 1050x1680) the discrete graphics kicks in and the CPU is always near the 60°C mark. With the settings below you should be able to keep the temps around 60°C with moderate office work. The fan spins between 2900 and 3700 RPM.
I hope this helps. I wish you a great sunday.

some update from Lenovo? I've just got my T420 this week and I also find the fan really annoying... I am convinced that it is a hardware problem - a bad fan. I wouldn't even mind if it was a bit louder or constantly spinning...what gets on my nerves is the high-pitched noise.. like someone said, it is best compared to a hair dryer and it also makes me ponder returning it for a refund. In my opinion, a BIOS/driver "fix" would just delay the noise a bit (and shorten the life-span of the machine?), a better quality fan is what's needed. I guess the warranty would become void if one attempted to replace the fan himself?

ok, looking forward to a solution.
The noise clearly comes from the fan - it changes with the load of the machine and I tried it also with SSD only, no HDD or anything else that could make the noise (afaik). Perhaps one more note, I do *not* have the optimus version, mine is Intel HD Graphics only.

It is a hardware issue. The fan noise drives everybody nuts and I think
I am not the only one here who will return the unit because of this bad
Please come across with a straight forwards solution for your customers.
(replacing the fan & bios update for better fan control).
...I think we are waiting now to long.
