You probably aren't going to get any traction unless the T430s has the same problem.

If the T430s doesn't have this problem, we are officially screwed. Because there is no reason for Lenovo to care about us anymore.

My T420 has same problem. I just flashed BIOS, same problem. I guess Lenovo don't really care about us. This problem was noticed over a year. I don't think they are going to fix it. I will call them tomorrow, hope they could pay the return shipping.

Re: T420s Fan noise Issue

2012-04-24, 9:05 AM

Hi all,

 

after using TPFancontrol for the last 8 months my fan started to make very scratchy noises when it ran on 2K revs. So I finally called local Lenovo support and asked for a replacement. Without asking any question (!), the they came over and replaced the fan. While doing so, the technican mentioned that the fan on the T420s is one of the biggest problems and that a new model is used nowadays.

 

Ever since replacing the fan the maschine runs perfectly quiet! Finally! Should have done that so much earlier!

 

So: Given that Lenovo did not ask a single question (!) and replaced the fan immideatly, I can only recommend everyone to do the same!!!

 

HTH!

I will probably try this also, as the noise is pretty annoying :)

How old is your T420s?

If there really is a new part number, we may have found new hope again. But to be honest, the last year made me quite pessimistic that there will be fix...

@ Lenovo & Mark_Lenovo: Is this the long awaited fix? When will the product recall start? :smileyvery-happy:

mycroft: Is the fan quieter even while running at 4000RPM?

@jmstruckman: No, it isn't. but it doesn't run on 4k constantly anymore. It runs on 3.5k from time to time, but that's much less noise (though still audible).

 

@mh420: The T420s is a 4174P4G. Or do you mean the part number of the fan? If so, how do I figure out this number?
