For me this issue went away when I updated my bios. Do you have the most
recent version?

&gt; Hi everybody,<br>
&gt;<br>
&gt; I saw some people on the list using a T420s. I have one, and I have been<br>
&gt; experiencing excessive fan noise, due to a fan that never spins down<br>
&gt; from 4000 RPM.<br>
&gt;<br>

&gt;<br>
&gt; Is anyone of you seeing this? I am trying to figure out whether it is an<br>
&gt; hardware problem, hence I should ask for a new motherboard, or if a long<br>
&gt; requested BIOS update could solve it, in which case I&#39;ll continue<br>
&gt; pestering Lenovo.<br>
&gt;<br>
&gt; Thanks a lot,<br>
