google上搜到两个讲的比较详细的讨论，我推断是x1400显卡的散热有问题

回复如下：
Hello,
I think I have (had) the same problem like you do, but when you take a closer look, you will notice, that the only part which needs cooling is the gpu, even if you throttle it down to minimum. In other forums I read that this problem does not necessarily occur on every T60. Maybe the cooling units are not build in correctly. Fixing that problem could maybe reduce the length and intensity of your fan noise.
For me, the solution is simply to return the computer to the retailer and buy a more silent one. Otherwise I could never use my laptop in the library - what am I saying: I could not even work elsewhere. My cooling unit is so loud (and turns on and off every 3 minutes) that working or learning with this machine is really hard.
Good luck to you guys, cu
P.S.: The Lenovo Support told me, that the fan noise cannot be stopped, and that the loudness only arises from my sujective sensation. - Thank, you Lenovo - that made my decision very simple.
