    Default my fan won't turn off

    Hi,

    I recently have a problem with the fan. It keeps running at low noise even though I hardly do any hard processing (only browsing). I did try lowering the CPU to lowest, but it didn't work.

    ah thanks for the links
    I assume that it affected all thinkpad models... worse luck on t series that additionally have acceleration problems

    I think my fan might always be on, but at the lowest setting, I find that I can't hear it, so I don't mind much. Anything even slightly higher, though, and there's a ridiculous amount of motor noise that I find seriously irritating.

    I wouldn't mind if all I was hearing was air movement, but I'm pretty sure that most of the noise is from the fan itself, which is really unacceptable.

    Has anyone tried replacing the fan? If so, which fans are the best replacement for the cost?

    How about the T43 models? Same fan noise?

    The T43 models are supposed to be much worse than the T42s in that respect. The Sonoma platform runs hotter (CPU, chipset, and video card in particular, I believe), so I gather that the fan runs constantly, and at a higher speed. There are quite a few complaints over at thinkpads.com.

    My T42's fan also seems to be on for the most part, even when I'm just browsing. However, I've found that undervolting cools the processor down somewhat, and it takes longer for the fan to come on, though when it does turn on, it's very hard to get it to stop, unless I open the windows in my room and the room temperature goes down to less than 68F. Then, the fan will turn on/off intermittently. Unfortunately, the link above seems to be useful only on Linux, though I'm sure some enthusiastic person will eventually discover something similar for Windows.

    i found out how to turn off the fan.. unplug the battery adapter! i believe that the adapter made some part inside the laptop hotter.
