    Anyone else experiences the fan is literally always on, regardless of the chosen power plan/settings?

    Right now CPU is at 25-26 C, and I can still hear the fan rumbling. I thought it may be the new BIOS that I flashed (since ThinkVantage suggested it) but now I flashed 1 version back (no idea what was the BIOS that came with it, any leads?) and it's the same problem. I don't remember it being always on the first day I got it.

    Any suggestions?

    I'd prefer not to install an external fan control software.

    nope i don't have this problem running vista, win 7 or xp on either of my two X200. What bios firmware version are you using? you can check it under the BIOS menu.

    I tried 3 versions:

    The latest: 3.15 BIOS / 1.06 ECP
    Original: 3.11 BIOS / 1.06 ECP (I think it came with this one)
    Older one: 3.10 BIOS / 1.04 ECP

    and no luck. :( Which one are you using?

    Tried 3.14, didn't help either... Trying Win7 reinstall now... no idea what else. Laptop doesn't seem warm anywhere.

    EDIT: Windows Install just restarted superfast (SSD FTW?) and the fan went off! Ah the blessed silence! Yay :)
    EDIT2: Oh and thanks for help ofc!
