    I have implemented experimental Fan Control in HWiNFO32 for some HP notebooks.
    It might work on other models too, but the condition currently is to have one of the:
    - SMSC EMC2113 (8740w)
    - SMSC EMC2103-1, EMC2103-2 (8530w)

    fan controllers.
    If there are other models with different SMSC controllers I could look if it's possible to add that control too (I'd need feedback which HP model it is and which SMSC sensor is detected there).

    The Fan Control is not a published feature so you need to do the following things to activate it:
    1. Open the Sensors window and make sure you see the SMSC sensor
    2. Click inside the list of sensors (make sure it has focus)
    3. Type on keyboard: "fancontrol"
    If you did everything correct and your machine features the supported SMSC sensor a small window should open. By default, the "Auto" mode should be selected. In this mode the fan speed is automatically controlled by the preset logic depending on temperature (look-up table). You need to switch to "Manual" mode and then you can change the fan speed and click "Set Speed".
    Watch fan speed in the Sensors window...
    Give feedback....
    Enjoy ;)

    Thanks Mumak! It's working great on my machine (8740w)
    Now, the system can handle the most intensive tasks w/o overheating! Whoa!
    HP default look-up table is great for those who never stresses the system much and want a silent fan.
    But it works not so perfect when running benchmarks and other demanding apps. I had 85C on Both CPU and GPU during Furmark and 3Dmark06. Now with the manual fan control, it never reaches 75C!

    Modifying of the look-up table might be a possible feature too, but later..

    Does it work for an envy 15?
    Can you make a screenshot what to do? because I don't know it, after reading...
    What is "SMSC sensor"? Is this just fanspeed?

    Thanks, glad people are still searching for such things, HP don't have to control MY notebook.
    You know some ways to change voltage @ gpu? or overclock an i7 720QM?

    Depends on sensor/fan controller used. Please post a screenshot of the Sensors screen.
    I'm sure Aikimox can post a screenshot of the process (I don't have such machine)..

    I hope it's possible... (fingers crossed)
    Is this only GPU fanspeed adjustment? or CPU too?
