    In case you don't know or don't think it's relevant for you... "Undervolting" could lower your CPU temperature by 5-20 degrees on maximum load. This is no news and nicely explained in The "Undervolting" Guide by flipfire.

    I am just reminding you, it's worth trying out. Don't write it off as something that probably won't fix your heat issues. It just might do that :)

    I just did it on my new XPS16 (2.8GHz) and I managed to lower the CPU Voltage ID (VID) from the default 1.250v to a stable 1.0375v! On maximum load (for 10 minutes) the CPU temp dropped from 89 degrees to 72 degrees! And it stays there while on 100% CPU load. I then put the laptop on a passive cooling stand and it dropped to 68 degrees. 68 degrees with this laptop on 100% load... That's great! And all the other areas monitored by sensors in the laptop also dropped considerably. All in all, a cooler laptop with NO disadvantages other than launching a utility on startup.

    The utility used for this is a godsent (RightMark CPU Clock/Power Utility). Give it a try and help reduce the heat complaints on this board ;)

    Btw. this was done running Win7 64bit on my XPS16.

    And this post is merely to help people who haven't found The "Undervolting" Guide thread yet.

    Under volting really is a good way to cool the laptop. In a perfect world, it would be done at the manufacturing plant... but there are so many variables. I wonder how low you could get your temps with a Zalman 2000 cooler.


    Also... how do you like your screen? Seems like a lot of people are saying the colors bother them but people rarely post if they like something...
    EDIT: Never mind, I remember your post about adjusting colors to acceptable levels.
    Do you think it looks better than a Wled screen after adjusting?
