Just thought I'd point this out for anyone that hasn't thought of this, or didn't know it was possible.
I have an E1705 with a T2400 Core Duo (Yonah) 1.83Ghz CPU. As this thing goes along, it seems that perhaps dust or something has made the temps rise a bit. Before last night I was idling in mid-high 40's (Celcuis) and saw loads as high as 70's! I thought that was a bit much. So with the aide of Notebook Hardware Control (http://www.pbus-167.com/), I lowered the voltage of the CPU from the stock 1.2625v @ 1.83Ghz, to 0.9750v @ 1.83Ghz. The lowest option is 0.95v, but I couldn't run at that voltage.
So as soon as that program loads on startup, my voltage is dropped and the temps are SIGNIFICANTLY reduced. I idle at 35c and load at 56c. The fan never goes above low, so it remains quiet.
When you try it, the NHC program will run a quick test for stability before setting the voltage. I'd recommend running Orthos Prime (http://sp2004.fre3.com/beta/beta2.htm) for a while to make sure it's totally stable
I also use I8kfanGUI (Dell Inspiron/Latitude/Precision fan control utility) (http://www.diefer.de/i8kfan/index.html) to control the fan speeds. (So I can keep the GPU temps from getting out of control) You can set custom temp settings which will enable either or both system fans. And you can set them to Off, Low, or High based on temps determined by you.
It'll monitor temps of CPU, GPU, Memory, Chipset, and Harddrive(s)
Another great use of this is to run your CPU at full speed while on battery, but consume a lot less juice. My notebook cuts the CPU speed in half when I unplug it. But with NHC, I can now run it at full speed but not use much more power doing so.
You can also create seperate power profiles depending on whether you are plugged in or on battery. So you could have it step the clocks down on battery if you chose to.
So I just wanted to point out this great way to lower temps. I'd imagine it'll work for most any Core Duo/Core2 Duo CPU's ....and perhaps others as well.
