    How low do you go when undervolting your w2v?

    I'm currently using NHC to undervolt the w2v. So far I've gotten down to 0.908v at 6x multiplier on AC, and 1.324v at 16x on AC. I'm kinda curious how low it can go and if others have successfully gotten it to be stable.

    Currently the temp is around 48-51 C at 6x, and around 62-78 C at 16x depending on the application.

    Also, anyone know if the fan can be replaced/modded? It seems the fan kicks on [and stays on] when the temp reaches ~41 C.

    At 6x I can run my Z33Ae at .700 on battery no problem, and at 15x I got it down to (amazingly) 1.100v even. Even ran Prime95 overnight to check it, on AC.

    The Z33Ae fan comes on at 45C and then it has a couple of speed steps as things get hotter. I wouldn't mess with it - at load the fan is the only difference between a fried CPU and a working one. The temperature changes in response to load relativly quickly, at least on the Z33Ae, so I think I'm going to trust ASUS in their thermal design and limit my modding to undervolting the CPU to reduce the heat input into the system.

    Today, I managed to lower mine to 0.700v at 6x and it maintains a temp of around 40-42 C on AC. I notice the fan on the w2v kicks on even if the temp is 34-37 C. It seems to kick on and stay on 1-2minutes after system bootup. =T

    So 0.700v @ 6x= 40-42 C temp, compared to ~50C when I had it at 0.924v.

    In terms of when running at 16x @ 1.212v on AC, I get temps around 58C, compared to the 67C of the original voltage. However, the temperature fluctuates to around 74 if I run intensive games (due to the X700 I guess).

    Right now I usually just have NHC run the cpu at 1.60ghz max on AC/battery since I haven't had any apps that required the full 2.13ghz yet. Everything's still smooth even @ 1.6

    You guys are lucky... I can only get 6x down to 0.716v and not 0.700v... and you guys have a faster processor :(

    I'm very impressed with the amount I was able to undervolt, actually. I think even the ULV processors run at higher voltages.
