Hi eva2000,

wonder if you can help me confirm something. Can you tell me if your AI7's northbridge ever gets warm to the touch?

I'm running mine *passive* on two AI7 motherboards (without issue), one using the stock blue heatsink, the other a NB-1.

Even though neither of them is using a fan, they don't get warm?

I just picked up an ASUS P4C800-E deluxe, which uses a passive black heatsink and that gets *toasty* hot!?

I just need confirmation from another ABIT/INTEL user, many thanks!

yeah AI7 NB cool, my P4C800-E get alot hotter

Want to know why?

The AI7 keeps stock VDD unless you change it yourself.

ASUS' P4 boards scale the VDD according to the fsb.

Hi all,

thanks for your replies! I realised that I was using a stock P4 cooler on my ASUS P4C800-E (all I had spare when I recieved the mobo), whereas I normally use a SP-94 +92mm fan which of course lends some airflow to the northbridge, hehe silly me.

But now you say something about *VDD*. Hehe I don't think I know what VDD is? but good to know that there is something different on the ASUS.

VDD = chipset voltage

Hi,

Oh, but I don't think there is a VDD adjustment on any of the INTEl boards I own? though there is vAGP which is *supposed* to boost the voltage to the Northbridge?

Chipset - Northbridge = same?

eva2000

yeah chipset = northbridge loosely for P4 865PE/875P

So this means it safe to unplug the fan from my AI7 seeing that i have a 92mm fan blowing just above it?

I don't expect a reply. Kinda just talking to myself

The Intel forums these days are pretty empty. It's all A64 right now, i'm still counting my pennies to jump ship
