Hi all,

I just setup my new machine with a DFI LanParty SLI-DR, although I'm using an old PCI video card while I wait for my PCI express card. Anyway, in the BIOS it has adjustments you can make with respect to the fan speeds in the system. You can adjust the CPU fan speed, Fan 2 fan speed, and NB fan speed. CPU and Fan 2 are self-explanatory but what is NB fan. I saw nothing in the manual that defines NB and I see no fan connection on the motherboard labeled as NB. Any thoughts or ideas?

thanks.
 
It looks like this may be a tough one.

Does anyone know how DFI customer service is? Am I likely to get a reply if I ask them this question?

The whole idea behind this, is I want to have a quiet computer (slower fans) when I'm not gaming, and willing to have a noisier computer (fans at full) when I'm taxing the system when I'm gaming.

Thanks again.
 
NB = Northbridge

There should be a small heatsink with a fan on your MB, under this is the northbridge.

Wait for others to give a more technical definition. I cant remember exactly what it does right now.

EDIT: Northbridge- The northbridge transfers data between the CPU, system memory, AGP card, and southbridge chip.
 
on the DFI LanParty the Northbridge IS the NForce 4 chip, since it's a single chip solution. with the exception of the NForce3/4 series, almost all other chipsets are Northbridge/Southbridge sets. 2 Chips, with Northbridge handling the more bandwidth heavy communications, like CPU, memory, AGP, etc. and the southbridge handling older stuff, like the USB, PCI, onboard audio, etc.

With the NForce 3/4, since AMD moved the memory controller onto the CPU for the Athlon 64, NVidia combined the two chips together, I don't know if this has any real performance advantages, but it does seem to provide motherboard manufacturers a little more flexibility in the layout of the motherboards than before.

Under most circumstances, I don't think the NB will get that hot, and several MB makers just use passive heatsinks on their NB chips, but when you're overclocking, the chip can get pretty hot, and the fan will provide better cooling than just a passive heatsink.
 
actually it gets really warm! most idle around 40c or a bit above. And mine loads from 45-50. So its a hot ah heck. The fan only gets noticably loud when its spinning at like 6k+(goes up to 7k)
