View Full Version : Temps on north bridge.

10-18-2012, 03:23 PM
So, i just talked to a buddy of mine and he said that since i changed out my heatsink and fan on my cpu that i might be overheating my board. The old fan blew air straight down to the board across a built in heatsink. the new one blows air out. I have the maximus v gene. What I'm wondering, i don't have an exact picture right now but, the heatsink bank the is a L-shape right by the cpu, should I worry about heat build-up there? Also, what should my north bridge tems be while gaming under full load? Ill try to get a picture of my build up soon.

Nope you should be good to go, the air flow is still moving up and out via the 120mm exhaust fan. It is only when you go to a closed loop or custom water cooled loop that air flow, or rather the lack of air flow, can be an issue.

What is your mobo, pyro_m4n?

Z. he have the gene ( said so in his sentance :P )

That's what I understood too... but then where is the North Bridge? I thought, it's built in the CPU...

The OP maybe is asking about the VRM heatsinks? I found very benefic having a fan blowing directly on them... but when all is in a closed case, a good exhaust fan above them (top) is very good too...

NB is the the VRM
you have a north bridge and a south bridge.
just think, north = up, and south = down :)
green = north bridge, blue = south bridge.

Antec made this spot cooling fan on a flexible arm, if all else fails. Still needs cool air to spot cool with...

LOL, kkn, you've got a little confused about the North bridge...

The Picture you're showing is a Rampage III Extreme, if I recognize it correctly... that's a X58-based platform and yes, they do have a separate North Bridge - between the upper PCIe slot and CPU socket, here with the red heatsink on it...

The newer architectures does not have separate North Bridges... it was moved into the CPU... - like in hte mobos for Sandy Bridge, Sandy Bridge E and Ivy Bridge... but they do have VRM!

The black heatsink under your green line is the VRM = voltage regulator mosfets... it's doing totally different things than the North Bridge...

The systems with NB on the mobo does need a very good cooling of this chip (yes, it's a chip), in the newer systems the CPU cooler takes care of that...

Historically the NB managed the synchronisation between the processor and memory and the rest of the components. So all the USB, PCI and PCIe (VGA/Sound) would need to be meshed via a 'clock' before that data was processed.

With the majority of the NB function now being on die the concept of NB is redundant.

It is for that reason that in my original reply I did not mention specifically NB but used the term air flow. If you look at the two images above you will see what I mean about the historical function now being located on the processor.
