BFG nForce 680i SLI NB Chipset Fan

post #1 of 7
Thread Starter 
I just opened and installed this motherboard into my system and was wondering if the NB Chip on this board gets very hot without the fan attached to it. My board did not come with this NB Fan and I can't seem to find one to buy anywhere. If it is recommended to use active cooling on this NB Chipset, what fan would be the best to use and what is the best way to attach it? Thanks!

get pc wizard and check the NB temp to see what its at. If you have good airflow it will probably be fine without a fan. It looks like it has a pretty serious heatsink on it, so it should be ok. If its running hot and you need a fan, then i would look on newegg for an after market cooler for it.

I had the EVGA 680i SLI board, and the Northbridge can get hot, excessively so when overclocking.

Since you don't have the stock chipset cooling fan, I would recommend getting a small aftermarket fan and attaching it to the NB heatsink somehow. Make sure the air is moving directly through the small fins, as from my experiences, that is what cools it the best.

FrozenCPU has a wide selection to choose from.

EDIT: Here is an illustration:

Ideally, the air should be moving in one of these two directions:



You could also have the air moving towards the board, but the shape of the heatsink makes it harder to mount a fan in such a way.

So a 40x40x10mm fan attached to the heatsink by screwing or tying(string or bread tie?) it on will work ok? I do plan on overclocking, so I would assume that it would be best to use active cooling on the NB Chipset.

How does this Sunon look for this application?

You could probably use hot glue or a zip tie, as well. Just make sure it's on securely, with nothing obstructing the fan blades.

I'm not exactly sure what size fan will fit, but I would try and mount it below the cooler (furthest away from the CPU), as that is where the stock fan goes. You may want to take some measurements to be sure.

The higher the CFM the better (obviously), but any air moving through there should help.

The place to mount the original fan is actually on the opposite side of the CPU cooler. Since I am running an aftermarket CPU HSF that blows air down at the board, I think I will mount the fan where the original one is supposed to be and have it pulling air out of the heatsink and towards the video card. This should keep my airflow moving in the same direction.

Ah, I see that the stock fan is supposed to go underneath the NB heatsink. Sorry about that, I edited my post.

I think your idea is good. That's how I would do it.
