South Bridge For a nvidia 680i MB.

post #1 of 21
Thread Starter 
I know, its not really necessary to wc your motherboard, but I already have a wb for my north bridge. Only problem I have its that my motherboard southbridge and northbridge are connect together by a heat pipe. So i need something to add to my sb, cannot be too big because otherwise will be impossible to fit my first video card. So I found this: http://www.performance-pcs.com/catal...ducts_id=22241

here is a example of the mb:

so will that little fan will be good enought for the sb?

Thanks...

Hey Made, I haven't used one of those but it doesn't look bad...

I used one of these on my SB and its decent..Enzotech SLF-1 ...I don't know if it would fit your mobo or not, but they are universal fit....

Here are a couple of pic's so you can see the height...

Those are the SB coolers on the XFX 680i sli LT which is what I have. It works fine until you hit 1.5v. I guess if you put some other thermal paste on it would might be able to go to 1.5 without errors. It will do the job just fine but my thinking is if you are gonna put something on that you are gonna be overclocking with to use something really good. personally i would use the enzotech heatsink and just put a fan somewhere near it. That fan you linked to does do the job though.

The SB (MCP) default is 1.5v and doesnt need to be increased. It controls the 3rd PCI-E slot as well as the SATA, RAID, LAN, Audio, etc.

The Thermalright HR-05-SLI works great on the SB. I ran mine without a fan and the MCP temps stayed at 36C:



Here is the heatsink on it's own:

both 680i and 780i can 3-way sli.

yea the little fan is good enough, but i would personally put it on water just because it looks nice and those small fans are a waste of time. unless like other suggested you want to go with a larger passive cooling solution. i like what ira-k suggested (copper lovers) low profile and quite nice to look at. but if you want a wc solution for 24 bucks you can get a mcw30 i got mine for 22, so i picked up 2, put one on my GFs rig on the NB just for kicks and have one laying around.

it wont effect your temps all that much, maybe a few degrees nothing to worry about. and you have to admit it does look good with all the blocks on a loop.

I really wouldn't recommed doing it but if you must watercool it the following fit:

EK NF4 Rev1.1 (need to cut the bolts down to length though)
Swiftech MCW-30

I know this as I have watercooled 2 680's and tried both blocks!

EK Block




Swiftech Block

I used a Danger Den MPC-Universal, although I would recommend the brass top version, it's a lower profile which you need to get under the video card.

I had to modify this one a little:





But if you just wanted to go with air, the thermalright HR-05 SLI did a pretty good job with an 80mm fan on it.

The northbridge is the hot one in comparison.
