View Full Version : Worth WCing the NB???
So I am still working on my WCing setup and wanted to know if it was really worth it to cool the NB. The CPU and GPU are obviously worth it, but I'm not so sure that the NB will benefit all that much from it. I'm already at 220 with the stock cooler.
I know a lot of people cool their NB, but do any of you see any more performance from doing so?
The fans and sinks that come with the motherboard are only rated to take so much, and when changing how you want your pc to perform it eventually comes to a point where you need to change that cooling.
Things can take more when they state at a cooling point below what they were at before. Cooler tempatures means higher performance.
Ok, but after going though a hot CPU and GPU will the NB be getting any extra cooling?

The water temp doesn't change much going through the loop. Typically it is less than 1-1.5C difference between the high and low water temps.

Hot hot does the NB get on an NF7-S? I've touched the NB cooler and it is warm to the touch, but not like my SLk-900 on the CPU or the Silencer on the VGA.

There was a poll on this a while back, here a link http://www.ocforums.com/showthread.php?s=&threadid=247864. I dont mean to revive a dead thread, but it has the answer, most people think its overkill. (thanks)
i would reccomend a swiftech northbridge heatsink. it costs less than some nb blocks, it wont hurt flow rate, it wont cause more bending and pressure on the tubing, and it will provide excellent cooling.
edit: and its only 18db at 12v -silent enough for me, but would be even quieter at 7v

its only overkill in some cases. It really depends on your motherboard and how high u can overclock ur cpu.
With a passive heatsink, my epox wouldn't get over 180fsb, which sucked. even at 180, it would get really hot and sometimes, during summer it would be unstable. When i watercooled it, i would get 200fsb stable even in summer.
So, u gotta do more testing... try puting a larger heatsink on your NB with a fan and do some tests, if you've already reached the limit of ur motherboard then its pointless to buy a NB block. If you're annoyed by that little 40mm screamer fan on your NB, then that would be another reason to invest in a NB block.
Keep in mind, when u upgrade, that block is probably not going to fit on a 64bit mobo and i have a feeling they won't be making adapters for it so only get it when u're sure its going to make a difference thats worth while.
So do you lap your NB before you cool it to the point that you can see copper?

since you are running a nf7-s Definately cool your NB to get a better oc
in fact if you have an uber pump or a 2 pump system you can cool your NB and HD and psu and if you got some real skills ,make a custom block for your SB ( very hard to attach but im working on a way to do it)

My friends and I experimented, we were able to OC higher with the OC watercooled...

lap the north bridge? I dont think your supposed to sand micro chips like that.

I lapped the NB on my ASUS A7N8X until I had a nice shiny copper circle. That along with doing a vdimm mod helped me go from 180FSB to 220FSB stable. This was on the first nforce2 chipset, so 333 was supposed to be the max.
On the new nforce2 ultra 400 chips is there still a copper plate or if you sand too much will you hit the core?

actualy in standard IC like that ints not a problem as the layer of ceramic is very thick and you can tame more than 1mm off it and still not reach any circuits.
i lapped my south bridge to near flattness as well with no problems taking about .5 of a mill off it before it was flat.
