Liquide cooling

I want to buy Thermaltake Big Water 745 to cool my e6850 and my south and northbridge of my nforce 680i LT motherboard. Can anyone tell me if that kit will be enought to cool down cpu and chipsets..?? If yes then what wather block to use on southbridge as it is under graphic card.

What motherboard do you have? The Thermaltake kits are not renowned for their best performance, have you looked into a custom kit, could work out cheaper aswell.

As for the Northbridge, the Swiftech MCW30 is a good block and is cheap aswell from overclockers. Just make sure the ID of the barbs match up to the pipe size and to the rest of the watercooling gear.

To be honest it is unlikely your southbridge will warrent watercooling, does it have a temp probe there if so what are the temps? Highly doubt it will be getting hot enough especially with the active cooling you have on there atm, oh and good luck getting a block on there with that gfx card

my motherboard is XFX Nforce 680i LT SLI. And trust me when i overvoltage nortbridge it gets so hot that fan speeds up to 5000rpm and its showing 70 deegrees C and radiator is boiling hot when i touch it.!! But as for northbreadge I can use any water block as it is easy to access

I'm confused, isnt the 2nd picture of the northbridge and not in-line with your graphics card and the first picture is your southbridge?

Swiftech MCW30 is ok to cool northbridge but not southbridge as it is under graphic card

red lines shows graphic card. Between chip and graphic card there is like 16mm space.

So i need something like that

water block is slim and water tubes are on the bottom.

i'm not sure. look on that picture

on that picture it says NB northbridge?? on top fan so one on the bottom must be southbridge..??

z10m · 2 Jan 2009 at 11:51

so yes second picture is of the northbridge and first is southbridge. i want to water cool both..

both fans are very loud and southbridge fan is louder than anything in my PC..

You are more or less forced to water cool your graphics card as well if you want to put a water block on the SB, just to remove the bulk of the gcard air cooler, and even then it can be tight. I would forget about water cooling the SB tbh. I know when I speced my water cooling set up I was the same, I bought a block for everything but in the end I decided to just stick a zalman on the SB as the extra tubing and hassle avoiding the gcard just wasn't worth the minimal benefit of water cooling the sb. If the nvidia chipset is anything like the X38 then the SB has little effect on overclocking potential and doesn't generate that much heat compared to the NB.

You really dont need to water cool the south bridge, it just doesn't get hot enough.

z10m · 2 Jan 2009 at 12:41

yes but that small fan is very loud it's the loudest thing in my case.! and i want water cooling to make things quiet.. when im overclocking and overvoltaging it gets up to 65 degrees C on full fan speed and the noise it produces is very very annoying.

there is not enought space to put passive chipset cooler..

ok so thats what I just did.

I found old zalman chipset cooler
i broke off some of it so it fits under graphic card

and thats the resoult without overclocking in system idle with case open.

you guys said that southbridge wont get too hot well mine do..

Point a fan at it then. If you insist on using your sb block I think you would still have to also water cool your graphics card, cos looking at the orientation of the sb holes, and the holes on your pic of your sb block, it looks to me as though the ports would still foul you gcard with its stock cooler on. If I interpret it correctly the two ports would lie vertically, inline with your ram slots, so one of them us going to clash with the card. I say this as the pin holes on your existing sb sink look like they match the holes "which are not on the extreme corners of the block in the pic" for want of a better description.

yes i want to water cool graphic card as well. As for now i pointed big quiet fan at the cooler that i installed and that lowered the temperature to 45 wich is a lot less than with that small noisy fan that was there before.
Going back to water cooling what do you think about Zalman Reserator1 v2 ??
