4870x2 + Watercooling

well... I don't know how the 4870 X2 design compares to the 3870 X2... but all 3870 heatsinks work on 4870s.... so maybe a 3870 X2 full cover waterblock will work on a 4870 X2

do you even need anything on southbridge?

Did the 3870 have the bridge chip between the GPUs?

Hi i have 2 x ASUS 3870X2 in crossfirex.. i have one 240mm rad going into the cpu then out of cpu into a single 120mm rad then into card 1&2 my temps

CPU IDLE 37c LOAD 50c
GPU 1 IDLE 38c LOAD 52c
GPU2 IDLE 39c LOAD 55c


On air my E8400 Cpu idle was 48c this is running @4GHz and the GPU'S 50+ @ idle plus they sounded like jet motors under load... the only thing you should do is water cool the NB aswell due to running crossfie etc on a Asus rampage formula x48 my NB temp is 60c+ but still ok till 90c

Cant wait for some 4870x2's they look sweet but not sure on the performance increase, as the 3870x2 drivers have got better they run much faster now.. when i got my back on the release date i could only push them to 16300 3dmark06 score now with better drivers etc im hitting 22000 plus thats stock cards and 4GHz cpu ;-)

ok new to all of this but your message sounds like you could help me,
i have new pc, rampage formula x48, e8600, diamond 4870x2 card all in an antec 900 case with an ocz 850 watt gamextreme power supply.

i could use some good ideas on bios settings for overclocking, there are so many variables i just need somewhere to start and which ones are the most important in this bios for cpu and memory overclocking, oh, i have 2 x 2gb corsair pc8500 dominator memory, with the included memory cooling fan hooked up too.

but my main thing is that i want to look at water cooling the cpu, gpu and possibly nb... what should i use, what parts do i need, links if you could, and if you can kind of show me a picture of how the setup basically would look as far as what cooling parts in what order or what hooked to what... do the cooling fans, radiators, whatever all come with all of the connectors you need or do you have to figure out all of the connections on your own?

please anyone help if you can... live in the us,, and would me more than happy to email back and forth or whatever, or i can sport the phone bill for long distance to get this worked out, really want to get the right setup the first time and would like to get some stuff ordered... about how much would a decent water setup for this cost,, im hoping to get about 3 years out of this pc, at least so will want to push it eventually when i need to.
