Ok, I searched the forums but couldn't find my answer anywhere.
I bought a MSI 6990 for $550 off some guy. (yes it works lol)
Well I plan on watercooling it. I already have my AMD X6 1100T water cooled but I am unsure on how much this loop is going to work.
I have my AMD cpu on a 240mm rad. It works very well. The cpu only puts out about 150w so the 240mm cools it very well.
Now my project for this watercooling loop is to use the 140mm back fan port to install a 140mm with the 6990 on it's own loop with it.
My question is will a 140mm with a 70cfm fan cool this monster?
Parts I ordered:
1 x Black Ice® GTS Gen Two Stealth 140 Highest Performance Radiator (GTS140) = $64.95
Fitting Size 1/2" Barb for 1/2" ID tube
1 x Alphacool NexXxoS ATXP Back Plate - ATI 6990 Series (11031) = $22.99
1 x Alphacool NexXxoS ATXP ATI 6990 Series (11028) = $120.99
Fitting Size 1/2" Barb for 1/2" ID tube
1 x Koolance Reservoir and Pump, RP-980BK, Black [no nozzles] (RP-980BK) = $138.99
Nozzles Add Nozzle Pair, G1/4 Barb [13mm, 1/2"] NZL-V13KGB
I have the koolance combo pump and rez already for my CPU so I got a second one to match it.
Anyone happen to know what kind of Wattage these rads are designed to cool? i read the 6990 uses 470watts of power...
PS: added most of my Rig to my profile. will add more once i get all these new parts put in

essentailly 1 360 rad cooling down a 6990 and AMD processor, i wouldnt recommend that, even at low rpms, i only know of ONE guy who did something similar to what you are doing except he was using an rx 360 and ultra high rpm fans cooling 2 x gtx 580's and an i7 950 oced. your temperatures will be phenomenal (the bad way) and wont be of ANY decrease, in fact maybe a increase..., if you want good 'slim' radiators optimised for low rpm fans, i suggest the new xspc ex series, for (this is my word for them 
) 'fat' radiators, something like a xspc RX series should suffice. may i also ask which pump you are using. if you wanna sufficiently cool the metling gpu's and cpu, i'd go with something that is AT LEAST 480 in total (e.g. 2 xspc ex 240 radiators). also this is a WONDERFUL tool to use, you should try it to find out your delta temperatures, restrictiveness etc.
