Will a 240mm and 200mm Rad be enough to cool Xfire R9290s

I have a Corsair 600t. This is the first cutom loop i've ever done so i dont have much to go on. My plan was to place a 240mm in the top, a 200mm in the front and if needed a 120mm in the back(although i'm not sure if that will fit without putting the fan on the outside). Summer is killing my 290s with them hitting 95c in Xfire even with the custom MSI twinFrozr fans at max. Also can anyone hazard a guess of temperatures i could expect. My Fx8350 would also be in this loop, but its not massively overclocked (4.3ghz bad OC chip) thanks

I suggest buying an air conditioner if you don't have one. No amount of radiators can cool it much further than ambient room temperature. And you wouldn't want your case insanely cool with the surrounding areas to be really hot and warm. You know what happens then right? Think about what happens to a ice cold water bottle sitting on a desk with the room being hot / warm. That's right, condensation. That would not be fun to happen inside a computer case.

I understand you cant get below ambient. But i want to get below 95c. I'm talking Celsius here not Fahrenheit. I'm British. lol, Temps in my room, even with windows open are hitting 28c at the moment. Also i have an air-con unit, but our windows are slightly different. You cant really window mount them so they have to be stood on the floor. Its very noisy and takes up alot of room.

Yes; I know it's in Celsius. That is the metric we use to measure temperature relating to computer components. In that case, I think one 240mm radiator would be sufficient. You can run two if you want. For having two radiators, make sure you have one of them as exhaust and one of them during intake so one of the radiators will be cooled by cool air entering the case. I also recommend some Noctua NF-F12 fans and use their low voltage adapters so they not only keep good air pressure through the radiators, but also be extremely quiet.

I already have decent fans GT1800s. Really 1x 240? I was under the impression 1 x block (eg gpu, cpu) was 1x 120mm rad. Surely for Xfire R9 290s i need a 240mm and 200m at least. no?

Yep; that's about the same idea I use. 240mm radiator hooked up to cool the R9 290 in CrossFireX configuration. The CPU itself would be cooled by a single 120mm radiator. I should've been more specific. My apologies. I meant that you don't need a 240mm + 200mm radiators. You can if you want. :) 

I don't own a Corsair 600T. How much room do you have for radiators accounting in the motherboard and HDDs? Can you use thick radiators or thin ones? For thin radiators, 240mm + 200mm would not be enough. But with thick radiators, the two setups will be fine.

thankyou. It would be easier, space wise to fit a 240mm and a 200mm than a 240mm and 120mm as i thing the 240 and 120 might be too close. and if i'm going with 2 radiators, might as well get the maximum cooling i can. the 240 would have to be about the same thickness a h100i. The case looks amazing and for 99% of people would be 10/10, but its water cooling options, despite its size are a bit crap. I'm interested to see if the newly announced 780t fixes a few issues. Currently the h100i rad goes inside the top, and the fans sit outside the main cage, just inside a mesh: http://img.hexus.net/v2/cooling/Corsair/H100i/H100i-10b...

Interesting. Found this image of someone's build. I must admit, it looks pretty good. A bit of a tight fit. Looks very claustrophobic in there but it everything looks good. I'm not sure how that reservoir is mounted in that image. It looks like it's sitting on top of a SSD/HDD cage. Not sure how much space that reservoir takes up either. Even with water cooling, it would still be ideal if the reservoir does not block the fan's airflow.

I plan to use an XSPC dual 5.25" drive bay res and pump

Sounds good. The XSPC radiators are quite thick for better cooling. :)  I've only played with the XSPC Raystorm once and it didn't last long before I decided to do a custom water loop myself.
