Questions - first time custom loop for 2x 290

[NukeDukem]

Hello,
While I love the performance of my dual 290's in CFX, I have decided the noise is a bit much and would like to water cool them. I just ordered a pair of these http://www.aquatuning.us/product_info.php/info/p16182_Aquacomputer-kryographics-Hawaii-for-Radeon-R9-290X-und-290-acrylic-glass-edition.html water blocks.

Other than the blocks, I realize I'll need a pump, reservoir, radiator, tubing and fittings. I have a couple Q's:

My CPU is cooled by an AIO Corsair H100i which uses up the top 2x120mm radiator slot on my Storm Stryker case. Should I keep this or is it better idea to sell the H100i and add the CPU to the loop?
I am assuming that I will need 2x120mm radiator for the two GPU's, is this ok? Are there any pump, res, or radiator combos that you guys would recommend?

I bought the Aquacomputer blocks on a bit of an impulse but aside from the blocks I don't know much about the other components I'll need and I want to make sure I order parts that all work together w/ my case. Budget isn't huge concern but I want to keep it below $500 (not including the cost of the blocks) if possible!

Thanks for any suggestions especially in regards to what I should do about the CPU cooling!

Well after doing some research on my own I have come up with this final list of parts:

2x kryographics Hawaii for Radeon R9 290X and 290 acrylic glass edition (already purchased)

1x AquaComputer Pump Adapter w/ Aqualis Reservoir and Pump Installed
Base Style: Aqualis D5 Base
Reservoir Style: Aqualis Base Pump Adapter-45
Pump Style: Swiftech MCP655-B

1x Alphacool NexXxoS Monsta Triple 120mm Radiator - 80mm Thick!!

1x Alphacool NexXxoS ST30 Full Copper Slim Profile Single 140mm Radiator

3x Scythe Gentle Typhoon 120mm x 25mm Fan - 1450 RPM

10x Bitspower G1/4 Thread 1/4" ID x 3/8" OD Compression Fitting - Matte Black

12ft. Tygon R-3400 1/4" ID (3/8" OD) - Laboratory Tubing - Black

1x Aquacomputer Kryoconnect Kit for Kryographics - 1-2 Slot

1x IandH Silver KillCoils - Antimicrobial .999 Fine Silver Tubing / Reservoir Strip


It seems these should all be compatible with one another, is this everything I need ? My plan is to mount the 360mm radiator in the front of the case and the 140mm externally on the back of the 140mm exhaust fan in back of the case., and the pump/res wherever I can find room. I decided I'll leave the CPU in the separate AIO Corsair H100i loop mounted to the top 240mm radiator. I have 4g of Arctic MX-4 paste I will use for the GPU thermal compound.

Will the 500mm of total radiator size be enough for overclocked 290's? Anything else I am missing or any suggestions/feedback before I buy all this stuff?

Thank you for any replies!

That will be plenty of radiator space for the 2 video cards. I would recommend Primochill advanced LRT tubing.

I plan on doing the same, just wondering what the total of is for everything?

You might want to get a different pump / reservoir, theres quite a bit of a pressure drop with the aqualis with pump adapter. If you get a separate top, and connect to the aqualis you will get much better performance. This might not be much of an issue though if your just using it for the 2 cards
Here is the link (compares to the new XSPC Photon).

I also like my Primochill advanced LRT

Finally I would avoid a silver kill coil, silver + nickle is not the best combo, and the aqualis uses nickle plating.

Did you get the active cooling backplates for the GPU blocks? Only $100 more but it seemed to work well afor cooling the VRMs according to reviews.
