Adding Crossfire R9 290x's to my existing loop.

Hello guys, this is first post here allthough i have always used OcUK for buying my computing components.

I built my first watercooled pc a few weeks ago, the loop is only currently used to cool my cpu and mosfet(built in asus maximus vi formula) the plan was use more than enough radiatiors to upgrade in the future but im not sure its enough to efficiently cool two R9 290x's aswell in the same loop.

My watercooling setup uses two radiators, a 360mm Hardware labs black ice SR-1(which is pretty thick i guess) and a thinner 240mm Hardware labs black ice stealth gt. Both radiators are set up as push-pull with 10 Corsair sp120's. The pump/res is the XSPC D5 Vario Dual Bay combo which should be powerfull enough for the loop?

I already have one R9 290x on air but im ready to pull the trigger on another and the waterblocks to go with them, any info would be helpful as to if it would be worth doing, thanks in advance.

Dont know why it looks pink, its red haha and i really need to install some 90 degree fittings also.

I'm not exactly sure what you want people to reply with, fit the blocks and run the cards in serial. No performance comparison but the difference is normally small between xspc & EK blocks.

Im sorry, what im meaning to ask as im new to watercooling(have never watercooled a gpu before) would you recommend adding them to my loop? is my current setup sufficient enough to add them to my loop and how much will the gpu's temperatures effect my cpu's cooling.
 
Aren't the 290x GPUs almost as hot as the sun? :D

Watercooling would definatly be worth it but you'd definatly see a rise in your cpu temps. I think 540mm of rad would be sufficient but would be pretty high temps(high for watercooling).

What's your cpu load vs idle?

Also not sure if its the angle of the photo but the tube between your cpu and mobo block looks a bit too tight.
 
I think the OP join between CPU and MOBO look okay as he used extra long tubing to join to avoid kink. I think 540mm of rad for the setup would be okay, though an extra 240 somewhere would go a long way!

From looking at your picture, i think you could use acrylic tubing and 90 degree fittings to join the mobo, CPU and top most GPU without needing to bend the acrylic. Just use adapters to get the height of 90 degree fittings to line up. Did a similar set up with very similarly placed blocks in my project log. Have a 290x under water now (540mm of rads) and doesn't get past 45 degrees at 1200/1500 and CPU is an fx 8350 @ 5.1GHz, so i think my loop could certainly take another 290x heat wise.

Your setup is more than enough for the additional graphics cards, your CPU temps will go up but shouldn't be a problem.
 
Thanks for all the feedback guys, i guess i will have to go for it, will have to be next week as i best get the christmas presents ordered first.

About my looping hoses, i kinda rushed my build with only straight compression fittings, the link between my cpu isnt kinked but i agree it doesnt look very good. I will definitely add some 90 degree fittings and try acrylic hose as suggested when i install my gpu coolers.

For ther one that asked my CPU(4770k @ 4.5) runs at a tad over room temp when idle and high 40s to mid 50's under prime with fans turned right down and pump speed between 1 and 2.

edit: one more question, should i use a parallel or series bridge between gpu's?
