Sorry its me again 
I have definitely defintely, finally made the decision to not go with the H100i or Fathom All In One for cpu water cooling, but instead I am going to take the plunge (pun intended)
to do a full water cooling setup.
I will be using the XPSC Raystorm EX280 and this will be going into the Corsair 750D not the Corsair 540 case as I originally had planned.
So now that I decided on:
- Corsair 750D
- XSPC Raystorm 750 EX280 WaterCooling Kit
- Mayhems Ultra Pure H2O 5Ltr
I figured I may aswell watercool the GPU if possible, which is going to be the Sapphire R9 280X Toxic 3GB.
So my question would be, firstly would this watercooling setup be capable of cooling both the i7-4770k (planned to overclock) and the R9 280X Toxic?
If the above is yes, then my question would be how much more difficult to watercool the GPU? So I take the stock heatsink and fans off, clean the old TIM off and reapply new, put included adhesive strips from new GPU waterblock and then connect the watercooling tubes?
Thanks for your help!
