Decided to downgrade my Arctic AIO from 420 to Arctic 360 A-RGB, mainly so that I can now fit the Toxic 360 rad into my case properly rather than having the roof off and resting it on top.
Due to the downgrade and having more space, I was also able to have the barbs at the bottom rather than the top for the Arctic AIO. Should mean I get less gargling noises and I've certainly not heard any so far.
Looks a lot more tidy than it did, but it was a tight fit getting everything into the Phanteks P600s case.
Back's gone now with all that bending over.
@Kaapstad - Please can you update my picture for the roll of honour? Thanks.
Last thing I need to do is replace the rear fan for an Arctic A-RGB 120mm fan to match the CPU AIO.
