Existing EKWB and XSPC blocks will already get the CPU/GPU temps so low that any overclocker will hit voltage max long before temps become an issue. On water, my 4670k idles at mid-to-high 20's and on heavy load p95 settles in at low 60's. Glad to see progress being made here. But I'm wondering how necessary it is. Rather, I'd like to see them working to bring the cost of custom w/c down so that more people can get into it.
