I purchased two http://www.amazon.com/gp/product/B00NI5DA2E/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

to run in sli along with pumps and http://www.nzxt.com/product/detail/138-kraken-g10-gpu-bracket.html

They told me I NEEDED VRM Syncs or I WILL fry out my graphics cards. I have no idea what a VRM Sync is and they weren't any help at all in telling me what I needed. Does anyone know what I need to do to get my liquid cooled systems going with my graphics acrds? What VRM Syncs do I need exactly? Thank you very much.

Yes, you need to either put heatsinks on the little black squares around the Gpu those are your Vrm's, one sink on each Vrm and keep an eye on them forever! They have a tendency to come loose over time and with heat so when you sèe one sagging, push it back on with a plastic or wooden tool because if it falls of and shorts something it aint good,
also consider a fan blowing towards the cards to help cool things further

So wait, I need 48 heat sinks and I need to monitor all of them incase they fall off? Am I getting this right? I really need 6x 8 packs of the heat sinks linked? 6 packages of 8?
