jumper2high: So? In most cases just notes what's specific and what should be taken care of when using IX with particular piece of cooling hardware, why cry loud Not Compatible With Most Of Water Blocks / Coolers!!! (sorry, that's how i interpreted your post).
Like reflowing longer with big top air coolers, changing to spring clamping mount for coolers without such, or that gold plating might be lost on some specific variant of HF (i'm guessing that it's 1:1000 from all HF sold worldwide at most), or isolating mounting bolts from cpu lid, or using less clamping force. I doubt ever seeing someone buying IX to be used with stock oem cooler, and don't know is it really that big issue with coolers of direct touch heatpipes with gaps, as imho some IX will stay nevertheless between base of cooler and IHS.
And i wonder .. how Vapor could test IX in his TIM test on such "incompatible" water block, huh?
