You installed the Arctic Accelero 4 unit? Doing anything to the VRMs will have no effect on the GPU temps I think. Perhaps remove the heat sink, clean it up and reapply TIM, and then reinstall the cooler.
I think you may have linked the right one, I don't see a 5 in there at all. Is it the one with the backplate?Awww I linked wrong one lol it's the Arctic extreme 5 I'm waiting on the order to arrive they will go on the ram models of the Titan X maxwell I have I'm thinking of putting the blue silicon on the vrms. The shims are 1.2mm high other ones I have were 1.5 they were too high to install the cooler properly
