Your playing with fire, and im not kidding. VRMs get hotter then the GPU on the GTX460. With tock cooling, if your GPU is 70c, your VRMs are 80c+. I had SLI GTX460 (asus) with a 92mm fan blowing to the VRMs heatsink on the cards and these heatsink were VERY hot. I mean VERY.
GTX460 under load, See yourself.
