The VRM cooling on the DCUII is identical to the one used on the 780 version and it works just fine. I didn't see a single 780 DCUII fail from VRM overheating since June 2013.
VRMs on my 7970s have been running at 105C 24/7 since the first day I got the cards. What's your point? Do you have evidence that VRM tempeartures of 87C are dangerous?
If you did your research, you would have known that many GPUs from NV and AMD have the back of the
PCB where the VRMs are hitting 83-97*C at stock settings. This is absolutely nothing to worry about. Most VRMs are rated at 120-130C.
If only its real world price was at $450 or below. Feel sorry for those who wasted $1K on a Titan for gaming and now an after-market R9 290 is as fast/faster 10 months later. Another interesting observation is 770 OC got beaten by R9 280X in every single test except SC at 1080p.
