Will adding a shim void my warranty?
P.S The heatpipes explain the core temp, but what about the vrm? Why are they so hot? (I'm looking at the pic posted a few pages behind)
I think those VisionTek cards only carry a 1-year warranty? I would say hold out for the DC2 block, it will undoubtedly bring the temps within reason, and take advantage of the ASUS 3-year warranty.
I sold my 7870 to a friend, of a friend, of a friend, lol. He managed to blow it up somehow...it was running "stock clocks" when this happened; which I find hard to believe. I RMA'd it for the guy, and it was a smooth transaction, especially since I called in the RMA. Only took a like 9-10 days total including transit time there and back; RMA center is in Indiana.
Taking off stock heatsink doesn't void your warranty with ASUS cards. As long as you don't do any damage to the card, you would be fine. Just have to make sure you use non-conductive TIM(in case you get some where you shouldn't) and that the shim isn't touching anything that could cause a short.
VRMs get very hot on these cards especially with OC and additional voltage. Even under water I was initially seeing high 70s on VRM1 with a healthy overclock. I got the temperatures down by upgrading thermal pads. I have a write up on that in my sig if you want to check it out.
The one thing the stock blower does halfway decently is cool VRM1 since all the cool air hits those first...this consequently sends very hot air over the core, which is likely a good portion of the reason the reference cooler does such a poor job cooling the core.
