Yea, those are the Swiftech mosfet sinks from the 8800 series. I thermal taped them together and installed them as a whole one piece heat sink over the VRMs. A low speed yate sits over the top.

My VRM temps during Furmark hit tops of 84c and thats at 860mhz. I can game and benchmark at 890mhz including COD4, Crysis, Stalker, Grid, etc, haven't tried Furmark at 890 mhz though yet. I will just to see. With my setup the core doesn't break ~38deg c. Using Cats 8.8 Furmark doesnt push the VRM past 85deg c.

As for stability, I ran 3dmark but as everyone else gaming is the real stability test. Yes, its completely game / bench stable at 890, but I run 850 or lately 860 24/7. I flashed this card (Asus non TOP) with the Asus TOP bios and this thing has proven to be a monster. The first HIS HD4870 I had died at stock settings after about 2 weeks. But the Asus has proven to be a crazy overclocker.
