Does anyone know if chaining the Heat sink on the SAPPHIRE VAPOR-X HD 4890 2GB the same as any other video card....reason I am asking is this peculator card has extra cooling fins on the bottom for the extra ram (see pic) and I am not shore if I would have to remove that to get the stock heat sink of (or even how I would go about removing it).

Although, the vapor x cooling is great so i would rather you just remove the current hsf, clean it, clean GPU chip and re-apply thermal paste and sink and you should be fine. I did this with my XFX 4890 and dropped my temps by 5 degrees.

The reason you are getting high idle temps is not because your cooling is not effective, it could just be that the heat sink was not seated properly or that you have minimal airflow or just high room temperature. My 4890 idles at about 42 degrees with fan at 55%. The vapor-x cooling is better than the XFX stock cooler which means that buying a new heat sink is a waste.

You said they are both idling at 65 degrees. This means you have 2 cards right? If you are running crossfire then your temps will definitely be higher than normal. And btw, the top will be much hotter than the bottom card, MUCH higher.
