Hey all
I was hoping someone in here could help me and my friend Aaron, who is the one in need of some expert guidance. He just bought a XFX Radeon HD4890 model number ZSFR at bestbuy.

Here it is listed at the bottom of their product line at XFX.

Now he wants to do some overclocking, and has bought an aftermarket cooler - Zalman VF1000, and I told him to be concerned about the voltage regulators, because they get extremely hot if they do not have something to cool them down. I asked if he could tell me his current VRM temperatures, but neither GPU-Z, Rivatuner or Everest Ultima will show them, (not sure he has the full package of Everest though).
Now I am on a GTX 285 which I know does not have the Volterra chip, but his should have that one, which is why I am puzzled by the fact GPU-Z will not show the VRM temperatures as VDDC Slave 1,2,3 etc.
I know that if his XFX 4890 ZSFR is not a reference card, he will not be able to see these, but all my search tells me, that it is a reference card. Am I missing something here?
Should Rivatuner 2.24 not also be able to show the VRM temperatures? I know you have to enable something, but perhaps I guided him wrong on that part - could someone explain the procedure so that my friend does not need to worry about frying his card. He is thinking about buying a Zalman ZM-RHS90 to keep the volatge regulators cool, and I told him that that one would fit - hopefully I am not wrong about that? Here is the link to that VRM cooler.

Any help here would be higly appreciated, because I must have spent 10 hours searching the net for answers - thanks.
