Hello all,
My current setup is as follows:
ASUS P6T motherboard
Radeon HD5870 Graphics card (OEM model I believe) (GPU-Z screenshot http://i.imgur.com/K6TA2Gh.png)
Intel i7 960 Processor
Seagate Barracuda 1TB and 500GB harddrives
Corsair HX750 Power Supply
2x 3x2GB OCZ Platinum RAM
HP ZR24w 1920x1200 Monitor
The fan on my graphics card recently failed, and since then I have been running it 'passive cooled', with the plastic housing removed, and no fan attached. For obvious reasons, this causes the card to overheat somewhat, and throttle. (See furmark screen capture below)

I would like to attempt undervolting my card to see if I can drop the temperature a bit without loosing performance, but I am having some trouble doing so.
The guides I found recomend using TechPower's Radeon BIOS editor to deal with voltage changes to this card. However, the screen captures don't seem to be the same as what I see. The following imafe shows the BIOS editor after I have loaded in my cards BIOS (Saved from GPU-Z). The guides say that there should be some voltages listed in the BIOS voltage table, but this box is empty.

Alternatively, I have found reference to changing the voltage in the drop down list below each 'Clock info' tab, but these also have no adjustable options.

Can anybody here give me some guidance on undervolting this card, or point me to some useful resources?
In addition, is this method likely to give me any sort of visible temperature drop, or should I abandon this endeavor entirely?
Thanks!
By the way, just to be clear, I do understand that running a graphics card at 96 C is a terrible idea, and will probably cause my graphics card to melt sooner rather than later. When that happens, I will just replace the card; it doesn't seem worth the money to buy an aftermarket cooling solution at this point. If some of you can convince me otherwise, please do!
