I have the Elsa Erazor X, too. As you posted, the GPU's on these Vidcards get HOT. If your warranty on the Elsa is already expired, I suggest removing the ADDA miserable excuse for a fan from it. I replaced my ADDA stock fan with the tallest 40mm Sunon fan I've ever seen. This puppy moves nearly 9 cfm, which sure doesn't sound like much! However, I think the ADDA moves less than 3 cfm. There's a big difference!
GF 256's suck power through the AGP slot, big time. Unburdening the AGP slot from the current drawn by the GPU's HSF is a good idea.
The truly brave remove the stock fan AND heatsink from their Vidcards, and replace them with beefier hardware. I can't spare my GF 256. If I rip the top off the GPU while trying to remove the stock HSF, all I have to replace it are a TNT2 Vanta and V330. Ugh!
