So, I got a flashed ATI Radeon HD 4870 off eBay. It's running fine, but it revs for every little thing I do. Every time I scroll on a webpage...It's revving for every letter I type. The faster I type, the louder it gets. If I watch a video, it runs at high speed. The X1900 XT was quiet compared to this thing. It's like it's set to run the fan as high as it can for every little thing that happens. What do I do? I also just tested it in WoW, and it was getting about 12FPS in Shattrath at full graphics. I think I remember my x1900 getting the same, if not better. Something's gotta be wrong. Now it's just constantly running its fans, and I'm not even doing anything. I'm on my Macbook. My Mac Pro is just sitting there, nothing but the Finder. I'm also not happy with the speed it renders video compared to my dinosaur x1900 XT. Not worth the upgrade. Could the ROM they flashed it with be bad?
