Hello everyone, I decided to join here and ask some question about my Visiontek 3870 OC Edition card I bought back in June. I have been having issues with the card heating up too much so I decided to edit my BIOS and add the PowerPlay features manually as well as tinkering with the fan options to try and remedy the loud fan. I was successful with the PowerPlay options as my card now down clocks when I am not running a 3D application however my fan fix doesn't seem to work as well as I would have hoped. I decide to take a few BIOS files I found around the web and edit those settings into my current BIOS I extracted using GPU-Z. Original BIOS Fan settings: Settings from a fan fix BIOS: My current BIOS settings: OK so this is what I am experiencing. My card will not speed the fan up properly when a 3D application is running. My temps hit about 80°C and the fan was at 40%. I used CCC and GPU-Z to test my setting while running TF2 in windowed mode. I'm hoping someone here can help me with this. My card is the Visiontek 3870OC Edition Rev. 1.0.
