Reduce Sapphire Toxic Radeon HD4870 Fan Noise E-mail

The Sapphire Toxic Radeon HD4870 512MB graphics card was recently reviewed at and it definitely proved itself as a high end card ready for any 3D gaming action you could throw at it. The main downside was that the fan on the funky looking cooler was noisier than what I considered to be acceptable. Considering that the GPU temperature on the Sapphire Toxic Radeon HD4870 ran 19 to 31 degrees Celsius cooler than the GPU on a stock Sapphire Radeon HD4870, it seemed like a better balance between noise and cooling could be found.

Just before publishing the review of the Toxic Radeon HD4870, the representative from Sapphire sent an e-mail with two files attached; ATI WinFlash v2.0.15 utility and BIOS file 85VCTOXI.008. The BIOS file was developed specifically to address complaints about noise with the Toxic Radeon HD4870, and the flash utility provides a simple, Windows-based means of applying it. I finally had an opportunity to install this BIOS file, and decided to document the results. BigBruin
