I'd really appreciate it if you would look into the following prob ASAP, since all I got from Sapphire's tech support was a plain quasi tech nonsense and a faulty condition confirmation refusal in a rather rudimentary English (Ticket No. 37890).
After about 120 hours of nice and silent operation at ca. 1100-1300 RPM fan speed in 20-30*C range during zero to moderate 2D load, my brand new HD7850 (SKU 11200-07-20G, non-OCed) switched to permanent and way too excessive 1850-1900 RPM right from the startup at 20*C. In other words, it is obvious that the GPU fan controller acoustic enhancement mode hardware logic and/or BIOS has been failed miserably and granted, I am not going to use faulty Sapphire product nor to permanently tweak fan speed via software.
Obviously, all I need from Sapphire at this point in accordance with the EU consumer law, is a faulty condition confirmation to facilitate smooth and painless RMA service at an original place of purchase (GPU-Z logs, etc. available upon request).
Also, I would like to remind you that I paid for a Sapphire card providing "quiet .. operation during normal operating conditions" (source: http://www.sapphiretech.com/presenta...n=&lid=1&leg=0) and not for a noisy grinding machine (to say the least).
Thank you for your understanding!
