I just built my new PC and I have a problem with my Sapphire ATI HD 4890: actually it's like the fan is running at 100% all the time !
The only quiet moment that I have with it is the first 2-3 seconds when turning on the pc. Once in the bios, the GPU fan runs at full speed. Even when I try to manually set its speed using Control Center, it does not work.
Does anyone have an idea on what might be causing this ?
Thanks in advance

At near 100% fan speed, with the card being 55C, I'd say you should look into an aftermarket cooler. If the fan keeps up this pace (especially if you head up into the 70's when gaming), the fan'll die soon.
At 60% (manual setting) fan speed my card sits at about 40°C, however it's the Sapphire Vapor-X version. When letting it control itself, it'll sit around 55°C at ~30% fan speed. Also, my card is overclocked 50 MHz on the core and 95 MHz on the memory, so that means it'd sit even lower if I set it back to default clocks.
Regardless, you may have gotten a faulty card. It'd be best to contact whoever you bought it from and RMA.
